Copyright (C) 2012-2023 Free Software Foundation, Inc.
See the end of the file for license conditions.

Please send Org bug reports to mailto:emacs-orgmode@gnu.org.

* Version 9.7 (not released yet)
** Important announcements and breaking changes
*** =python-mode.el (MELPA)= support in =ob-python.el= is removed

=python-mode.el= support has been removed from =ob-python.el=.  The
related customization =org-babel-python-mode= has been changed to a
constant.

If you still want to use python-mode with ob-python, you might
consider [[https://gitlab.com/jackkamm/ob-python-mode-mode][ob-python-mode-mode]], where the code to support python-mode
has been ported to.

** New and changed options
*** New custom setting ~org-icalendar-ttl~ for the ~ox-icalendar~ backend

The option ~org-icalendar-ttl~ allows to advise a subscriber to the
exported ~.ics~ file to reload after the given time interval.

This is useful i.e. if a calendar server subscribes to your exported
file and that file is updated regularly.

See IETF RFC 5545, Section 3.3.6 Duration, and
https://en.wikipedia.org/wiki/ICalendar#Other_component_types for
details.

Default for ~org-icalendar-ttl~ is nil.  In that case the setting will
not be used in the exported ICS file.

The option may also be set using the ICAL-TTL keyword.

*** ~org-clock-x11idle-program-name~ now defaults to =xprintidle=, when available

When =xprintidle= executable is available at =org-clock= load time, it
is used as the default value for ~org-clock-x11idle-program-name~.
The old =x11idle= default is used as the fallback.

=xprintidle= is available as system package in most Linux
distributions, unlike ancient =x11idle= that is distributed via WORG.

*** New options for the "csl" citation export processor's LaTeX output

The ~org-cite-csl-latex-label-separator~ and
~org-cite-csl-latex-label-width-per-char~ options allow the user to
control the indentation of entries for labeled bibliography styles
when the "csl" citation processor is used for LaTeX export.  The
indentation length is computed as the sum of
~org-cite-csl-latex-label-separator~ and the maximal label width, for
example:

#+begin_example
    indentation length
<------------------------->
max. label width  separator
<---------------><-------->
[Doe22]                    John Doe. A title...
[DoeSmithJones19]          John Doe, Jane Smith and...
[SmithDoe02]               Jane Smith and John Doe...
#+end_example

The maximal label width, in turn, is calculated as the product of
~org-cite-csl-latex-label-width-per-char~ and the maximal label length
measured in characters.

The ~org-cite-csl-latex-preamble~ option makes it possible to
customize the entire LaTeX fragment that the "csl" citation processor
injects into the preamble.

*** New ~org-latex-listings-src-omit-language~ option for LaTeX export

The ~org-latex-listings-src-omit-language~ option allows omitting the
=language= parameter in the exported =lstlisting= environment.  This
is necessary when the =listings= backend delegates listing generation
to another package like =fancyvrb= using the following setup in the
document header:

#+BEGIN_src org
,#+LATEX_HEADER: \RequirePackage{fancyvrb}
,#+LATEX_HEADER: \DefineVerbatimEnvironment{verbatim}{Verbatim}{...whatever...}
,#+LATEX_HEADER: \DefineVerbatimEnvironment{lstlisting}{Verbatim}{...whatever...}
#+END_src

*** New face: ~org-agenda-calendar-daterange~
The face ~org-agenda-calendar-daterange~ is used to show entries with
a date range in the agenda.  It inherits from the default face in
order to remain backward-compatible.

** New features
*** Datetree structure headlines can now be complex

TODO state, priority, tags, statistics cookies, and COMMENT keywords
are allowed in the tree structure.

* Version 9.6

** Important announcements and breaking changes
*** =python-mode.el (MELPA)= support in =ob-python.el= is deprecated

We no longer aim to support third-party =python-mode.el= implementation of Python REPL.
Only the built-in =python.el= will be supported from now on.

We still keep the old, partially broken, code in =ob-python.el= for
the time being.  It will be removed in the next release.

See https://orgmode.org/list/87r0yk7bx8.fsf@localhost for more details.

*** Element cache is enabled by default and works for headings

The old element cache code has been refactored.  Emacs does not hang
anymore when the cache is enabled.

When cache is enabled, ~org-element-at-point~ for headings is
guaranteed to return valid =:parent= property.  The highest-level
headings contain new =org-data= element as their parent.

The new =org-data= element provides properties from top-level property
drawer, buffer-global category, and =:path= property containing file
path for file Org buffers.

The new cache still need to be tested extensively.  Please, report any
warning coming from element cache.  If you see warnings regularly, it
would be helpful to set ~org-element--cache-self-verify~ to
='backtrace= and provide the backtrace to Org mailing list.

*** Element cache persists across Emacs sessions

The cache state is saved between Emacs sessions.  Enabled by default.

The cache persistence can be controlled via
~org-element-cache-persistent~.

*** Users experiencing performance issues can use new folding backend

The old folding backend used in Org is poorly scalable when the file
size increases beyond few Mbs.  The symptoms usually include slow
cursor motion, especially in long-running Emacs sessions.

A new optimized folding backend is now available, and enabled by
default.  To disable it, put the following to the Emacs config *before*
loading Org:

#+begin_src emacs-lisp
(setq org-fold-core-style 'overlays)
#+end_src

Even more performance optimization can be enabled by customizing
=org-fold-core--optimise-for-huge-buffers=.  However, this option may
be dangerous.  Please, read the variable docstring carefully to
understand the possible consequences.

When =org-fold-core-style= is set to =text-properties=, several new
features will become available and several notable changes will happen
to the Org behavior.  The new features and changes are listed below.

**** Hidden parts of the links can now be searched and revealed during isearch

In the past, hidden parts of the links could not be searched using
isearch (=C-s=).  Now, they are searchable by default.  The hidden
match is also revealed temporarily during isearch.

To restore the old behavior add the following core to your Emacs
config:

#+begin_src emacs-lisp
(defun org-hidden-link-ignore-isearch ()
  "Do not match hidden parts of links during isearch."
  (org-fold-core-set-folding-spec-property 'org-link :isearch-open nil)
  (org-fold-core-set-folding-spec-property 'org-link :isearch-ignore t))
(add-hook 'org-mode-hook #'org-hidden-link-ignore-isearch)
#+end_src

See docstring of =org-fold-core--specs= to see more details about
=:isearch-open= and =:isearch-ignore= properties.

**** =org-catch-invisible-edits= now works for hidden parts of the links and for emphasis markers

In the past, user could edit invisible parts of the links and emphasis markers.  Now, the editing is respecting the value of =org-catch-invisible-edits=.

Note that hidden parts of sub-/super-scripts are still not handled.

**** Breaking structure of folded elements automatically reveals the folded text

In the past, the user could be left with unfoldable text after breaking the org structure.

For example, if

#+begin_src org
:DRAWER:
like this
:END:
#+end_src

is folded and then edited into

#+begin_src org
DRAWER:
like this
:END:
#+end_src
The hidden text would not be revealed.

Now, breaking structure of drawers, blocks, and headings automatically
reveals the folded text.

**** Folding state of the drawers is now preserved when cycling headline visibility

In the past drawers were folded every time a headline is unfolded.

Now, it is not the case anymore.  The drawer folding state is
preserved.  The initial folding state of all the drawers in buffer is
set according to the startup visibility settings.

To restore the old behavior, add the following code to Emacs config:

#+begin_src emacs-lisp
(add-hook 'org-cycle-hook #'org-cycle-hide-drawers)
#+end_src

Note that old behavior may cause performance issues when cycling
headline visibility in large buffers.

**** =outline-*= functions may no longer work correctly in Org mode

The new folding backend breaks some of the =outline-*= functions that
rely on the details of visibility state implementation in
=outline.el=.  The old Org folding backend was compatible with the
=outline.el= folding, but it is not the case anymore with the new
backend.  From now on, using =outline-*= functions is strongly
discouraged when working with Org files.

*** HTML export uses MathJax 3+ instead of MathJax 2

Org now uses MathJax 3 by default instead of MathJax 2.  During HTML
exports, Org automatically converts all legacy MathJax 2 options to
the corresponding MathJax 3+ options, except for the ~path~ option in
which now /must/ point to a file containing MathJax version 3 or
later.  The new Org does /not/ work with the legacy MathJax 2.

Further, if you need to use a non-default ~font~ or ~linebreaks~ (now
~overflow~), then the ~path~ must point to MathJax 4 or later.

See the updated ~org-html-mathjax-options~ for more details.

MathJax 3, a ground-up rewrite of MathJax 2 came out in 2019.  The new
version brings modularity, better and faster rendering, improved LaTeX
support, and more.

For more information about new features, see:

https://docs.mathjax.org/en/latest/upgrading/whats-new-3.0.html
https://docs.mathjax.org/en/latest/upgrading/whats-new-3.1.html
https://docs.mathjax.org/en/latest/upgrading/whats-new-3.2.html

MathJax 3 comes with useful extensions.  For instance, you can typeset
calculus with the ~physics~ extension or chemistry with the ~mhchem~
extension, like in LaTeX.

Note that the Org manual does not discuss loading of MathJax
extensions via ~+HTML_MATHJAX~ anymore.  It has never worked anyway.
To actually load extensions, consult the official documentation:

https://docs.mathjax.org/en/latest/input/tex/extensions.html

Lastly, MathJax 3 changed the default JavaScript content delivery
network (CDN) provider from CloudFlare to jsDelivr.  You can find the
new terms of service, including the privacy policy, at
https://www.jsdelivr.com/terms.

*** List references in source block variable assignments are now proper lists

List representation of named lists is now converted to a simple list
as promised by the manual section [[info:org#Environment of a Code Block][org#Environment of a Code Block]].
Previously, it was converted to a list of lists.

Before:

#+begin_src org
,#+NAME: example-list
- simple
  - not
  - nested
- list

,#+BEGIN_SRC emacs-lisp :var x=example-list :results value
(format "%S" x)
,#+END_SRC

,#+RESULTS:
: (("simple" (unordered ("not") ("nested"))) ("list"))
#+end_src

After:

#+begin_src org
,#+BEGIN_SRC emacs-lisp :var x=example-list :results value
(format "%S" x)
,#+END_SRC

,#+RESULTS:
: ("simple" "list")
#+end_src

** New features
*** Clock table can now produce quarterly reports

=:step= clock table parameter can now be set to =quarter=.
*** Publishing now supports links to encrypted Org files

Links to other published Org files are automatically converted to the
corresponding html links.  Now, this feature is also available when
links point to encrypted Org files, like
=[[file:foo.org.gpg::Heading]]=.

*** Interactive commands now support escaping text inside comment blocks

~org-edit-special~ and ~org-insert-structure-template~ now handle
comment blocks.

See [[*New command ~org-edit-comment-block~ to edit comment block at
point]].

*** New customization option =org-property-separators=
A new alist variable to control how properties are combined.

If a property is specified multiple times with a =+=, like

#+begin_src org
:PROPERTIES:
:EXPORT_FILE_NAME: some/path
:EXPORT_FILE_NAME+: to/file
:END:
#+end_src

the old behavior was to always combine them with a single space
(=some/path to/file=).  For the new variable, the car of each item in
the alist should be either a list of property names or a regular
expression, while the cdr should be the separator to use when
combining that property.

The default value for the separator is a single space, if none of the
provided items in the alist match a given property.

For example, in order to combine =EXPORT_FILE_NAME= properties with a
forward slash =/=, one can use

#+begin_src emacs-lisp
(setq org-property-separators '((("EXPORT_FILE_NAME") . "/")))
#+end_src

The example above would then produce the property value
=some/path/to/file=.

*** New library =org-persist.el= implements variable persistence across Emacs sessions

The library stores variable data in ~org-persist-directory~ (set to XDG
cache dir by default).

The entry points are ~org-persist-register~, ~org-persist-unregister~,
~org-persist-read~, and ~org-persist-read-all~.  Storing circular
structures is supported.  Storing references between different
variables is also supported (see =:inherit= key in
~org-persist-register~).

The library permits storing buffer-local variables.  Such variables
are linked to the buffer text, file =inode=, and file path.

*** New =:options= attribute when exporting tables to LaTeX

The =:options= attribute allows adding an optional argument with a
list of various table options (between brackets in LaTeX export),
since certain tabular environments, such as longtblr of the
tabularray LaTeX package, provides this structure.

*** New =:compact= attribute when exporting lists to Texinfo

The =:compact= attribute allows exporting multiple description list
items to one =@item= command and one or more =@itemx= commands.  This
feature can also be enabled for all description lists in a file using
the =compact-itemx= export option, or globally using the
~org-texinfo-compact-itemx~ variable.

*** New shorthands recognized when exporting to Texinfo

Items in a description list that begin with =Function:=, =Variable:=
or certain related prefixes are converted using Texinfo definition
commands.
*** New =:noweb-prefix= babel header argument

=:noweb-prefix= can be set to =no= to prevent the prefix characters
from being repeated when expanding a multiline noweb reference.

*** New =:noweb= babel header argument value =strip-tangle=

=:noweb= can be set to =strip-tangle= to strip the noweb syntax references
before tangling.

*** New LaTeX source block backend using =engraved-faces-latex=

When ~org-latex-src-block-backend~ is set to ~engraved~,
=engrave-faces-latex= from [[http://elpa.gnu.org/packages/engrave-faces.html][engrave-faces]] is used to transcode source
blocks to LaTeX. This requires the =fvextra=, =float=, and (by
default, but not necessarily) =tcolorbox= LaTeX packages be
installed. It uses Emacs' font-lock information, and so tends to
produce results superior to Minted or Listings.
*** Support for =#+include=-ing URLs

=#+include: FILE= will now accept URLs as the file.
*** Structure templates now respect case used in ~org-structure-template-alist~

The block type in ~org-structure-template-alist~ is not case-sensitive.
When the block type starts from the upper case, structure template
will now insert =#+BEGIN_TYPE=.  Previously, lower-case =#+begin_type= was inserted unconditionally.
*** New ox-latex tabbing support for tables.

Latex tables can now be exported to the latex tabbing environment
tabbing environment]].
This is done by adding =#+ATTR_LATEX: :mode tabbing= at the top
of the table.
The default column width is set to 1/n times the latex textwidth,
where n is the number of columns.
This behavior can be changed by supplying a =:align= parameter.

The tabbing environment can be useful when generating simple tables which
can be span multiple pages and when table cells are allowed to overflow.
*** Support for =nocite= citations and sub-bibliographies in the "csl" export processor

The "csl" citation export processor now supports =nocite= style
citations that add items to the printed bibliography without visible
references in the text. Using the key =*= in a nocite citation, for
instance,

#+begin_src org
[cite/n:@*]
#+end_src

includes all available items in the printed bibliography.

The "csl" export processor now also supports sub-bibliographies that
show only a subset of the references based on some criterion.  For
example,

#+begin_src org
#+print_bibliography: :type book :keyword ai
#+end_src

prints a sub-bibliography containing the book entries with =ai= among
their keywords.
*** New =:filetitle= option for clock table

The =:filetitle= option for clock tables can be set to ~t~ to show org
file title (set by =#+title:=) in the File column instead of the
file name.  For example:

#+begin_src org
,#+BEGIN: clocktable :scope agenda :maxlevel 2 :block thisweek :filetitle t
#+end_src

If a file does not have a title, the table will show the file name
instead.
*** New =org-md-toplevel-hlevel= variable for Markdown export

The =org-md-toplevel-hlevel= customization variable sets the heading
level used for top level headings, much like how
=org-html-toplevel-hlevel= sets the heading level used for top level
headings in HTML export.
*** Babel: new syntax to pass the contents of a src block as argument

Use the header argument =:var x=code-block[]= or
: #+CALL: fn(x=code-block[])
to pass the contents of a named code block as a string argument.
*** New property =ORG-IMAGE-ACTUAL-WIDTH= for overriding global ~org-image-actual-width~

The new property =ORG-IMAGE-ACTUAL-WIDTH= can override the global
variable ~org-image-actual-width~ value for inline images display width.

*** Outline cycling can now include inline image visibility

New ~org-cycle-hook~ function ~org-cycle-display-inline-images~ for
auto-displaying inline images in the visible parts of the subtree.
This behavior is controlled by new custom option
~org-cycle-inline-images-display~.

*** New ~org-babel-tangle-finished-hook~ hook run at the very end of ~org-babel-tangle~

This provides a proper counterpart to ~org-babel-pre-tangle-hook~, as
~org-babel-post-tangle-hook~ is run
per-tangle-destination. ~org-babel-tangle-finished-hook~ is just run
once after the post tangle hooks.

*** New =:backend= header argument for clojure code blocks

The =:backend= header argument on clojure code blocks can override the
value of ~org-babel-clojure-backend~. For example:

#+begin_src clojure :backend babashka
(range 2)
#+end_src

*** New =:results discard= header argument

Unlike =:results none=, the return value of code blocks called with
=:results discard= header argument is always ~nil~.  Org does not
attempt to analyze the results and simply returns nil.  This can be
useful when the code block is used for side effects only but generates
large outputs that may be slow to analyze for Org.

*** Add Capture template hook properties

Capture templates can now attach template specific hooks via the
following properties: ~:hook~, ~:prepare-finalize~,
~:before-finalize~, ~:after-finalize~.  These nullary functions run
prior to their global counterparts for the selected template.

** New options
*** A new option for custom setting ~org-refile-use-outline-path~ to show document title in refile targets

Setting ~org-refile-use-outline-path~ to ~'title~ will show title
instead of the file name in refile targets.  If the document do not have
a title, the filename will be used, similar to ~'file~ option.

*** A new option for custom setting ~org-agenda-show-outline-path~ to show document title

Setting ~org-agenda-show-outline-path~ to ~'title~ will show title
instead of the file name at the beginning of the outline.  The title of
the document can be set by special keyword =#+title:=.

*** New custom settings =org-icalendar-scheduled-summary-prefix= and =org-icalendar-deadline-summary-prefix=

These settings allow users to define prefixes for exported summary
lines in ICS exports.  The customization can be used to disable
the prefixes completely or make them a little bit more verbose
(e.g. "Deadline: " instead of the default "DL: ").

The same settings can also be applied via corresponding exporter
options:
=:icalendar-scheduled-summary-prefix=,
=:icalendar-deadline-summary-prefix=

*** A new custom setting =org-hide-drawer-startup= to control initial folding state of drawers

Previously, all the drawers were always folded when opening an Org
file.  This only had an effect on the drawers outside folded
headlines.  The drawers inside folded headlines were re-folded because
=org-cycle-hide-drawers= was present inside =org-cycle-hook=.

With the new folding backend, running =org-cycle-hide-drawers= is no
longer needed if all the drawers are truly folded on startup: [[*Folding
state of the drawers is now preserved when cycling headline
visibility]].  However, this has an unwanted effect when a user does
not want the drawers to be folded (see [[https://orgmode.org/list/m2r14f407q.fsf@ntnu.no][this bug report]]).

The new custom setting gives more control over initial folding state
of the drawers.  When set to =nil= (default is =t=), the drawers are
not folded on startup.

The folding state can also be controlled on per-file basis using
=STARTUP= keyword:

: #+startup: hidedrawers
: #+startup: nohidedrawers

*** New custom setting ~org-icalendar-force-alarm~

The new setting, when set to non-nil, makes Org create alarm at the
event time when the alarm time is set to 0.  The default value is
nil -- do not create alarms at the event time.

*** New special value ~'attach~ for src block =:dir= option

Passing the symbol ~attach~ or string ="'attach"= (with quotes) to the =:dir=
option of a src block is now equivalent to =:dir (org-attach-dir) :mkdir yes=
and any file results with a path descended from the attachment directory will
use =attachment:= style links instead of the standard =file:= link type.

** New functions and changes in function arguments
*** New function ~org-get-title~ to get =#+TITLE:= property from buffers

A function to collect the document title from the org-mode buffer.

*** ~org-fold-show-entry~ does not fold drawers by default anymore

~org-fold-show-entry~ now accepts an optional argument HIDE-DRAWERS.
When the argument is non-nil, the function folds all the drawers
inside entry.  This was the default previously.

Now, ~org-fold-show-entry~ does not fold drawers by default.

*** New command ~org-edit-comment-block~ to edit comment block at point

As the contents of comments blocks is not parsed as Org markup, the
headlines and keywords inside should be escaped, similar to src
blocks, example blocks, and export blocks.  This in inconvenient to do
manually and ~org-edit-special~ is usually advised to edit text in
such kind of blocks.

Now, comment block editing is also supported via this new function.

*** New function ~org-element-cache-map~ for quick mapping across Org elements

When element cache is enabled, the new function provides the best
possible performance to map across large Org buffers.

It is recommended to provide =:next-re= and =:fail-re= parameters for
best speed.

Diagnostic information about execution speed can be provided according
to ~org-element--cache-map-statistics~ and
~org-element--cache-map-statistics-threshold~.

~org-scan-tags~ and tag views in agenda utilize the new function.
*** New function ~org-element-at-point-no-context~

This function is like ~org-element-at-point~, but it does not try to
update the cache and does not guarantee correct =:parent= properties
for =headline= elements.

This function is faster than ~org-element-at-point~ when used together
with frequent buffer edits.
*** Various Org API functions now use cache and accept Org elements as optional arguments

~org-in-archived-heading-p~, ~org-in-commented-heading-p~,
~org-up-heading-safe~, ~org-end-of-subtree~, ~org-goto-first-child~,
~org-back-to-heading~, ~org-entry-get-with-inheritance~, and
~org-narrow-to-subtree~ all accept Org element as an extra optional
argument.

~org-get-tags~ now accepts Org element or buffer position as first
argument.

*** New function ~org-texinfo-kbd-macro~

This function is intended for us in the definition of a ~kbd~ macro in
files that are exported to Texinfo.

*** =org-at-heading-p= now recognizes optional argument. Its meaning is inverted.

=org-at-heading-p= now returns t by default on headings inside folds.
Passing optional argument will produce the old behavior.

*** =org-babel-execute:plantuml= can output ASCII graphs in the buffer

Previously, executing PlantUML src blocks always exported to a file.  Now, if
:results is set to a value which does not include "file", no file will be
exported and an ASCII graph will be inserted below the src block.

** Removed or renamed functions and variables
*** =org-plantump-executable-args= is renamed and applies to jar as well

The new variable name is =org-plantuml-args=.  It now applies to both
jar PlantUML file and executable.
*** Default values and interpretations of ~org-time-stamp-formats~ and ~org-time-stamp-custom-formats~ are changed

Leading =<= and trailing =>= in the default values of
~org-time-stamp-formats~ and ~org-time-stamp-custom-formats~ are
stripped.

The Org functions that are using these variables also ignore leading
and trailing brackets (=<...>= and =[...]=, if present).

This change makes the Org code more consistent and also makes the
docstring for ~org-time-stamp-custom-formats~ accurate.

No changes on the user side are needed if
~org-time-stamp-custom-formats~ was customized.
*** ~org-timestamp-format~ is renamed to ~org-format-timestamp~

The old function name is similar to other ~org-time-stamp-format~
function.  The new name emphasizes that ~org-format-timestamp~ works
on =timestamp= objects.

*** Updated argument list in ~org-time-stamp-format~

New =custom= argument in ~org-time-stamp-format~ makes the function
use ~org-time-stamp-custom-formats~ instead of
~org-time-stamp-formats~ to determine the format.

Optional argument =long= is renamed to =with-time=, emphasizing that it refers to time stamp format with time specification.

Optional argument =inactive= can now have a value =no-brackets= to
return format string with brackets stripped.

** Miscellaneous
*** SQL Babel ~:dbconnection~ parameter can be mixed with other SQL Babel parameters

Before you could either specify SQL parameters like ~:dbhost~,
~:dbuser~, ~:database~, etc or a ~:dbconnection~ parameter which looks
up all other parameters from the ~sql-connection-alist~ variable.  Now
it's possible to specify a ~:dbconnection~ and additionally other
parameters that will add or overwrite the parameters coming from
~sql-connection-alist~.

E.g. if you have a connection in your ~sql-connection-alist~ to a
server that has many databases, you don't need an entry for every
database but instead can just specify ~:database~ next to your
~:dbconnection~ parameter.

*** Post-processing code blocks can return an empty list

When the result of a regular code block is nil, then that was already
treated as an empty list.  Now that is also the case for code blocks
that post-process the result of another block.

*** Styles are customizable in ~biblatex~ citation processor

It is now possible to add new styles or modify old ones in ~biblatex~
citation processor.  See ~org-cite-biblatex-styles~ for more
information.

*** Citation processors can declare styles dynamically

When a citation processor is registered, it is now possible to set
~:cite-styles~ key to a function, which will be called whenever the
list of styles is required.

*** Org also searches for CSL style files in default directory

When CSL style file name is relative, Org first looks into
default-directory before trying ~org-cite-csl-styles-dir~.

*** Users can add checkers to the linting process

The function ~org-lint-add-checker~ allows one to add personal checks
when calling ~org-lint~.   See its docstring for more information.

*** New =transparent-image-converter= property for =dvipng=

The =dvipng= option in ~org-preview-latex-process-alist~ has a new
property =transparent-image-converter= which is used instead of
=image-converter= when producing transparent images.

*** =:tangle-mode= now accepts more permissions formats

Previously =:tangle-mode (identity #o755)= was the only reasonable way
to set the file mode. ~org-babel-interpret-file-mode~ has been
introduced which will accept three new formats:
+ Short octals, e.g. =:tangle-mode o755=
+ ls-style, e.g. =:tangle-mode rwxrw-rw-=
+ chmod-style, e.g. =:tangle-mode u+x=

Chmod-style permissions are based on the new variable
~org-babel-tangle-default-file-mode~.

*** A new custom setting =org-agenda-clock-report-header= to add a header to org agenda clock report

*** ~org-latex-listings~ has been replaced with ~org-latex-src-block-backend~

~org-latex-listings~ has been renamed to better reflect the current
purpose of the variable.  The replacement variable
~org-latex-src-block-backend~ acts in exactly the same way, however it
accepts =listings= and =verbatim= in place of =t= and =nil= (which
still work, but are no longer listed as valid options).

*** ~org-link-parameters~ has a new ~:insert-description~ parameter

The value of ~:insert-description~ is used as the initial input when
prompting for a link description.  It can be a string (used as-is) or
a function (called with the same arguments as
~org-make-link-description-function~ to return a string to use).

An example of a such function for =info:= links is
~org-info-description-as-command~.  To access a manual section outside
of Org, description may be pasted to shell prompt or evaluated within
Emacs using =M-:= (wrapped into parenthesis).  For example,
description of the =info:org#Tags= link is =info "(org) Tags"=.  To
restore earlier behavior add to your Emacs init file the following:
#+begin_src elisp :results silent :eval never-export
  (with-eval-after-load 'ol-info
    (org-link-set-parameters "info" :insert-description nil))
#+end_src

*** New list of languages for LaTeX export: ~org-latex-language-alist~

~org-latex-language-alist~ unifies into a single list the old language
lists for the =babel= and =polyglossia= LaTeX packages:
~org-latex-babel-language-alist~ and
~org-latex-polyglossia-language-alist~, respectively, which are
declared obsolete.

This new list captures the current state of art regarding language
support in LaTeX.  The new =babel= syntax for loading languages via
=ini= files and the new command =\babelprovide= (see:
https://mirrors.ctan.org/macros/latex/required/babel/base/babel.pdf)
are also supported.
*** Texinfo exports include LaTeX

With the new customization option ~org-texinfo-with-latex~ set to (its
default value) ~'detect~, if the system runs Texinfo 6.8 (3 July 2021)
or newer, Org will export all LaTeX fragments and environments using
Texinfo ~@math~ and ~@displaymath~ commands respectively.
*** More flexible ~org-attach-id-to-path-function-list~

List entries may return nil if they are unable to handle the passed
ID.  So, responsibility is passed to the next item in the list.
Default entries ~org-attach-id-uuid-folder-format~ and
~org-attach-id-ts-folder-format~ now return nil for too short IDs.
Earlier an obscure error has been thrown.

After the change, error text suggests adjusting
~org-attach-id-to-path-function-list~ value.  The
~org-attach-dir-from-id~ function is adapted to ignore nil values and
to take first non-nil value instead of the value returned by first
~org-attach-id-to-path-function-list~ item.

New policy allows mixing different ID styles while keeping subfolder
layout suited best for each one.  For example, one can use the
following snippet to allow multiple different ID formats in Org files.

#+begin_src emacs-lisp
(setq org-attach-id-to-path-function-list
      '(;; When ID looks like an UUIDs or Org internal ID, use
        ;; `org-attach-id-uuid-folder-format'.
        (lambda (id)
          (and (or (org-uuidgen-p id)
	           (string-match-p "[0-9a-z]\\{12\\}" id))
	       (org-attach-id-uuid-folder-format id)))
        ;; When ID looks like a timestamp-based ID. Group by year-month
        ;; folders.
        (lambda (id)
          (and (string-match-p "[0-9]\\{8\\}T[0-9]\\{6\\}\.[0-9]\\{6\\}" id)
               (org-attach-id-ts-folder-format id)))
        ;; Any other ID goes into "important" folder.
        (lambda (id) (format "important/%s/%s" (substring id 0 1) id))
        ;; Fallback to detect existing attachments for old defaults.
        ;; All the above functions, even when return non-nil, would
        ;; point to non-existing folders.
        org-attach-id-uuid-folder-format
        org-attach-id-ts-folder-format))
#+end_src
* Version 9.5

** Important announcements and breaking changes

*** The =contrib/= now lives in a separate repository

Org's repository has been trimmed from the =contrib/= directory.

The old contents of the =contrib/= directory now lives in a separate
repository at https://git.sr.ht/~bzg/org-contrib.

You can install this repository by cloning it and updating your
~load-path~ accordingly.  You can also install =org-contrib= as a
[[https://elpa.nongnu.org/nongnu/][NonGNU ELPA]] package.

*** Org ELPA and Org archives won't be available for Org > 9.5

[[https://orgmode.org/elpa.html][Org ELPA]] is still available for installing Org 9.5, either with or
without contributed packages, but future versions won't be available
via Org ELPA, as we are deprecating this installation method.

Also, Org 9.5 is available as =tar.gz= and =zip= archives, but this
installation method is also deprecated.

If you want to install the latest stable versions of Org, please use
the GNU ELPA package.  If you want to install the contributed files,
please use the NonGNU ELPA package.  If you want to keep up with the
latest unstable Org, please install from the Git repository.

See https://orgmode.org/org.html#Installation for the details.

*** =ditaa.jar= is not bundled with Org anymore

=ditaa.jar= used to be bundled with Org but it is not anymore.
See [[https://github.com/stathissideris/ditaa][the ditaa repository]] on how to install it.

*** ~org-adapt-indentation~ now defaults to =nil=

If you want to automatically indent headlines' metadata, set it to
=headline-data=.

If you want to automatically indent every line to the headline's
current indentation, set it to =t=.

Indent added by =RET= and =C-j= also depends on the value of
~electric-indent-mode~.  Enabling this mode by default in 9.4 revealed
some bugs caused confusing behavior.  If you disabled
~electric-indent-mode~ for this reason, it is time to try it again.
Hopefully problems have been fixed.  See [[https://orgmode.org/worg/org-faq.html#indentation][this FAQ]] for more details.

*** ~org-speed-commands-user~ is obsolete, use ~org-speed-commands~

Setting ~org-speed-commands-user~ in your configuration won't have any
effect.  Please set ~org-speed-commands~ instead, which see.

*** Some =ob-*.el= files have been moved to the org-contrib repo

These files have been moved to https://git.sr.ht/~bzg/org-contrib:

- ob-abc.el
- ob-asymptote.el
- ob-coq.el
- ob-ebnf.el
- ob-hledger.el
- ob-io.el
- ob-J.el
- ob-ledger.el
- ob-mscgen.el
- ob-picolisp.el
- ob-shen.el
- ob-stan.el
- ob-vala.el

See the discussion [[msg::87bl9rq29m.fsf@gnu.org][here]].

*** Compatibility with Emacs versions

We made it explicit that we aim at keeping the latest stable version
of Org compatible with at least Emacs V, V-1 and V-2, where V is the
stable major version of Emacs.

For example, if the current major version of Emacs is 28.x, then the
latest stable version of Org should be compatible with Emacs 28.x,
27.x and 26.x – but not with Emacs 25.x.

See [[https://orgmode.org/worg/org-maintenance.html#emacs-compatibility][this note on Worg]] and [[git::519947e508e081e71bf67db99e27b1c171ba4dfe][this commit]].

*** The keybinding for ~org-table-blank-field~ has been removed

If you prefer to keep the keybinding, you can add it back to
~org-mode-map~ like so:

#+begin_src emacs-lisp
(define-key org-mode-map (kbd "C-c SPC") #'org-table-blank-field)
#+end_src

** New features

*** New citation engine

Org 9.5 provides a new library =oc.el= which provides tooling to
handle citations in Org, e.g., activate, follow, insert, and export
them, respectively called "activate", "follow", "insert" and "export"
capabilities.  Libraries responsible for providing some, or all, of
these capabilities are called "citation processors".

The manual contains a few pointers to let you start and you may want
to check [[https://blog.tecosaur.com/tmio/2021-07-31-citations.html][this blog post]].  If you need help using this new features,
please ask on the mailing list.

Thanks to Nicolas Goaziou for implementing this, to Bruce D’Arcus for
helping him and to John Kitchin for paving the way with =org-ref.el=.

*** Async session evaluation

The =:async= header argument can be used for asynchronous evaluation
in session blocks for certain languages.

Currently, async evaluation is supported in Python.  There is also
functionality to implement async evaluation in other languages that
use comint, but this needs to be done on a per-language basis.

By default, async evaluation is disabled unless the =:async= header
argument is present.  You can also set =:async no= to force it off
(for example if you've set =:async= in a property drawer).

Async evaluation is disabled during export.
*** ~ox-koma-letter.el~ is now part of Org's core

~ox-koma-letter.el~ provides a KOMA scrlttr2 back-end for the Org
export engine.  It used to be in the =contrib/= directory but it is
now part of Org's core.

*** Support exporting DOI links

Org now supports export for DOI links, through its new =ol-doi.el=
library.  For backward compatibility, it is loaded by default.

*** Add a new ~:refile-targets~ template option

When exiting capture mode via ~org-capture-refile~, the variable
~org-refile-targets~ will be temporarily bound to the value of this
template option.

*** New startup options =#+startup: show<n>levels=

These startup options complement the existing =overview=, =content=,
=showall=, =showeverything= with a way to start the document with n
levels shown, where n goes from 2 to 5.

Example:

: #+startup: show3levels

*** New =u= table formula flag to enable Calc units simplification mode

A new =u= mode flag for Calc formulas in Org tables has been added to
enable Calc units simplification mode.

*** Support fontification of inline export snippets

See [[msg:87im57fh8j.fsf@gmail.com][this thread]].

*** New command =org-refile-reverse= bound to =C-c C-M-w=

You can now use =C-c C-M-w= to run ~org-refile-reverse~.

It is almost identical to ~org-refile~, except that it temporarily
toggles how ~org-reverse-note-order~ applies to the current buffer.
So if ~org-refile~ would append the entry as the last entry under the
target heading, ~org-refile-reverse~ will prepend it as the first
entry, and vice-versa.

*** LaTeX attribute ~:float~ now passes through arbitrary values

LaTeX users are able to define arbitrary float types, e.g. with the
float package.  The Org mode LaTeX exporter is now able to process and
export arbitrary float types.  The user is responsible for ensuring
that Org mode configures LaTeX to process any new float type.

*** Support verse and quote blocks in LaTeX export

The LaTeX export back-end accepts four attributes for verse blocks:
=:lines=, =:center=, =:versewidth= and =:latexcode=. The three first
require the external LaTeX package =verse.sty=, which is an extension
of the standard LaTeX environment.

The LaTeX export back-end accepts two attributes for quote blocks:
=:environment=, for an arbitrary quoting environment (the default
value is that of =org-latex-default-quote-environment=: ="quote"=) and
=:options=.

*** =org-set-tags-command= selects tags from ~org-global-tags-completion-table~

Let ~org-set-tags-command~ TAB fast tag completion interface complete
tags including from both buffer local and user defined persistent
global list (~org-tag-alist~ and ~org-tag-persistent-alist~).  Now
option ~org-complete-tags-always-offer-all-agenda-tags~ is honored.

*** Clocktable option =:formula %= now shows the per-file time percentages

This change only has an effect when multiple files are contributing to
a given clocktable (such as when =:scope agenda= has been specified).
The existing behavior is that such tables have an extra 'File' column,
and each individual file that contributes has its own summary line
with the headline value '*File time*'.  Those summary rows also
produce a rollup time value for the file in the 'Time' column.

Prior to this change, the built-in =%= formula did not produce a
calculation for those per-file times in the '%' column (the relevant
cells in the '%' column were blank).  With this change, the percentage
contribution of each individual file time to the total time is shown.

The more agenda files you have, the more useful this behavior becomes.

*** =ob-python.el= improvements to =:return= header argument

The =:return= header argument in =ob-python= now works for session
blocks as well as non-session blocks.  Also, it now works with the
=:epilogue= header argument -- previously, setting the =:return=
header would cause the =:epilogue= to be ignored.

This change allows more easily moving boilerplate out of the main code
block and into the header. For example, for plotting, we need to add
boilerplate to save the figure to a file and return the
filename. Instead of doing this within the code block, we can now
handle it through the header arguments as follows:

#+BEGIN_SRC org
,#+header: :var fname="/home/jack/tmp/plot.svg"
,#+header: :epilogue plt.savefig(fname)
,#+header: :return fname
,#+begin_src python :results value file
  import matplotlib, numpy
  import matplotlib.pyplot as plt
  fig=plt.figure(figsize=(4,2))
  x=numpy.linspace(-15,15)
  plt.plot(numpy.sin(x)/x)
  fig.tight_layout()
,#+end_src

,#+RESULTS:
[[file:/home/jack/tmp/plot.svg]]
#+END_SRC

As another example, we can use =:return= with the external [[https://pypi.org/project/tabulate/][tabulate]]
package, to convert pandas Dataframes into orgmode tables:

#+begin_src org
,#+header: :prologue from tabulate import tabulate
,#+header: :return tabulate(table, headers=table.columns, tablefmt="orgtbl")
,#+begin_src python :results value raw :session
  import pandas as pd
  table = pd.DataFrame({
      "a": [1,2,3],
      "b": [4,5,6]
  })
,#+end_src

,#+RESULTS:
|   | a | b |
|---+---+---|
| 0 | 1 | 4 |
| 1 | 2 | 5 |
| 2 | 3 | 6 |
#+end_src

*** Display images with width proportional to the buffer text width

Previously, if you used a =:width= attribute like =#+attr_html: :width 70%= or
=#+attr_latex: :width 0.7\linewidth= this would be interpreted as a 70px wide and
0.7px wide width specification respectively.

Now, percentages are transformed into floats (i.e. 70% becomes 0.7),
and float width specifications between 0.0 and 2.0 are now interpreted
as that portion of the text width in the buffer. For instance, the
above examples of =70%= and =0.7\linewidth= will result in an image
with width equal to the pixel-width of the buffer text multiplied by 0.7.

This functionality is implemented in a new function,
~org-display-inline-image--width~ which contains the width
determination logic previously in ~org-display-inline-images~ and the
new behavior.

** New options
*** Option ~org-hidden-keywords~ now also applies to #+SUBTITLE:

The option ~org-hidden-keywords~ previously applied
to #+TITLE:, #+AUTHOR:, #+DATE:, and #+EMAIL:.  Now it can also be
used to hide the #+SUBTITLE: keyword.

*** New formatting directive ~%L~ for org-capture

The new ~%L~ formatting directive contains the bare link target, and
may be used to create links with programmatically generated
descriptions.

*** New option ~org-id-ts-format~

Earlier, IDs generated using =ts= method had a hard-coded format (i.e. =20200923T160237.891616=).
The new option allows user to customize the format.
Defaults are unchanged.

*** New argument for ~file-desc~ babel header

It is now possible to provide the =file-desc= header argument for a
babel source block but omit the description by passing an empty vector
as an argument (i.e., :file-desc []).  This can be useful because
providing =file-desc= without an argument results in the result of
=file= being used in the description.  Previously, the only way to
omit a file description was to omit the header argument entirely,
which made it difficult/impossible to provide a default value for
=file-desc=.

*** New option to set ~org-link-file-path-type~ to a function

~org-link-file-path-type~ can now be set to a function that takes the
full filename as an argument and returns the path to link to.

For example, if you use ~project.el~, you can set this function to use
relative links within a project as follows:

#+begin_src emacs-lisp
(setq (org-link-file-path-type
       (lambda (path)
         (let* ((proj (project-current))
                (root (if proj (project-root proj) default-directory)))
           (if (string-prefix-p (expand-file-name root) path)
               (file-relative-name path)
             (abbreviate-file-name path))))))
#+end_src

*** New options and new behavior for babel LaTeX SVG image files

Org babel now uses a two-stage process for converting latex source
blocks to SVG image files (when the extension of the output file is
~.svg~).  The first stage in the process converts the latex block into
a PDF file, which is then converted into an SVG file in the second
stage.  The TeX->PDF part uses the existing infrastructure for
~org-babel-latex-tex-to-pdf~.  The PDF->SVG part uses a command
specified in a new customization,
~org-babel-latex-pdf-svg-process~. By default, this uses inkscape for
conversion, but since it is fully customizable, any other command can
be used in its place. For instance, dvisvgm might be used here. This
two-part processing replaces the previous use of htlatex to process
LaTeX directly to SVG (htlatex is still used for HTML conversion).

Conversion to SVG exposes a number of additional customizations that
give the user full control over the contents of the latex source
block. ~org-babel-latex-preamble~, ~org-babel-latex-begin-env~ and
~org-babel-latex-end-env~ are new customization options added to allow
the user to specify the preamble and code that preceedes and proceeds
the contents of the source block.

*** New option ~org-html-meta-tags~ allows for HTML meta tags customization

New variable ~org-html-meta-tags~ makes it possible to customize the
=<meta>= tags used in an HTML export.  Accepts either a static list of
values, or a function that generates such a list (see
~org-html-meta-tags-default~ as an example of the latter).

*** Option ~org-agenda-bulk-custom-functions~ now supports collecting bulk arguments

When specifying a custom agenda bulk option, you can now also specify
a function which collects the arguments to be used with each call to
the custom function.

*** New faces to improve the contextuality of Org agenda views

Four new faces improve certain styles and offer more flexibility for
some Org agenda views: ~org-agenda-date-weekend-today~,
~org-imminent-deadline~, ~org-agenda-structure-secondary~,
~org-agenda-structure-filter~.  They inherit from existing faces in
order to remain backward-compatible.

Quoting from [[https://list.orgmode.org/87lf7q7gpq.fsf@protesilaos.com/][this thread]]:

#+begin_quote
+ The 'org-imminent-deadline' is useful to disambiguate generic
  warnings from deadlines.  For example, a warning could be rendered
  in a yellow colored text and have a bold weight, whereas a deadline
  might be red and styled with italics.

+ The 'org-agenda-structure-filter' applies to all tag/term filters
  in agenda views that search for keywords or patterns.  It is
  designed to inherit from 'org-agenda-structure' in addition to the
  'org-warning' face that was present before (and removes the
  generic 'warning' face from one place).  This offers the benefit
  of consistency, as, say, an increase in font height or a change in
  font family in 'org-agenda-structure' will propagate to the filter
  as well.  The whole header line thus looks part of a singular
  design.

+ The 'org-agenda-structure-secondary' complements the above for those
  same views where a description follows the header.  For instance, the
  tags view provides information to "Press N r" to filter by a
  numbered tag.  Themes/users may prefer to disambiguate this line
  from the header above it, such as by using a less intense color or by
  reducing its height relative to the 'org-agenda-structure'.

+ The 'org-agenda-date-weekend-today' provides the option to
  differentiate the current date on a weekend from the current date on
  weekdays.
#+end_quote

*** New option ~org-clock-ask-before-exiting~

By default, a function is now added to ~kill-emacs-query-functions~
that asks whether to clock out and save when there's a running clock.
Customize ~org-clock-ask-before-exiting~~ to nil to disable this new
behavior.

*** Option ~org-html-inline-image-rules~ now includes .webp

By default ox-html now inlines webp images.

*** ~org-html-head-include-scripts~ is now =nil= by default

See [[msg:498dbe2e-0cd2-c81e-7960-4a26c566a1f7@memebeam.org][this thread]].

*** New option ~org-html-content-class~

This is the CSS class name to use for the top level content wrapper.

*** New option ~org-babel-plantuml-svg-text-to-path~

This option, nil by default, allows to add a SVG-specific post-export
step that runs inkscape text-to-path replacement over the output file.

*** You can now configure ~org-html-scripts~ and ~org-html-style-default~

~org-html-scripts~ and ~org-html-style-default~ used to be constants,
you can now configure them.

*** New option ~org-attach-git-dir~

~org-attach-git-dir~ will decide whether to use ~org-attach-git-dir~
(the default) or use the attachment directory of the current node, if
it is correctly configured as a Git repository.

*** New option ~org-attach-sync-delete-empty-dir~

~org-attach-sync-delete-empty-dir~ controls the deletion of an empty
attachment directory at calls of ~org-attach-sync~.  There is
Never delete, Always delete and Query the user (default).

*** ~org-babel-default-header-args~ can now be specified as closures or strings

~org-babel-default-header-args~ now also accepts closures that
evaluate to a string. Previously, only direct strings were
supported. These closures are evaluated when point is at the source
block, which allows them to make use of contextual information at the
relevant source block. One example that illustrates the usefulness of
this addition (also given in the documentation for
~org-babel-default-header-args~) is:

#+begin_src elisp
(defun org-src-sha ()
  (let ((elem (org-element-at-point)))
    (concat (sha1 (org-element-property :value elem)) \".svg\")))

(setq org-babel-default-header-args:latex
      `((:results . \"file link replace\")
        (:file . (lambda () (org-src-sha)))))
#+end_src

This will set the ~:file~ header argument to the sha1 checksum of the
contents of the current latex source block.

Finally, the closures are only evaluated if they're not overridden for
a source block. This improves efficiency in cases where the result of
a compute-expensive closure would otherwise be discarded.

** Miscellaneous
*** =org-bibtex= includes =doi= and =url= entries when exporting to BiBTeX
=doi= and =url= entries have been made optional for some publication
types and will be exported if present for those types.
*** Missing or empty placeholders in "eval" macros are now =nil=
They used to be the empty string.
*** =org-goto-first-child= now works before first heading

When point is before first heading =org-goto-first-child= will move
point to the first child heading, or return nil if no heading exist
in buffer.  This is in line with the fact that everything before first
heading is regarded as outline level 0, i.e. the parent level of all
headings in the buffer.

Previously =org-goto-first-child= would do nothing before first
heading, except return nil.

*** Faces of all the heading text elements now conform to the headline face

In the past, faces of todo keywords, emphasized text, tags, and
priority cookies inherited =default= face.  The resulting headline
fontification was not always consistent, as discussed in [[msg::87h7sawubl.fsf@protesilaos.com][this bug
report]].  Now, the relevant faces adapt to face used to fontify the
current headline level.

Users who prefer to keep the old behavior should change their face
customization explicitly stating that =default= face is inherited.

Example of old face customization:

#+begin_src emacs-lisp
(setq org-todo-keyword-faces '(("TODO"
                                :background "chocolate"
                                :height 0.75)))
#+end_src

To preserve the old behavior the above customization should be
changed to

#+begin_src emacs-lisp
(setq org-todo-keyword-faces '(("TODO"
                                :inherit default
                                :background "chocolate"
                                :height 0.75)))
#+end_src

*** Storing ID-links before first heading uses title as description

Storing links to files using ~org-store-link~ (=<C-c l>=) when
~org-id-link-to-org-use-id~ is not nil will now store the title as
description of the link, if available.  If no title exists it falls
back to the filename as before.

*** Change in =org-tags-expand= signature

The function does not allow for a third optional parameter anymore.
*** LaTeX environment =#+results= are now removed

If a babel src block produces a raw LaTeX environment, it will now be
recognized as a result, and so replaced when re-evaluated.

*** Tag completion now uses =completing-read-multiple=

Tag completion now uses =completing-read-multiple= with a simple
completion table, which should allow better interoperability with
custom completion functions.

*** Providing =directory-empty-p= from Emacs 28 as =org-directory-empty-p=

*** =org-get-last-sibling= marked as obsolete

Use =org-get-previous-sibling= instead.  This is just a rename to have
a more consistent naming.  E.g. recall the pair of funtctions
=next-line= / =previous-line=.

*** Make org-protocol compatible with =URLSearchParams= JavaScript class

Decoder of query part of org-protocol URI recognizes "+" as an encoded
space characters now, so it is possible to avoid call to =encodeURIComponent=

*** Remove obsolete LaTeX packages from ~org-latex-default-packages-alist~

The LaTeX packages =grffile= and =textcomp= are redundant, with their
capabilities being merged into =graphicx= and the LaTeX core
respectively a while ago.

* Version 9.4
** Incompatible changes
*** Possibly broken internal file links: please check and fix

A bug has been affecting internal links to headlines, like

: [[*Headline][A link to a headline]]

Storing a link to a headline may have been broken in your setup and
those links may appear as

: [[*TODO Headline][A link to a headline]]

Following the link above will result in an error: the TODO keyword
should not be part of internal file links.

You can use the following command to fix links in an Org buffer:

#+begin_src emacs-lisp
(defun org-fix-links ()
  "Fix ill-formatted internal links.
E.g. replace [[*TODO Headline][headline]] by [[*Headline][headline]].
Go through the buffer and ask for the replacement."
  (interactive)
  (visible-mode 1)
  (save-excursion
    (goto-char (point-min))
    (let ((regexp (format "\\[\\[\\*%s\\s-+"
                          (regexp-opt org-todo-keywords-1 t))))
      (while (re-search-forward regexp nil t)
        (when (and (save-excursion
                     (goto-char (match-beginning 0))
                     (looking-at-p org-link-bracket-re))
                   (y-or-n-p "Fix link (remove TODO keyword)? "))
	  (replace-match "[[*")))))
  (visible-mode -1))
#+end_src

*** Calling conventions changes when opening or exporting custom links

This changes affects export back-ends, and libraries providing new
link types.

Function used in ~:follow~ link parameter is required to accept a
second argument.  Likewise, function used in ~:export~ parameter needs
to accept a fourth argument.  See ~org-link-set-parameters~ for
details.

Eventually, the function ~org-export-custom-protocol-maybe~ is now
called with a fourth argument.  Even though the 3-arguments definition
is still supported, at least for now, we encourage back-end developers
to switch to the new signature.

*** Python session return values must be top-level expression statements

Python blocks with ~:session :results value~ header arguments now only
return a value if the last line is a top-level expression statement.
Also, when a None value is returned, "None" will be printed under
"#+RESULTS:", as it already did with ~:results value~ for non-session
blocks.

*** In HTML export, change on how outline-container-* is set

When the headline has a =CUSTOM_ID=, use this custom id to build the
div id.  For example, if you have =:CUSTOM_ID: my-headline= then the
resulting <div> will be ~<div id="outline-container-my-headline">~.

You may want to check whether your HTML files are rendered differently
after this change.

*** New keybinding =<C-c C-TAB>= for ~org-force-cycle-archived~

~org-force-cycle-archived~ used to be associated with =<C-TAB>= but
this keybinding is used in Emacs for navigating tabs in Emacs.  The
new keybinding is =<C-c C-TAB>=.

** New default settings for some options

These options now default to =t=:

- ~org-loop-over-headlines-in-active-region~
- ~org-fontify-done-headline~
- ~org-src-tab-acts-natively~

You may want to read the docstrings of these options to understand the
consequences of this change.

Also, ~org-startup-folded~ now defaults to ~showeverything~.

** New features

*** =RET= and =C-j= now obey ~electric-indent-mode~

Since Emacs 24.4, ~electric-indent-mode~ is enabled by default.  In
most major modes, this causes =RET= to reindent the current line and
indent the new line, and =C-j= to insert a newline without indenting.

Org mode now obeys this minor mode: when ~electric-indent-mode~ is
enabled, and point is neither in a table nor on a timestamp or a link:

- =RET= (bound to ~org-return~) reindents the current line and indents
  the new line;
- =C-j= (bound to the new command ~org-return-and-maybe-indent~)
  merely inserts a newline.

To get the previous behavior back, disable ~electric-indent-mode~
explicitly:

#+begin_src emacs-lisp
(add-hook 'org-mode-hook (lambda () (electric-indent-local-mode -1)))
#+end_src

Alternatively, if you wish to keep =RET= as the "smart-return" key,
but dislike Org's default indentation of sections, you may prefer to
customize ~org-adapt-indentation~ to either nil or =headline-data=.

*** New allowed value for ~org-adapt-indentation~

~org-adapt-indentation~ now accepts a new value, =headline-data=.

When set to this value, Org will only adapt indentation of headline
data lines, such as planning/clock lines and property/logbook drawers.
Also, with this setting, =org-indent-mode= will keep these data lines
correctly aligned with the headline above.

*** Looping agenda commands over headlines

~org-agenda-loop-over-headlines-in-active-region~ allows you to loop
agenda commands over the active region.

When set to =t= (the default), loop over all headlines.  When set to
='start-level=, loop over headlines with the same level as the first
headline in the region.  When set to a string, loop over lines
matching this regular expression.

*** New minor mode ~org-table-header-line-mode~

Turn on the display of the first data row of the table at point in the
window header line when this first row is not visible anymore in the
buffer.

You can activate this minor mode by default by setting the option
~org-table-header-line-p~ to =t=.  You can also change the face for
the header line by customizing the ~org-table-header~ face.

*** New minor mode ~org-list-checkbox-radio-mode~

When this minor mode is on, checkboxes behave as radio buttons: if a
checkbox is turned on, other checkboxes at the same level are turned
off.

If you want to occasionally toggle a checkbox as a radio button
without turning this minor mode on, you can use =<C-c C-x C-r>= to
call ~org-toggle-radio-button~.

You can also add =#+ATTR_ORG: :radio t= right before the list to tell
Org to use radio buttons for this list only.

*** Numeric priorities are now allowed (up to 65)

You can now set ~org-priority-highest/lowest/default~ to integers to
use numeric priorities globally or set, for example

#+PRIORITIES: 1 10 5

to define a buffer-local range and default for priorities.  Priority
commands should work as usual.  You cannot use numbers superior to 64
for numeric priorities, as it would clash with priorities like [#A]
where the "A" is internally converted to its numeric value of 65.

*** Property drawers allowed before first headline

Property drawers are now allowed before the first headline.

Org mode is moving more towards making things before the first
headline behave just as if it was at outline level 0.  Inheritance for
properties will work also for this level.  In other words: defining
things in a property drawer before the first headline will make them
"inheritable" for all headlines.

*** Refinement in window behavior on exiting Org source buffer

After editing a source block, Org will restore the window layout when
~org-src-window-setup~ is set to a value that modifies the layout.

*** Display remote inline images

Org now knows how to display remote images inline.

Whether the images are actually displayed is controlled by the new
option ~org-display-remote-inline-images~.

*** New option to resolve open clock at a provided time

~org-resolve-clocks~ now has a `t' option, which works just like the
`k' option, but the user specifies a time of day, not a number of
minutes.

*** New step value =semimonth= accepted for clock tables

*** Allow text rescaling in column view

You can now use =C-x C-+= in column view: the columns face size will
increase or decrease, together with the column header size.

*** New startup option =#+startup: num=

When this startup option is set, display headings as numerated.

Use =#+startup: nonum= to turn this off.

*** New tool for custom links

Org provides a new tool ~org-link-open-as-file~, useful when defining
new link types similar to "file"-type links.  See docstring for
details.

*** New optional numeric argument for ~org-return~

In situations where ~org-return~ calls ~newline~, multiple newlines
can now be inserted with this prefix argument.

*** New source code block header argument =:file-mode=

Source code block header argument =:file-mode= can set file
permissions if =:file= argument is provided.

*** =ob-C.el= allows the inclusion of non-system header files

In C and C++ blocks, ~:includes~ arguments that do not start with a
~<~ character will now be formatted as double-quoted ~#include~
statements.

*** =ob-clojure.el= supports inf-clojure.el and ClojureScript evaluation

You can now set ~(setq org-babel-clojure-backend 'inf-clojure)~ and
evaluate Clojure source blocks using [[https://github.com/clojure-emacs/inf-clojure][inf-clojure]].  With a header
argument like =:alias "alias"= the Clojure REPL will boot with
=clojure -Aalias=.  Otherwise Clojure will boot with =lein=, =boot= or
=tools.deps=, depending on whether the current directory contains a
=project.clj=, =build.boot= or =deps.edn=, falling back on
~inf-clojure-generic-cmd~ in case no such file is present.

Also, when using [[https://github.com/clojure-emacs/cider][cider]], you can now use =#+begin_src clojurescript= to
execute ClojureScript code from Org files.  Note that this works only
if your Org file is associated with a cider session that knows how to
run ClojureScript code.  A bare =lein repl= session outside of a
directory configured for ClojureScript will /not/ work.

*** =ob-java.el= supports Java command line arguments

Babel Java blocks recognize header argument =:cmdargs= and pass its
value in call to =java=.

*** =ob-screen.el= now accepts =:screenrc= header argument

Screen blocks now recognize the =:screenrc= header argument and pass
its value to the screen command via the "-c" option. The default
remains =/dev/null= (i.e. a clean screen session)

*** =ob-plantuml=: now supports using PlantUML executable to generate diagrams

Set =org-plantuml-exec-mode= to ='plantuml= in order to use the
executable instead of JAR. When using an executable it is also
possible to configure executable location as well as arguments via:
=org-plantuml-executable-path= and =org-plantuml-executable-args=.

** New commands
*** ~org-table-header-line-mode~

Turn on a minor mode to display the first data row of the table at
point in the header-line when the beginning of the table is invisible.

*** ~org-agenda-ctrl-c-ctrl-c~

Hitting =<C-c C-c>= in an agenda view now calls ~org-agenda-set-tags~.

*** ~org-hide-entry~

This command is the counterpart of ~org-show-entry~.

*** ~org-columns-toggle-or-columns-quit~

=<C-c C-c>= bound to ~org-columns-toggle-or-columns-quit~ replaces the
recent ~org-columns-set-tags-or-toggle~.  Tag setting is still
possible via column view value edit or with =<C-c C-q>=.

*** ~org-datetree-find-month-create~

Find or create a month entry for a date.

** New options and settings
*** New option ~org-html-prefer-user-labels~

When non-nil, use =NAME= affiliated keyword, or raw target values, to
generate anchor's ID.  Otherwise, consistently use internal naming
scheme.

=CUSTOM_ID= values are still always used, when available.
*** New option for using tabs in ~org-agenda-window-setup~

Choosing ~other-tab~ for ~org-agenda-window-setup~ will open the
agenda view in a new tab.  This will work with versions of Emacs since
27.1 when ~tab-bar-mode~ was introduced.

*** New option ~org-table-header-line-p~

Setting this option to =t= will activate ~org-table-header-line-mode~
in org-mode buffers.

*** New option ~org-startup-numerated~

When this option is =t=, Org files will start using ~(org-num-mode 1)~
and headings will be visually numerated.

You can turn this on/off on a per-file basis with =#+startup: num= or
=#+startup: nonum=.

*** New option ~org-clock-auto-clockout-timer~

When this option is set to a number and the user configuration
contains =(org-clock-auto-clockout-insinuate)=, Org will clock out the
currently clocked in task after that number of seconds of idle time.

This is useful when you often forget to clock out before being idle
and don't want to have to manually set the clocking time to take into
account.

*** New option to group captured datetime entries by month

A new `:tree-type month' option was added to org-capture-templates to
group new datetime entries by month.

*** New option to show source buffers using "plain" display-buffer

There is a new option ~plain~ to ~org-src-window-setup~ to show source
buffers using ~display-buffer~.  This allows users to control how
source buffers are displayed by modifying ~display-buffer-alist~ or
~display-buffer-base-action~.

*** New option ~org-archive-subtree-save-file-p~

Archiving a subtree used to always save the target archive buffer.
Commit [[git::b186d1d7][b186d1d7]] changed this behavior by always not saving the target
buffer, because batch archiving from agenda could take too much time.

This new option ~org-archive-subtree-save-file-p~ defaults to the
value =from-org= so that archiving a subtree will save the target
buffer when done from an org-mode buffer, but not from the agenda.
You can also set this option to =t= or to =from-agenda=.

*** New option ~org-show-notification-timeout~

This option will add a timeout to notifications.

*** New option ~org-latex-to-html-convert-command~

This new option allows you to convert a LaTeX fragment directly into
HTML.

*** New option ~org-babel-shell-results-defaults-to-output~

By default, source code blocks are executed in "functional mode": it
means that the results of executing them are the value of their last
statement (see [[https://orgmode.org/manual/Results-of-Evaluation.html][the documentation]].)

The value of a shell script's execution is its exit code.  But most
users expect the results of executing a shell script to be its output,
not its exit code.

So we introduced this option, that you can set to nil if you want to
stick using ~:results value~ as the implicit header.

In all Babel libraries, the absence of a ~:results~ header should
produce the same result than setting ~:results value~, unless there is
an option to explicitly create an exception.

See [[msg:CA+A2iZaziAfMeGpBqL6qGrzrWEVvLvC0DUw++T4gCF3NGuW-DQ@mail.gmail.com][this thread]] for more context.

*** New option in ~org-attach-store-link-p~

~org-attach-store-link-p~ has a new option to store a file link to the
attachment.
*** New option ~org-fontify-todo-headline~

This feature is the same as ~org-fontify-done-headline~, but for TODO
headlines instead.  This allows you to distinguish TODO headlines from
normal headlines.  The face can be customized via ~org-headline-todo~.

*** New default value for ~org-file-apps~

The new value uses Emacs as the application for opening directory.

*** New hook ~org-agenda-filter-hook~

Functions in this hook are run after ~org-agenda-filter~ is called.

** Removed or renamed functions and variables
*** Deprecated ~org-flag-drawer~ function

Use ~org-hide-drawer-toggle~ instead.

*** Deprecated ~org-hide-block-toggle-maybe~ function

Use ~org-hide-block-toggle~ instead.

*** Deprecated ~org-hide-block-toggle-all~ function

This function was not used in the code base, and has no clear use
either.  It has been marked for future removal.  Please contact the
mailing list if you use this function.

*** Deprecated ~org-return-indent~ function

In Elisp code, use ~(org-return t)~ instead.  Interactively, =C-j= is
now bound to ~org-return-and-maybe-indent~, which indents the new line
when ~electric-indent-mode~ is disabled.

*** Removed ~org-maybe-keyword-time-regexp~

The variable was not used in the code base.

*** Removed ~org-export-special-keywords~

The variable was not used in the code base.

*** Renamed ~org-at-property-block-p~

The new name is ~org-at-property-drawer-p~, which is less confusing.

*** Renamed ~org-columns-set-tags-or-toggle~

See [[*~org-columns-toggle-or-columns-quit~]].

*** Renamed priority options

From ~org-lowest-priority~ to ~org-priority-lowest~.
From ~org-default-priority~ to ~org-priority-default~.
From ~org-highest-priority~ to ~org-priority-highest~.
From ~org-enable-priority-commands~ to ~org-priority-enable-commands~.
From ~org-show-priority~ to ~org-priority-show~.

** Miscellaneous
*** =ob-screen.el= now respects screen =:session= name

Screen babel session are now named based on the =:session= header
argument (defaults to ~default~).

Previously all session names had  ~org-babel-session-~ prepended.

*** Forward/backward paragraph functions in line with the rest of Emacs

~org-forward-paragraph~ and ~org-backward-paragraph~, bound to
~<C-UP>~ and ~<C-DOWN>~ functions mimic more closely behavior of
~forward-paragraph~ and ~backward-paragraph~ functions when
available.

They also accept an optional argument for multiple calls.

See their docstring for details.
*** ~org-table-to-lisp~ no longer checks if point is at a table

The caller is now responsible for the check.  It can use, e.g.,
~org-at-table-p~.

The function is also much more efficient than it used to be, even on
very large tables.

*** New function ~org-collect-keywords~
*** Drawers' folding use an API similar to block's

Tooling for folding drawers interactively or programmatically is now
on par with block folding.  In particular, ~org-hide-drawer-toggle~,
a new function, is the central place for drawer folding.

*** Duration can be read and written in compact form

~org-duration-to-minutes~ understands =1d3h5min= as a duration,
whereas ~org-duration-from-minutes~ can output this compact form if
the duration format contains the symbol ~compact~.

*** C-n, C-p, SPC and DEL in agenda commands dispatch window

You can now use =<C-n>=, =<C-p>=, =<SPC>= and =<DEL>= key to scroll up
and down the agenda and attach dispatch window.

*** =<C-c C-c>= in agenda calls ~org-agenda-set-tags~

Both =<C-c C-q>= and =<C-c C-c>= set the tags of the headline in the
Org buffer.  Both keybindings are now available from the agenda too.

*** Allow to use an empty HTML extension

Using =(setq org-html-extension "")= or setting the HTML extension in
any fashion will produce the expected output, with no trailing period
to the resulting HTML file.

*** Handle repeated tasks with =.+= type and hours step

A task using a =.+= repeater and hours step is repeated starting from
now. E.g.,

#+begin_example
,,** TODO Wash my hands
   DEADLINE: <2019-04-05 08:00 Sun .+1h>
   Marking this DONE shifts the date to exactly one hour from now.
#+end_example

*** The format of equation reference in HTML export can now be specified

By default, HTML (via MathJax) and LaTeX export equation references
using different commands. LaTeX must use ~\ref{%s}~ because it is used
for all labels; however, HTML (via MathJax) uses ~\eqref{%s}~ for
equations producing inconsistent output. New option
~org-html-equation-reference-format~ sets the command used in HTML
export.

*** =ob-haskell.el= supports compilation with =:compile= header argument

By default, Haskell blocks are interpreted. By adding =:compile yes=
to a Haskell source block, it will be compiled, executed and the
results will be displayed.

*** Support for ~org-edit-special~ with LaTeX fragments

Calling ~org-edit-special~ on an inline LaTeX fragment calls a new
function, ~org-edit-latex-fragment~. This functions in a comparable
manner to editing inline source blocks, bringing up a minibuffer set
to LaTeX mode. The math-mode deliminators are read only.

*** ~org-capture-current-plist~ is now accessible during ~org-capture-mode-hook~
*** New =org-refile.el= file

Org refile variables and functions have been moved to a new file.

*** The end of a 7 years old bug

This bug [[https://lists.gnu.org/archive/html/emacs-orgmode/2013-08/msg00072.html][originally reported]] by Matt Lundin and investigated by Andrew
Hyatt has been fixed.  Thanks to both of them.

* Version 9.3

** Incompatible changes
*** Change bracket link escaping syntax

Org used to percent-encode sensitive characters in the URI part of the
bracket links.

Now, escaping mechanism uses the usual backslash character, according
to the following rules:

1. All =[= and =]= characters in the URI must be escaped;
2. Every =\= character preceding either =[= or =]= must be escaped;
3. Every =\= character at the end of the URI must be escaped.

When in doubt, use the function ~org-link-escape~ in order to turn
a link string into its properly escaped form.

The following function will help switching your links to the new
syntax:

#+begin_src emacs-lisp
(defun org-update-link-syntax (&optional no-query)
  "Update syntax for links in current buffer.
Query before replacing a link, unless optional argument NO-QUERY
is non-nil."
  (interactive "P")
  (org-with-point-at 1
    (let ((case-fold-search t))
      (while (re-search-forward "\\[\\[[^]]*?%\\(?:2[05]\\|5[BD]\\)" nil t)
        (let ((object (save-match-data (org-element-context))))
          (when (and (eq 'link (org-element-type object))
                     (= (match-beginning 0)
                        (org-element-property :begin object)))
            (goto-char (org-element-property :end object))
            (let* ((uri-start (+ 2 (match-beginning 0)))
                   (uri-end (save-excursion
                              (goto-char uri-start)
                              (re-search-forward "\\][][]" nil t)
                              (match-beginning 0)))
                   (uri (buffer-substring-no-properties uri-start uri-end)))
              (when (or no-query
                        (y-or-n-p
                         (format "Possibly obsolete URI syntax: %S.  Fix? "
                                 uri)))
                (setf (buffer-substring uri-start uri-end)
                      (org-link-escape (org-link-decode uri)))))))))))
#+end_src

The old ~org-link-escape~ and ~org-link-unescape~ functions have been
renamed into ~org-link-encode~ and ~org-link-decode~.

*** Change match group number in ~org-link-bracket-re~

Link description, if any, is located in match group 2 instead of match
group 3.

*** ob-clojure does not auto prepend ~(ns ..)~ statement anymore

When tangling, user usually just wants to tangle literally code instead
of prepend inserting a ~(ns ..)~ statement before source block
code.  Now, when you have no ~:ns~ header argument specified, this
behavior will not happen automatically.

*** Change in behavior on exit from an Org edit buffer

Org will no longer attempt to restore the window configuration in the
frame to which the user returns after editing a source block with
~org-edit-src-code~.  Instead, the window configuration will remain as
it is.

*** Change default value for ~org-email-link-description-format~

When linking from a mail buffer, Org used to truncate the subject of
the message to 30 characters in order to build the description of the
link.  This behavior was considered as too surprising.  As
a consequence, Org no longer truncates subjects.

You can get the old behavior back with the following:

: (setq org-email-link-description-format "Email %c: %.30s")

*** ~:file~ header argument no longer assume "file" ~:results~

The "file" ~:results~ value is now mandatory for a code block
returning a link to a file.  The ~:file~ or ~:file-ext~ header
arguments no longer imply a "file" result is expected.

*** Plain numbers are hours in Column View mode

See [[git:3367ac9457]] for details.

*** All LaTeX preview backends use now xcolor

The dvipng backend was previously relying on fg and bg parameters to
be passed to the CLI. This didn't work when xcolor was directly or
indirectly used in the document (e.g. tkiz is a user of xcolor). Since
every other backend was already using xcolor to set fg and bg, the CLI
alternative was removed and there is no more a :use-xcolor options
since now it's implicitly always true.

*** Org-Attach Git commit

[[*Org-Attach has been refactored and extended][Refactoring of Org-Attach]] affected the Git commit functionality.  Not
much, but the following changes are required if you still need to
auto-commit attachments to git:

- Customization of ~org-attach-annex-auto-get~ needs to be renamed to
  ~org-attach-git-annex-auto-get~.

- Customization of ~org-attach-commit~ is no longer needed.  Instead
  one need to require the =org-attach-git= module in the startup.

** New features
*** New option to wrap source code lines in HTML export

When new option ~html-wrap-src-lines~ (with variable
~org-html-wrap-src-lines~) is non-nil, HTML export wraps source code
lines in HTML ~code~ elements.

*** New option to handle schedules and deadlines in iCalendar export

Export ignore done tasks with a deadline when
~org-icalendar-use-deadline~ contains ~event-if-todo-not-done~.
Likewise, scheduled done tasks are also ignored when
~org-icalendar-use-scheduled~ contains the same symbol.

*** Add ~split-window-right~ option for src block edit window placement

Given the increasing popularity of wide screen monitors, splitting
horizontally may make more sense than splitting vertically.  An
option, ~split-window-right~, to request horizontal splitting has been
added to ~org-src-window-setup~.

*** Org-Attach has been refactored and extended

Org attach has been refactored and the functionality extended.  It
should now be easier to understand how it works.  A few improvements
and extra options have been added as well.

From the initial comment in org-attach source-code:

- Attachments are managed either by using a custom property DIR or by
  using property ID from org-id.  When DIR is defined, a location in
  the filesystem is directly attached to the outline node.  When
  org-id is used, attachments are stored in a folder named after the
  ID, in a location defined by ~org-attach-id-dir~.  DIR has
  precedence over ID when both parameters are defined for the current
  outline node (also when inherited parameters are taken into
  account).

From now on inheritance requires no extra property and will adhere to
~org-attach-use-inheritance~ by default.  Inheritance can be
customized to always be activated or never be activated in
~org-attach-use-inheritance~.

The ATTACH_DIR property is deprecated in favor of the shorter
property DIR.  Links to folders inside the DIR property can now be
declared as relative links.  This is not enabled by default, but can
be set in ~org-attach-dir-relative~.

When adding new attachment to the outline node the preferred way of
doing so can be customized.  Take a look at
~org-attach-preferred-new-method~.  It defaults to using ID since that
was the behavior before this change.

If both DIR and ID properties are set on the same node, DIR has
precedence and will be used.

One can now also choose to build attachment-directory-paths in a
customized way.  This is an advanced topic, but in some case it makes
sense to parse an ID in a different way than the default one.  Create
your own function and add it to the beginning of
~org-attach-id-to-path-function~list~ if you want to customize the ID
based folder structure.

If you've used ATTACH_DIR properties to manage attachments, use the
following code to rename that property to DIR which supports the same
functionality.  ATTACH_DIR_INHERIT is no longer supported and is
removed.

#+begin_src emacs-lisp
  (defun org-update-attach-properties ()
      "Change properties for Org-Attach."
      (interactive)
      (org-with-point-at 1
	(while (outline-next-heading)
	  (let ((DIR (org--property-local-values "ATTACH_DIR" nil)))
	    (when DIR
	      (org-set-property "DIR" (car DIR))
	      (org-delete-property "ATTACH_DIR"))))
	(org-delete-property-globally "ATTACH_DIR_INHERIT")))
#+end_src

For those who hate breaking changes, even though the changes are made
to clean things up; fear not.  ATTACH_DIR will still continue to work.
It's just not documented any longer.  When you get the chance, run the
code above to clean things up anyway!

**** New hooks
Two hooks are added to org-attach:
- org-attach-after-change-hook
- org-attach-open-hook

They are added mostly for internal restructuring purposes, but can
ofc. be used for other things as well.

*** New link-type: Attachment

Attachment-links are now first-class citizens.  They mimic file-links
in everything they do but use the existing attachment-folder as a base
when expanding the links. Both =DIR= and =ID= properties are used to
try to resolve the links, in exactly the same way as Org-Attach uses
those properties.

*** Handle overlay specification for notes in Beamer export

This aligns Beamer notes with slide overlays.

*** Add support for lettered lists in Texinfo

Using =:enum A= or =:enum a= Texinfo attribute switches an otherwise
numbered list to a lettered list.

*** Add a dispatcher command to insert dynamic blocks

You can add new dynamic blocks with function
~org-dynamic-block-define~.  All such dynamic blocks can be used by
~org-dynamic-block-insert-dblock~ command.

*** Babel

**** ob-emacs-lisp sets ~lexical-binding~ in Org edit buffers

When editing an Elisp src block, the editing buffer's
~lexical-binding~ is set according to the src block's =:lexical=
parameter.

**** Add LaTeX output support in PlantUML

*** New minor mode to display headline numbering

Use =<M-x org-num-mode>= to get a visual indication of the numbering
in the outline.  The numbering is also automatically updated upon
changes in the buffer.

*** New property =HTML_HEADLINE_CLASS= in HTML export

The new property =HTML_HEADLINE_CLASS= assigns a class attribute to
a headline.

*** Allow LaTeX attributes and captions for "table.el" tables

Supported LaTeX attributes are ~:float~, ~:center~, ~:font~ and
~:caption~.

*** Attach buffer contents to headline

With =<b>= key from attachment dispatcher (=<C-c C-a>=), it is now
possible to write the contents of a buffer to a file in the headline
attachment directory.

*** iCalendar export respects a =CLASS= property

Set the =CLASS= property on an entry to specify a visibility class for
that entry only during iCalendar export. The property can be set to
anything the calendar server supports. The iCalendar standard defines
the values =PUBLIC=, =CONFIDENTIAL=, =PRIVATE=, which can be
interpreted as publicly visible, accessible to a specific group, and
private respectively.

This property can be inherited during iCalendar export, depending on
the value of ~org-use-property-inheritance~.

*** New parameter for =INCLUDE= keyword

Add =:coding CODING-SYSTEM= to include files using a different coding
system than the main Org document.  For example:

#+begin_example
,#+INCLUDE: "myfile.cmd" src cmd :coding cp850-dos
#+end_example

*** New values in clock tables' step: =month= and =year=
*** ODT export handles numbers cookies in lists
*** New cell movement functions in tables

~S-<UP>~, ~S-<DOWN>~, ~S-<RIGHT>~, and ~S-<LEFT>~ now move cells in
the corresponding direction by swapping with the adjacent cell.

*** New option to natively fontify LaTeX snippets and environments

A 'native option was added to org-highlight-latex-and-related. It
matches the same structures than 'latex but it calls
org-src-font-lock-fontify-block instead, thus bringing about full
LaTeX font locking.

*** ~org-clone-subtree-with-time-shift~ learned to shift backward in time

=<C-c C-x c>= (~org-clone-subtree-with-time-shift~) now takes a
negative value as a valid repeater to shift time stamps in backward
in cloned subtrees.  You can give, for example, ‘-3d’ to shift three
days in the past.

*** Toggle display of all vs. undone scheduled habits conveniently

=<C-u K>= (~org-habit-toggle-display-in-agenda~) in an agenda toggles
the display of all habits to those which are undone and scheduled.
This is a function for convenience.

*** New parameter for SQL Babel blocks: ~:dbconnection~

The new parameter ~:dbconnection~ allows to specify a connection name
in a SQL block header: this name is used to look up connection
parameters in ~sql-connection-alist~.

*** New =:scale= attribute supported by LaTeX exporters

The builtin "latex" exporters now accept and use a =:scale= attribute,
which scales an image by a given factor.

This attribute is wrapped around the =scale= parameter of LaTeX's
=\includegraphics= (bitmap images) or a TiKZ's =\scalebox=.
Therefore, its value should be some string palatable to LaTeX as
a positive float Its default value is an empty string (i.e. disabled).

This attribute overrides the =:width= and =:height= attributes.

#+begin_example
,#+name: Beastie
,#+caption: I think I saw this curious horse already, but where ?
,#+LATEX_ATTR: :scale 2
[[https://orgmode.org/img/org-mode-unicorn-logo.png]]
#+end_example

*** Allow specifying the target for a table of contents

The =+TOC= keyword now accepts a =:target:= attribute that specifies
the headline to use for making the table of contents.

#+begin_example
,* Target
  :PROPERTIES:
  :CUSTOM_ID: TargetSection
  :END:
,** Heading A
,** Heading B
,* Another section
,#+TOC: headlines 1 :target "#TargetSection"
#+end_example

** New functions
*** ~org-dynamic-block-insert-dblock~

Use default keybinding =<C-c C-x x>= to run command
~org-dynamic-block-insert-dblock~.  It will prompt user to select
dynamic block in ~org-dynamic-block-alist~.

*** ~org-table-cell-up~
*** ~org-table-cell-down~
*** ~org-table-cell-left~
*** ~org-table-cell-right~
*** ~org-habit-toggle-display-in-agenda~
** Removed functions and variables
*** Removed Org Drill

You can install it back from MELPA.

*** ~org-babel-set-current-result-hash~
*** ~org-capture-insert-template-here~
*** ~org-attach-directory~

It has been deprecated in favor of ~org-attach-id-dir~ which is less
ambiguous given the restructured org-attach.

*** ~org-enable-fixed-width-editor~

This variable was not used through the code base.

** Miscellaneous
*** Change signature for ~org-list-to-subtree~

The function now accepts the level of the subtree as an optional
argument.  It no longer deduces it from the current level.

*** LaTeX preview is simplified

Function ~org-latex-preview~, formerly known as
~org-toggle-latex-fragment~, has a hopefully simpler and more
predictable behavior.  See its docstring for details.

*** ~org-table-copy-down~ supports patterns

When ~org-table-copy-increment~ is non-nil, it is now possible to
increment fields like =A1=, or =0A=, i.e., any string prefixed or
suffixed with a whole number.

*** No more special indentation for description items

Descriptions items are indented like regular ones, i.e., text starts
after the bullet.  Special indentation used to introduce bugs when
inserting sub-items in a description list.

*** New hook: ~org-todo-repeat-hook~

This hook was actually introduced in Org 9.2.1, but wasn't advertised.

*** Org Table reads numbers starting with 0 as strings
*** Disable fast tag selection interface via prefix arg

A call of ~org-set-tags-command~ with prefix argument C-u C-u avoids
the fast tag selection interface and instead offers the plain
interface.

*** ~:mkdirp~ now supports create directory for ~:dir~ path

The ~:mkdirp~ header argument used to only work for ~:tangle~ tangle
files. Now ~:mkdirp~ works for ~:dir~ too. This is more convenient for
specify default directory and with ~:file~ header argument.

*** New variable: ~org-agenda-breadcrumbs-separator~

If breadcrumbs are showed in org-agenda with the help of "%b" format
in ~org-agenda-prefix-format~, user can customize breadcrumbs's
separator using ~org-agenda-breadcrumbs-separator~.

*** New variable ~org-attach-commands~

This variable makes it possible to customize the list of commands for
the attachment dispatcher.

*** New ID method based on timestamp

If one chooses, it is now possible to create ID's based on timestamp
(ISO8601) instead of UUID by changing org-id-method to ts.

For an improved folder structure when using timestamp as ID, make sure
to promote ~org-attach-id-ts-folder-format~ to the first element of
~org-attach-id-to-path-function-list~ in your configuration at the
same time.

*** New customization: ~org-id-locations-relative~

New customization to make the persisting of org-id-locations between
sessions to store links to files as relative instead of absolute.  The
links will be stored as relative to the path of org-id-locations-file.

*** ~org-ctrl-c-tab~ is functional before the first headline

I.e. treat the whole file as if it was a subtree.

Also fold everything below the chosen level.  Former behavior was to
leave unfolded subtrees unfolded.

*** ~org-kill-note-or-show-branches~ is functional before the first headline

I.e. treat the whole file as if it was a subtree.

*** Respect narrowing when agenda command is restricted to buffer

*** ~org-table-insert-column~ inserts the column at point position

Before, the new column was inserted to the right of the column at
point position.

*** Table column deletion now consistent with row deletion

Point stays in the column at deletion, except when deleting the
rightmost column.

* Version 9.2
** Incompatible changes
*** Removal of OrgStruct mode mode and radio lists

OrgStruct minor mode and radio lists mechanism (~org-list-send-list~
and ~org-list-radio-lists-templates~) are removed from the code base.

Note that only radio /lists/ have been removed, not radio tables.

If you want to manipulate lists like in Org in other modes, we suggest
to use =orgalist.el=, which you can install from GNU ELPA.

If you want to use Org folding outside of Org buffers, you can have a
look at the outshine package in the MELPA repository.

*** Change in the structure template expansion

Org 9.2 comes with a new template expansion mechanism, combining
~org-insert-structure-template~ bound to ~C-c C-,~.

If you customized the ~org-structure-template-alist~ option manually,
you probably need to update it, see the docstring for accepted values.

If you prefer using previous patterns, e.g. =<s=, you can activate
them again by requiring Org Tempo library:

: (require 'org-tempo)

or add it to ~org-modules~.

If you need complex templates, look at the ~tempo-define-template~
function or at solutions like Yasnippet.

*** Change to Noweb expansion

Expansion check =:noweb-ref= only if no matching named block is found
in the buffer.  As a consequence, any =:noweb-ref= value matching the
name of a source block in the buffer is ignored. A simple fix is to
give every concerned source-block, including the named one, a new,
unique, Noweb reference.

#+BEGIN_SRC org
  ,#+NAME: foo
  ,#+BEGIN_SRC emacs-lisp
    1
  ,#+END_SRC

  ,#+BEGIN_SRC emacs-lisp :noweb-ref foo
    2
  ,#+END_SRC

  ,#+BEGIN_SRC emacs-lisp :noweb yes
    <<foo>>
  ,#+END_SRC
#+END_SRC

should become

#+BEGIN_SRC org
  ,#+NAME: foo
  ,#+BEGIN_SRC emacs-lisp :noweb-ref bar
    1
  ,#+END_SRC

  ,#+BEGIN_SRC emacs-lisp :noweb-ref bar
    2
  ,#+END_SRC

  ,#+BEGIN_SRC emacs-lisp :noweb yes
    <<bar>>
  ,#+END_SRC
#+END_SRC

*** Default/accepted values of ~org-calendar-to-agenda-key~

The default value and accepted value of  ~org-calendar-to-agenda-key~
changed.  This is an excerpt of the new docstring:

: When set to ‘default’, bind the function to ‘c’, but only if it is
: available in the Calendar keymap.  This is the default choice because
: ‘c’ can then be used to switch back and forth between agenda and calendar.
:
: When nil, ‘org-calendar-goto-agenda’ is not bound to any key.

Check the full docstring for more.

*** Change the signature of the ~org-set-effort~ function

Here is the new docstring:

: (org-set-effort &optional INCREMENT VALUE)
:
: Set the effort property of the current entry.
: If INCREMENT is non-nil, set the property to the next allowed
: value.  Otherwise, if optional argument VALUE is provided, use
: it.  Eventually, prompt for the new value if none of the previous
: variables is set.

*** Placeholders in =(eval ...)= macros are always strings

Within =(eval ...)= macros, =$1=-like placeholders are always replaced
with a string.  As a consequence, they must not be enclosed within
quotes. As an illustration, consider the following, now valid,
examples:

#+begin_example
  ,#+macro: join (eval (concat $1 $2))
  ,#+macro: sum (eval (+ (string-to-number $1) (string-to-number $2)))

  {{{join(a,b)}}} => ab
  {{{sum(1,2)}}}  => 3
#+end_example

However, there is no change in non-eval macros:

#+begin_example
  ,#+macro: disp argument: $1

  {{{disp(text)}}} => argument: text
#+end_example

*** =align= STARTUP value no longer narrow table columns

Columns narrowing (or shrinking) is now dynamic. See [[*Dynamically
narrow table columns]] for details. In particular, it is decoupled from
aligning.

If you need to automatically shrink columns upon opening an Org
document, use =shrink= value instead, or in addition to align:

#+BEGIN_EXAMPLE
,#+STARTUP: align shrink
#+END_EXAMPLE

*** ~org-get-tags~ meaning change

Function ~org-get-tags~ used to return local tags to the current
headline.  It now returns all the inherited tags in addition to the
local tags.  In order to get the old behavior back, you can use:

: (org-get-tags nil t)

*** Alphabetic sorting in tables and lists

When sorting alphabetically, ~org-table-sort-lines~ and ~org-sort-list~
now sort according to the locale’s collation rules instead of by
code-point.

*** Change the name of the :tags clocktable option to :match

The =:match= (renamed from =:tags=) option allows to limit clock entries
to those matching a todo-tags matcher.

The old =:tags= option can be set to =t= to display a headline's tags in a
dedicated column.

This is consistent with the naming of =org-dblock-write:columnview=
options, where =:match= is also used as a headlines filter.

** New features
*** Add ~:session~ support of ob-clojure for CIDER
You can initialize source block session with Babel default keybinding
=[C-c C-v C-z]= to use =sesman= session manager to link current
project, directory or buffer with specific Clojure session, or
=cider-jack-in= a new CIDER REPL if no CIDER REPLs available. In older
CIDER version which has not =sesman= integrated, only has
=cider-jack-in= without Clojure project is supported.
#+begin_src clojure :session
(dissoc Clojure 'JVM)
(conj clojurists "stardiviner")
#+end_src

*** Add ~:results link~ support for Babel

With this output format, create a link to the file specified in
~:file~ header argument, without actually writing any result to it:

#+begin_example
,#+begin_src shell :dir "data/tmp" :results link :file "crackzor_1.0.c.gz"
wget -c "https://ben.akrin.com/crackzor/crackzor_1.0.c.gz"
,#+end_src

,#+results:
[[file:data/tmp/crackzor_1.0.c.gz]]
#+end_example

*** Add ~:session~ support of ob-js for js-comint
#+begin_src js :session "*Javascript REPL*"
console.log("stardiviner")
#+end_src

*** Add ~:session~ support of ob-js for Indium
#+begin_src js :session "*JS REPL*"
console.log("stardiviner")
#+end_src

*** Add ~:session~ support of ob-js for skewer-mode
#+begin_src js :session "*skewer-repl*"
console.log("stardiviner")
#+end_src

*** Add support for links to LaTeX equations in HTML export
Use MathJax links when enabled (by ~org-html-with-latex~), otherwise
add a label to the rendered equation.
*** Org Tempo may used for snippet expansion of structure template.
See manual and the commentary section in ~org-tempo.el~ for details.
*** Exclude unnumbered headlines from table of contents
Set their =UNNUMBERED= property to the special =notoc= value.  See
manual for details.
*** ~org-archive~ functions update status cookies

Archiving headers through ~org-archive-subtree~ and
~org-archive-to-archive-sibling~ such as the ones listed below:

#+BEGIN_SRC org
  ,* Top [1/2]
  ,** DONE Completed
  ,** TODO Working
#+END_SRC

Will update the status cookie in the top level header.

*** Disable =org-agenda-overriding-header= by setting to empty string

The ~org-agenda-overriding-header~ inserted into agenda views can now
be disabled by setting it to an empty string.

*** Dynamically narrow table columns

With ~C-c TAB~, it is now possible to narrow a column to the width
specified by a width cookie in the column, or to 1 character if there
is no such cookie.  The same keybinding expands a narrowed column to
its previous state.

Editing the column automatically expands the whole column to its full
size.

*** =org-columns-summary-types= entries can take an optional COLLECT function

You can use this to make collection of a property from an entry
conditional on another entry. E.g. given this configuration:

#+BEGIN_SRC emacs-lisp
  (defun custom/org-collect-confirmed (property)
    "Return `PROPERTY' for `CONFIRMED' entries"
    (let ((prop (org-entry-get nil property))
	  (confirmed (org-entry-get nil "CONFIRMED")))
      (if (and prop (string= "[X]" confirmed))
	  prop
	"0")))

  (setq org-columns-summary-types
	'(("X+" org-columns--summary-sum
	   custom/org-collect-confirmed)))
#+END_SRC

You can have a file =bananas.org= containing:

#+BEGIN_SRC org
  ,#+columns: %ITEM %CONFIRMED %Bananas{+} %Bananas(Confirmed Bananas){X+}

  ,* All shipments
  ,** Shipment 1
     :PROPERTIES:
     :CONFIRMED: [X]
     :Bananas:  4
     :END:

  ,** Shipment 2
     :PROPERTIES:
     :CONFIRMED: [ ]
     :BANANAS:  7
     :END:
#+END_SRC

... and when going to the top of that file and entering column view
you should expect to see something like:

| ITEM          | CONFIRMED | Bananas | Confirmed Bananas |
|---------------+-----------+---------+-------------------|
| All shipments |           |      11 |                 4 |
| Shipment 1    | [X]       |       4 |                 4 |
| Shipment 2    | [ ]       |       7 |                 7 |

#+BEGIN_EXAMPLE
  ,#+STARTUP: shrink
#+END_EXAMPLE

*** Allow to filter by tags/property when capturing colview

You can now use =:match= to filter entries using a todo/tags/properties
matcher.

*** Add support for Oracle's database alias in Babel blocks
=ob-sql= library already support running SQL blocks against an Oracle
database using ~sqlplus~.  Now it's possible to use alias names
defined in =TNSNAMES= file instead of specifying full connection
parameters.  See example below.

#+BEGIN_SRC org
  you can use the previous full connection parameters
  ,#+BEGIN_SRC sql :engine oracle :dbuser me :dbpassword my_insecure_password :database my_db_name :dbhost my_db_host :dbport 1521
  select sysdate from dual;
  ,#+END_SRC

  or the alias defined in your TNSNAMES file
  ,#+BEGIN_SRC sql :engine oracle :dbuser me :dbpassword my_insecure_password :database my_tns_alias
  select sysdate from dual;
  ,#+END_SRC
#+END_SRC

*** ~org-agenda-set-restriction-lock~ toggle agenda restriction at point

You can set an agenda restriction lock with =C-x C-x <= or with =<= at the
beginning of a headline when using Org speed commands.  Now, if there
is already a restriction at point, hitting =<= again (or =C-x C-x <=) will
remove it.

*** Headlines can now link to themselves in HTML export

When enabling ~org-html-self-link-headlines~ the headlines exported to
HTML contain a hyperlink to themselves.

** New commands and functions

*** ~org-insert-structure-template~

This function can be used to wrap existing text of Org elements in
a #+BEGIN_FOO/#+END_FOO block.  Bound to C-c C-x w by default.

*** ~org-export-excluded-from-toc-p~

See docstring for details.

*** ~org-timestamp-to-time~
*** ~org-timestamp-from-string~
*** ~org-timestamp-from-time~
*** ~org-attach-dired-to-subtree~

See docstring for details.

*** ~org-toggle-narrow-to-subtree~

Toggle the narrowing state of the buffer: when in a narrowed state,
widen, otherwise call ~org-narrow-to-subtree~ to narrow.

This is attached to the "s" speed command, so that hitting "s" twice
will go back to the widen state.

*** ~org-browse-news~

Browse https://orgmode.org/Changes.html to let users read information
about the last major release.

There is a new menu entry for this in the "Documentation" menu item.

*** ~org-info-find-node~

From an Org file or an agenda switch to a suitable info page depending
on the context.

The function is bound to =C-c C-x I=.

** Removed commands and functions
*** ~org-outline-overlay-data~
Use ~org-save-outline-visibility~ instead.
*** ~org-set-outline-overlay-data~
Use ~org-save-outline-visibility~ instead.
*** ~org-get-string-indentation~
It was not used throughout the code base.
*** ~org-fix-indentation~
It was not used throughout code base.
*** ~org-context-p~
Use ~org-element-at-point~ instead.
*** ~org-preserve-lc~
It is no longer used in the code base.
*** ~org-try-structure-completion~
Org Tempo may be used as a replacement.  See details above.
** Removed options

*** org-babel-use-quick-and-dirty-noweb-expansion

See [[*Change to Noweb expansion][Change to Noweb expansion]] for explanations.

** Miscellaneous

*** New default value for ~org-texinfo-table-scientific-notation~

It is now nil, which means numbers in scientific notation are not
handled specially by default.

*** New default value for ~org-latex-table-scientific-notation~

It is now nil, which means numbers in scientific notation are not
handled specially by default.

*** New face: ~org-upcoming-distant-deadline~

It is meant to be used as the face for distant deadlines, see
~org-agenda-deadline-faces~

*** ~org-paste-subtree~ no longer breaks sections

Unless point is at the beginning of a headline, ~org-paste-subtree~
now pastes the tree before the next visible headline.  If you need to
break the section, use ~org-yank~ instead.

*** ~org-table-insert-column~ inserts a column to the right

It used to insert it on the left.  With this change,
~org-table-insert-column~ and ~org-table-delete-column~ are
reciprocal.

*** ~org-publish-resolve-external-link~ accepts a new optional argument.
*** ~org-irc.el~ now supports exporting =irc:= links properly

Previously, irc links were exported by ~ox-md~ and ~ox-html~ as normal
file links, which lead to them being broken in web browsers. Now both
of these exporters will properly export to =irc:= links, which will
open properly in irc clients from web browsers.

*** ~org-comment-dwim~ (bound to =M-;=) now comments headings, if point is on a heading
*** Add support for open source block in window below

Set option ~org-src-window-setup~ to ~split-window-below~.

*** Alphabetic sorting in headings and tags now uses the locale’s sorting rules

When sorting alphabetically, ~org-sort-entries~ and
~org-tags-sort-function~ now sort according to the locale’s collation
rules instead of by code-point.
*** New speed command "k" to kill (cut) the subtree at point
* Version 9.1

** Incompatible changes

*** Variables relative to clocksum duration are obsolete

~org-time-clocksum-format~, ~org-time-clocksum-use-fractional~ and
~org-time-clocksum-fractional-format~ are obsolete.  If you changed
them, consider modifying ~org-duration-format~ instead.

Variable ~org-time-clocksum-use-effort-durations~ is also obsolete.
Consider setting ~org-duration-units~ instead.

*** ~org-at-timestamp-p~ optional argument accepts different values

See docstrings for the allowed values.  For backward compatibility,
~(org-at-timestamp-p t)~ is still supported, but should be updated
accordingly.

*** ~org-capture-templates~ no longer accepts S-expressions as file names

Since functions are allowed there, a straightforward way to migrate
is to turn, e.g.,

: (file (sexp))

into

: (file (lambda () (sexp)))

*** Deleted contributed packages

=org-ebib.el, =org-bullets.el= and =org-mime.el= have been deleted
from the contrib/ directory.

You can now find them here :

- https://github.com/joostkremers/ebib
- https://github.com/sabof/org-bullets
- https://github.com/org-mime/org-mime

*** Change ~org-texinfo-classes~ value
The value cannot support functions to create sectioning commands
anymore.  Also, the sectioning commands should include commands for
appendices.  See the docstring for more information.
*** Removal of ~:sitemap-sans-extension~

The publishing property is no longer recognized, as a consequence of
changes to site-map generation.

You can get the same functionality by setting ~:sitemap-format-entry~
to the following

#+BEGIN_SRC elisp
(lambda (entry style project)
  (cond ((not (directory-name-p entry))
	 (format "[[file:%s][%s]]"
		 (file-name-sans-extension entry)
		 (org-publish-find-title entry project)))
	((eq style 'tree) (file-name-nondirectory (directory-file-name entry)))
	(t entry)))
#+END_SRC

*** Change signature for ~:sitemap-function~

~:sitemap-function~ now expects to be called with two arguments.  See
~org-publish-project-alist~ for details.

*** Change signature for some properties in ~org-list-to-generic~

~:istart~, ~:icount~, ~:iend~ and ~:isep~ now expect the type of the
list as their first argument.

*** Change signature for ~org-get-repeater~
The optional argument is now a string to extract the repeater from.
See docstring for details.

*** Change signature for ~org-time-string-to-time~
See docstring for changes.

*** Change order of items in ~org-agenda-time-grid~
~org-agenda-time-grid~ gained an extra item to allow users to customize
the string displayed after times in the agenda. See docstring for
details.

*** ~tags-todo~ custom searches now include DONE keywords

Use "/!" markup when filtering TODO keywords to get only not-done TODO
keywords.

*** ~org-split-string~ returns ~("")~ when called on an empty string

It used to return nil.

*** Removal of =ob-scala.el=

See [[https://github.com/ensime/emacs-scala-mode/issues/114][this github issue]].

You can use =ob-scala.el= as packaged in scala-mode, available from the
MELPA repository.

** New features
*** iCalendar export uses inheritance for TIMEZONE and LOCATION properties
Both these properties can be inherited during iCalendar export,
depending on the value of ~org-use-property-inheritance~.
*** iCalendar export respects a TIMEZONE property
Set the TIMEZONE property on an entry to specify a time zone for that
entry only during iCalendar export.  The property value should be
specified as in "Europe/London".
*** ~org-attach~ can move directory contents
When setting a new directory for an entry, org-attach offers to move
files over from the old directory.  Using a prefix arg will reset the
directory to old, ID based one.
*** New Org duration library
This new library implements tools to read and print time durations in
various formats (e.g., "H:MM", or "1d 2h 3min"...).

See ~org-duration-to-minutes~ and ~org-duration-from-minutes~
docstrings.

*** Agenda
**** New variable : ~org-agenda-show-future-repeats~
**** New variable : ~org-agenda-prefer-last-repeat~
**** New variable : ~org-deadline-past-days~
See docstring for details.
**** Binding C-c C-x < for ~org-agenda-set-restriction-lock-from-agenda~
**** New auto-align default setting for =org-agenda-tags-column=

=org-agenda-tags-column= can now be set to =auto=, which will
automatically align tags to the right edge of the window.  This is now
the default setting.
*** New value for ~org-publish-sitemap-sort-folders~

The new ~ignore~ value effectively allows toggling inclusion of
directories in published site-maps.

*** Babel

**** Scheme: support for tables
**** Scheme: new variable: ~org-babel-scheme-null-to~

This new custom option allows you to use an empty list or null symbol to
format the table output, initially assigned to ~hlines~.

**** Scheme: new header ~:prologue~

A new block code header has been created for Org Babel that enables
developers to prepend code to the scheme block being processed.

Multiple ~:prologue~ headers can be added each of them using a string
with the content to be added.

The scheme blocks are prepared by surrounding the code in the block
with a let form. The content of the ~:prologue~ headers are prepended
before this let form.

**** Support for hledger accounting reports added
**** Clojure: new setting ~org-babel-clojure-sync-nrepl-timeout~

Creation of a new setting to specify the Cider timeout.  By setting
the =org-babel-clojure-sync-nrepl-timeout= setting option.  The value
is in seconds and if set to nil then no timeout will occur.

**** Clojure: new header ~:show-process~

A new block code header has been created for Org Babel that enables
developers to output the process of an ongoing process into a new
window/buffer.

You can tell Org Babel to output the process of a running code block.

To show that output you only have to specify the =:show-process=
option in the code block's header like this:

#+begin_example
,#+BEGIN_SRC clojure :results output :show-process t
  (dotimes [n 10]
    (println n ".")
    (Thread/sleep 500))
,#+END_SRC
#+end_example

If =:show-process= is specified that way, then when you will run the
code using =C-c C-c= a new window will open in Emacs.  Everything that
is output by the REPL will immediately be added to that new window.

When the processing of the code is finished, then the window and its
buffer will be closed and the results will be reported in the
=#+RESULTS= section.

Note that the =:results= parameter's behavior is *not* changed.  If
=silent= is specified, then no result will be displayed.  If =output=
is specified then all the output from the window will appears in the
results section.  If =value= is specified, then only the last returned
value of the code will be displayed in the results section.

**** Maxima: new headers ~:prologue~ and ~:epilogue~
Babel options ~:prologue~ and ~:epilogue~ have been implemented for
Maxima source blocks which prepend and append, respectively, the given
code strings.  This can be useful for specifying formatting settings
which would add clutter to exported code.  For instance, you can use
this ~:prologue "fpprintprec: 2; linel: 50;"~ for presenting Maxima
results in a beamer presentation.
**** PlantUML: add support for header arguments

[[https://plantuml.com/][Plantuml]] source blocks now support the [[https://orgmode.org/manual/prologue.html#prologue][~:prologue~]], [[https://orgmode.org/manual/epilogue.html#epilogue][~:epilogue~]] and
[[https://orgmode.org/manual/var.html#var][~:var~]] header arguments.

**** SQL: new engine added ~sqsh~

A new engine was added to support ~sqsh~ command line utility for use
against Microsoft SQL Server or Sybase SQL server.

More information on ~sqsh~ can be found here: [[https://sourceforge.net/projects/sqsh/][sourceforge/sqsh]]

To use ~sqsh~ in an *sql* =SRC_BLK= set the =:engine= like this:

#+begin_example
,#+BEGIN_SRC sql :engine sqsh :dbhost my_host :dbuser master :dbpassword pass :database support
Select * From Users
Where clue > 0
,#+END_SRC
#+end_example

**** SQL: new engine added =vertica=

A new engine was added to support vsql command line utility for use
against HP Vertica.

More information on =vsql= can be found here: [[https://my.vertica.com/docs/7.2.x/HTML/index.htm#Authoring/ConnectingToHPVertica/vsql/UsingVsql.htm][my.vertica.com]]

To use =vertica= in an sql =SRC_BLK= set the =:engine= like this:

#+BEGIN_EXAMPLE
  ,#+BEGIN_SRC sql :engine vertica :dbhost my_host :dbuser dbadmin :dbpassword pw :database vmart
  SELECT * FROM nodes;
  ,#+END_SRC
#+END_EXAMPLE

**** C++: New header ~:namespaces~

The new ~:namespaces~ export option can be used to specify namespaces
to be used within a C++ org source block.  Its usage is similar to
~:includes~, in that it can accept multiple, space-separated
namespaces to use.  This header is equivalent to adding ~using
namespace <name>;~ in the source block. Here is a "Hello World" in C++
using ~:namespaces~:

#+begin_example
  ,#+BEGIN_SRC C++ :results output :namespaces std :includes <iostream>
    cout << "Hello World" << endl;
  ,#+END_SRC
#+end_example

**** Support for Vala language

[[https://wiki.gnome.org/Projects/Vala][Vala]] language blocks support two special header arguments:

- ~:flags~ passes arguments to the compiler
- ~:cmdline~ passes commandline arguments to the generated executable

Support for [[https://orgmode.org/manual/var.html#var][~:var~]] does not exist yet, also there is no [[https://orgmode.org/manual/session.html#session][~:session~]]
support because Vala is a compiled language.

The Vala compiler binary can be changed via the ~defcustom~
~org-babel-vala-compiler~.

*** New ~function~ scope argument for the Clock Table
Added a nullary function that returns a list of files as a possible
argument for the scope of the clock table.
*** Export
**** Implement vernacular table of contents in Markdown exporter
Global table of contents are generated using vanilla Markdown syntax
instead of HTML.  Also #+TOC keyword, including local table of
contents, are now supported.
**** Add Slovenian translations
**** Implement ~org-export-insert-image-links~
This new function is meant to be used in back-ends supporting images
as descriptions of links, a.k.a. image links.  See its docstring for
details.
**** New macro : ~{{{n}}}~
This macro creates and increment multiple counters in a document.  See
manual for details.
**** Add global macros through ~org-export-global-macros~
With this variable, one can define macros available for all documents.
**** New keyword ~#+EXPORT_FILE_NAME~
Similarly to ~:EXPORT_FILE_NAME:~ property, this keyword allows the
user to specify the name of the output file upon exporting the
document.  This also has an effect on publishing.
**** Horizontal rules are no longer ignored in LaTeX table math mode
**** Use ~compilation-mode~ for compilation output
**** Plain lists accept a new ~:separator~ attribute in Texinfo

The new ~:separator~ attribute splits a tag from a description list
item into multiple parts.  This allows to have two-column tables with
multiple entries in the first column.  See manual for more details.

**** ~latex-environment~ elements support ~caption~ keywords for LaTeX export
*** ~org-edit-special~ can edit LaTeX environments

Using ~C-c '~ on a LaTeX environment opens a sub-editing buffer.  By
default, major mode in that buffer is ~latex-mode~, but it can be
changed by configuring ~org-src-lang-modes~.

*** ~org-list-to-generic~ includes a new property: ~:ifmt~

~:ifmt~ is a function to be called on the body of each item.  See
~org-list-to-generic~ documentation for details.

*** New variable : ~org-bibtex-headline-format-function~
This allow to use a different title than entry title.

*** ~org-attach~ supports attaching files from URLs

Using ~C-c C-a u~ prompts for a URL pointing to a file to be attached
to the document.

*** New option for ~org-refile-use-outline-path~
~org-refile-use-outline-path~ now supports the setting ~buffer-name~,
which causes refile targets to be prefixed with the buffer’s
name. This is particularly useful when used in conjunction with
~uniquify.el~.

*** ~org-file-contents~ now allows the FILE argument to be a URL.
This allows ~#+SETUPFILE:~ to accept a URL instead of a local file
path.  The URL contents are auto-downloaded and saved to a temporary
cache ~org--file-cache~.  A new optional argument ~NOCACHE~ is added
to ~org-file-contents~.

*** ~org-mode-restart~ now resets the newly added ~org--file-cache~.
Using ~C-c C-c~ on any keyword (like ~#+SETUPFILE~) will reset the
that file cache.

*** New option : ~org-table-duration-hour-zero-padding~
This variable allow computed durations in tables to be zero-padded.

*** New mode switch for table formulas : =U=
This mode omits seconds in durations.

** Removed functions

*** Org Timeline

This feature has been removed.  Use a custom agenda view, possibly
narrowed to current buffer to achieve a similar functionality.

*** ~org-agenda-skip-entry-when-regexp-matches~ is obsolete

Use ~org-agenda-skip-if~ instead.

*** ~org-agenda-skip-subtree-when-regexp-matches~ is obsolete

Use ~org-agenda-skip-if~ instead.

*** ~org-agenda-skip-entry-when-regexp-matches-in-subtree~ is obsolete

Use ~org-agenda-skip-if~ instead.

*** ~org-minutes-to-clocksum-string~ is obsolete

Use ~org-duration-from-minutes~ instead.

*** ~org-hh:mm-string-to-minutes~ is obsolete

Use ~org-duration-to-minutes~ instead.

*** ~org-duration-string-to-minutes~ is obsolete

Use ~org-duration-to-minutes~ instead.

*** ~org-gnus-nnimap-cached-article-number~ is removed.

This function relied on ~nnimap-group-overview-filename~, which was
removed from Gnus circa September 2010.

** Removed options

*** ~org-agenda-repeating-timestamp-show-all~ is removed.

For an equivalent to a nil value, set ~org-agenda-show-future-repeats~
to nil and ~org-agenda-prefer-last-repeat~ to =t=.

*** ~org-gnus-nnimap-query-article-no-from-file~ is removed.

This variable has no effect, as it was relying on a function that was
removed from Gnus circa September 2010.

*** ~org-usenet-links-prefer-google~ is obsolete.

Use ~org-gnus-prefer-web-links~ instead.

*** ~org-publish-sitemap-file-entry-format~ is deprecated

One can provide new ~:sitemap-format-entry~ property for a function
equivalent to the removed format string.

*** ~org-enable-table-editor~ is removed.

Setting it to a nil value broke some other features (e.g., speed
keys).

*** ~org-export-use-babel~ cannot be set to ~inline-only~

The variable is now a boolean.

*** ~org-texinfo-def-table-markup~ is obsolete

Use ~org-texinfo-table-default-markup~ instead.

** New functions

*** ~org-publish-find-property~

This function can be used as a tool to format entries in a site-map,
in addition to ~org-publish-find-title~ and ~org-publish-find-date~.

*** ~org-list-to-org~

It is the reciprocal of ~org-list-to-lisp~, which see.

*** ~org-agenda-set-restriction-lock-from-agenda~

Call ~org-agenda-set-restriction-lock~ from the agenda.

** Miscellaneous

*** The Library of Babel now on Worg

The library-of-babel.org used to be accessible from the =doc/=
directory, distributed with Org’s core.  It is now accessible
from the Worg community-driven documentation [[https://orgmode.org/worg/library-of-babel.html][here]].

If you want to contribute to it, please see [[https://orgmode.org/worg/org-contribute.html][how to contribute]].

*** Allow multiple columns view

Columns view is not limited to a single buffer anymore.
*** Org Attach obeys ~dired-dwim-target~

When a Dired buffer is opened next to the Org document being edited,
the prompt for file to attach can start in the Dired buffer's
directory if `dired-dwim-target' in non-nil.

*** ~org-fill-paragraph~ can now fill a whole region
*** More specific anniversary descriptions

Anniversary descriptions (used in the agenda view, for instance)
include the point in time, when the anniversary appears.  This is,
in its most general form, just the date of the anniversary.  Or
more specific terms, like "today", "tomorrow" or "in n days" are
used to describe the time span.

This feature allows to automatically change the description of an
anniversary, depending on if it occurs in the next few days or
far away in the future.

*** Computed dates in tables appear as inactive time stamps

*** Save point before opening a file with an unknown search option

When following a file link with a search option (e.g., =::#custom-id=)
that doesn't exist in the target file, save position before raising an
error.  As a consequence, it is possible to jump back to the original
document with ~org-mark-ring-goto~ (default binding =C-c &=).

*** ~org-get-heading~ accepts two more optional arguments

See docstring for details.

*** New option ~org-babel-uppercase-example-markers~

This variable is a ~defcustom~ and replaces the variable
~org-babel-capitalize-example-region-markers~, which is a ~defvar~ and
is now obsolete.
*** =INCLUDE= keywords in commented trees are now ignored.
*** Default value for ~org-texinfo-text-markup-alist~ changed.

Now ~=...=~ markup uses ~@samp{}~ instead of ~@verb{}~.  You can use
~@verb{}~ again by customizing the variable.

*** Texinfo exports example blocks as ~@example~
*** Texinfo exports inline source blocks as ~@code{}~
*** Texinfo default table markup is ~@asis~

It used to be ~@samp~ but ~@asis~ is neutral and, therefore, more
suitable as a default value.

*** Texinfo default process includes ~--no-split~ option
*** New entities : ~\dollar~ and ~\USD~
*** Support for date style URLs in =org-protocol://open-source=

URLs like =https://cool-blog.com/2017/05/20/cool-post/= are covered by
rewrite rules.

*** Add (C) =COMMENT= support to ~org-structure-template-alist~

* Version 9.0

** Incompatible changes

*** Emacs 23 support has been dropped

From now on, Org expects at least Emacs 24.3, although Emacs 24.4 or
above is suggested.

*** XEmacs support has been dropped

Incomplete compatibility layer with XEmacs has been removed.  If you
want to take over maintenance of this compatibility, please contact
our mailing list.

*** New syntax for export blocks

Export blocks are explicitly marked as such at the syntax level to
disambiguate their parsing from special blocks.  The new syntax is

#+BEGIN_SRC org
,#+BEGIN_EXPORT backend
...
,#+END_EXPORT
#+END_SRC

instead of

#+BEGIN_SRC org
,#+BEGIN_backend
...
,#+END_backend
#+END_SRC

As a consequence, =INCLUDE= keywords syntax is modified, e.g.,

#+BEGIN_SRC org
,#+INCLUDE: "file.org" HTML
#+END_SRC

becomes

#+BEGIN_SRC org
,#+INCLUDE: "file.org" export html
#+END_SRC

The following function repairs export blocks and =INCLUDE= keywords
using previous syntax:

#+BEGIN_SRC emacs-lisp
(defun org-repair-export-blocks ()
  "Repair export blocks and INCLUDE keywords in current buffer."
  (interactive)
  (when (eq major-mode 'org-mode)
    (let ((case-fold-search t)
          (back-end-re (regexp-opt
                        '("HTML" "ASCII" "LATEX" "ODT" "MARKDOWN" "MD" "ORG"
                          "MAN" "BEAMER" "TEXINFO" "GROFF" "KOMA-LETTER")
                        t)))
      (org-with-wide-buffer
       (goto-char (point-min))
       (let ((block-re (concat "^[ \t]*#\\+BEGIN_" back-end-re)))
         (save-excursion
           (while (re-search-forward block-re nil t)
             (let ((element (save-match-data (org-element-at-point))))
               (when (eq (org-element-type element) 'special-block)
                 (save-excursion
                   (goto-char (org-element-property :end element))
                   (save-match-data (search-backward "_"))
                   (forward-char)
                   (insert "EXPORT")
                   (delete-region (point) (line-end-position)))
                 (replace-match "EXPORT \\1" nil nil nil 1))))))
       (let ((include-re
              (format "^[ \t]*#\\+INCLUDE: .*?%s[ \t]*$" back-end-re)))
         (while (re-search-forward include-re nil t)
           (let ((element (save-match-data (org-element-at-point))))
             (when (and (eq (org-element-type element) 'keyword)
                        (string= (org-element-property :key element) "INCLUDE"))
               (replace-match "EXPORT \\1" nil nil nil 1)))))))))
#+END_SRC

Moreover, ~:export-block~ keyword used in ~org-export-define-backend~ and
~org-export-define-derived-backend~ is no longer used and needs to be
removed.

*** Footnotes changes

**** [1]-like constructs are not valid footnotes

Using =[1]= as a footnote was already discouraged in the manual, since
it introduced too many false-positives in many Org documents.  These
constructs are now unsupported.

If you used =[N]= in some of your documents, consider turning them into
=[fn:N]=.

**** /Org Footnote/ library doesn't handle non-Org buffers

Commands for footnotes in an Org document no longer try to do
something in non-Org ones.  If you need to have footnotes there,
consider using the =footnote.el= library, shipped with Emacs.

In particular, ~org-footnote-tag-for-non-org-mode-files~ no longer
exists.

*** ~org-file-apps~ no longer accepts S-expressions as commands

The variable now accepts functions of two arguments instead of plain
S-expressions.  Replacing an S-expression with an appropriate function
is straightforward.  For example

: ("pdf" . (foo))

becomes

: ("pdf" . (lambda (file link) (foo)))

*** The ~{{{modification-time}}}~ macro can get time via =vc=

The modification time will be determined via =vc.el= if the second
argument is non-nil.  See the manual for details.

*** Preparation and completion functions in publishing projects change signature

Preparation and completion functions are now called with an argument,
which is the project property list.  It used to be dynamically scoped
through the ~project-plist~ variable.

*** Old Babel header properties are no longer supported

Using header arguments as property names is no longer possible.  As
such, the following

#+BEGIN_EXAMPLE
,* Headline
:PROPERTIES:
:exports: code
:var: a=1 b=2
:var+: c=3
:END:
#+END_EXAMPLE

should be written instead

#+BEGIN_EXAMPLE
,* Headline
:PROPERTIES:
:header-args: :exports code
:header-args+: :var a=1 b=2
:header-args+: :var c=3
:END:
#+END_EXAMPLE

Please note that, however, old properties were defined at the source
block definition.  Current ones are defined where the block is called.

** New features

*** ~org-eww~ has been moved into core
*** New org-protocol key=value syntax

Org-protocol can now handle query-style parameters such as:

#+begin_example
org-protocol://store-link?url=http:%2F%2Flocalhost%2Findex.html&title=The%20title
org-protocol://capture?template=x&title=Hello&body=World&url=http:%2F%2Fexample.com
#+end_example

Old-style links such as
: org-protocol://store-link:/http:%2F%2Flocalhost%2Findex.html/The%20title
continue to be supported.

If you have defined your own handler functions for
~org-protocol-protocol-alist~, change them to accept either a property
list (for new-style links) or a string (for old-style links).  Use
~org-protocol-parse-parameters~ to convert old-style links into property
lists.

*** New Org linter library

~org-lint~ can check syntax and report common issues in Org documents.

*** New option ~date-tree-last~ for ~org-agenda-insert-diary-strategy~

When ~org-agenda-insert-diary-strategy~ is set to ~date-tree-last~, diary
entries are added to last in the date tree.

*** New ~vbar~ entity

~\vbar~ or ~\vbar{}~ will be exported unconditionally as a =|=,
unlike to existing ~\vert~, which is expanded as ~&vert;~ when using
a HTML derived export back-end.

*** Export

**** New =#+latex_compiler= keyword to set LaTeX compiler.

PDFLaTeX, XeLaTeX, and LuaLaTeX are supported.  See the manual for
details.

**** New option ~org-export-with-broken-links~

This option tells the export process how to behave when encountering
a broken internal link.  See its docstring for more information.

**** Attributes support in custom language environments for LaTeX export

Custom language environments for LaTeX export can now define the
string to be inserted during export, using attributes to indicate the
position of the elements. See variable ~org-latex-custom-lang-environments~
for more details.

**** New Texinfo ~options~ attribute on special blocks

Using ~:options~ as a Texinfo attribute, it is possible to add
information to custom environments.  See manual for details.

**** New HTML ~id~ attributes on special, example and quote blocks

If the block has a =#+NAME:= attribute assigned, then the HTML element
will have an ~id~ attribute with that name in the HTML export. This
enables one to create links to these elements in other places, e.g.,
~<a href="#name">text</a>~.

**** Listings with captions are now numbered in HTML export

The class associated to the numbering is "listing-number".  If you
don't want these blocks to be numbered, as it was the case until now,
You may want to add ~.listing-number { display: none; }~ to the CSS
used.

**** Line Numbering in SRC/EXAMPLE blocks support arbitrary start number

The ~-n~ option to ~SRC~ and ~EXAMPLE~ blocks can now take a numeric
argument to specify the staring line number for the source or example
block.  The ~+n~ option can now take a numeric argument that will be
added to the last line number from the previous block as the starting
point for the SRC/EXAMPLE block.

#+BEGIN_SRC org
,#+BEGIN_SRC emacs-lisp -n 20
;; this will export with line number 20
(message "This is line 21")
,#+END_SRC
,#+BEGIN_SRC emacs-lisp +n 10
;; This will be listed as line 31
(message "This is line 32")
,#+END_SRC
#+END_SRC

**** Allow toggling center for images in LaTeX export

With the global variable ~org-latex-images-centered~ or the local
attribute ~:center~ it is now possible to center an image in LaTeX
export.

**** Default CSS class ~org-svg~ for SVG images in HTML export

SVG images exported in HTML are now by default assigned a CSS class
~org-svg~ if no CSS class is specified with the ~:class~ attribute. By
default, the CSS styling of class ~org-svg~ specifies an image width of
90\thinsp{}% of the container the image.

**** Markdown footnote export customization

Variables ~org-md-footnotes-section~ and ~org-md-footnote-format~
introduced for =ox-md.el=.  Both new variables define template strings
which can be used to customize the format of the exported footnotes
section and individual footnotes, respectively.

*** Babel

**** Blocks with coderefs labels can now be evaluated

The labels are removed prior to evaluating the block.

**** Support for Lua language
**** Support for SLY in Lisp blocks

See ~org-babel-lisp-eval-fn~ to activate it.

**** Support for Stan language

New ob-stan.el library.

Evaluating a Stan block can produce two different results.

1. Dump the source code contents to a file.

   This file can then be used as a variable in other blocks, which
   allows interfaces like RStan to use the model.

2. Compile the contents to a model file.

   This provides access to the CmdStan interface.  To use this, set
   ~org-babel-stan-cmdstan-directory~ and provide a ~:file~ argument
   that does not end in ".stan".

For more information and usage examples, visit
https://orgmode.org/worg/org-contrib/babel/languages/ob-doc-stan.html

**** Support for Oracle databases via ~sqlplus~

=ob-sql= library supports running SQL blocks against an Oracle
database using ~sqlplus~.  Use with properties like this (all
mandatory):

#+BEGIN_EXAMPLE
:engine oracle
:dbhost <host.com>
:dbport <1521>
:dbuser <username>
:database <database>
:dbpassword <secret>
#+END_EXAMPLE

**** Improved support to Microsoft SQL Server via ~sqlcmd~

=ob-sql= library removes support to the ~msosql~ engine which uses the
deprecated ~osql~ command line tool, and replaces it with ~mssql~
engine which uses the ~sqlcmd~ command line tool.  Use with properties
like this:

#+BEGIN_EXAMPLE
:engine mssql
:dbhost <host.com>
:dbuser <username>
:dbpassword <secret>
:database <database>
#+END_EXAMPLE

If you want to use the *trusted connection* feature, omit *both* the
=dbuser= and =dbpassword= properties and add =cmdline -E= to the properties.

If your Emacs is running in a Cygwin environment, the =ob-sql= library
can pass the converted path to the =sqlcmd= tool.

**** Improved support of header arguments for postgresql

The postgresql engine in a sql code block now supports ~:dbport~ and
~:dbpassword~ as header arguments.

**** Support for additional plantuml output formats

The support for output formats of [[https://plantuml.com/][plantuml]] has been extended to now
include:

All Diagrams:
- png ::
- svg ::
- eps ::
- pdf ::
- vdx ::
- txt :: ASCII art
- utxt :: ASCII art using unicode characters

Class Diagrams:
- xmi ::
- html ::

State Diagrams:
- scxml ::

The output formats are determined by the file extension specified
using the :file property, e.g.:

#+begin_src plantuml :file diagram.png
@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
@enduml
#+end_src

Please note that *pdf* *does not work out of the box* and needs additional
setup in addition to plantuml.  See [[https://plantuml.com/pdf.html]] for
details and setup information.

*** Rewrite of radio lists

Radio lists, i.e, Org plain lists in foreign buffers, have been
rewritten to be on par with Radio tables.  You can use a large set of
parameters to control how a given list should be rendered.  See manual
for details.

*** org-bbdb-anniversaries-future

Used like ~org-bbdb-anniversaries~, it provides a few days warning for
upcoming anniversaries (default: 7 days).

*** Clear non-repeated SCHEDULED upon repeating a task

If the task is repeated, and therefore done at least one, scheduling
information is no longer relevant.  It is therefore removed.

See [[git:481719fbd5751aaa9c672b762cb43aea8ee986b0][commit message]] for more information.

*** Support for ISO week trees

ISO week trees are an alternative date tree format that orders entries
by ISO week and not by month.

For example:

: * 2015
: ** 2015-W35
: ** 2015-W36
: *** 2015-08-31 Monday

They are supported in org-capture via ~file+weektree~ and
~file+weektree+prompt~ target specifications.

*** Accept ~:indent~ parameter when capturing column view

When defining a "columnview" dynamic block, it is now possible to add
an :indent parameter, much like the one in the clock table.

On the other hand, stars no longer appear in an ITEM field.

*** Columns view

**** ~org-columns~ accepts a prefix argument

When called with a prefix argument, ~org-columns~ apply to the whole
buffer unconditionally.

**** New variable : ~org-agenda-view-columns-initially~

The variable used to be a ~defvar~, it is now a ~defcustom~.

**** Allow custom summaries

It is now possible to add new summary types, or override those
provided by Org by customizing ~org-columns-summary-types~, which see.

**** Allow multiple summaries for any property

Columns can now summarize the same property using different summary
types.

*** Preview LaTeX snippets in buffers not visiting files
*** New option ~org-attach-commit~

When non-nil, commit attachments with git, assuming the document is in
a git repository.

*** Allow conditional case-fold searches in ~org-occur~

When set to ~smart~, the new variable ~org-occur-case-fold-search~ allows
to mimic =isearch.el=: if the regexp searched contains any upper case
character (or character class), the search is case sensitive.
Otherwise, it is case insensitive.

*** More robust repeated =ox-latex= footnote handling

Repeated footnotes are now numbered by referring to a label in the
first footnote.

*** The ~org-block~ face is inherited by ~src-blocks~

This works also when =org-src-fontify-natively= is non-nil.  It is also
possible to specify per-languages faces.  See =org-src-block-faces= and
the manual for details.

*** Links are now customizable

Links can now have custom colors, tooltips, keymaps, display behavior,
etc.  Links are now centralized in ~org-link-parameters~.

** New functions

*** ~org-next-line-empty-p~

It replaces the deprecated ~next~ argument to ~org-previous-line-empty-p~.

*** ~org-show-children~

It is a faster implementation of ~outline-show-children~.

** Removed functions

*** ~org-agenda-filter-by-tag-refine~ has been removed.

Use ~org-agenda-filter-by-tag~ instead.

*** ~org-agenda-todayp~ is deprecated.

Use ~org-agenda-today-p~ instead.

*** ~org-babel-get-header~ is removed.

Use ~org-babel--get-vars~ or ~assq~ instead, as applicable.

*** ~org-babel-trim~ is deprecated.

Use ~org-trim~ instead.

*** ~org-element-remove-indentation~ is deprecated.

Use ~org-remove-indentation~ instead.

*** ~org-image-file-name-regexp~ is deprecated

Use ~image-file-name-regexp~ instead.
The never-used-in-core ~extensions~ argument has been dropped.

*** ~org-list-parse-list~ is deprecated

Use ~org-list-to-lisp~ instead.

*** ~org-on-heading-p~ is deprecated

A comment to this effect was in the source code since 7.8.03, but
now a byte-compiler warning will be generated as well.

*** ~org-table-p~ is deprecated

Use ~org-at-table-p~ instead.

*** ~org-table-recognize-table.el~ is deprecated

It was not called by any org code since 2010.

*** Various reimplementations of cl-lib functions are deprecated

The affected functions are:
- ~org-count~
- ~org-remove-if~
- ~org-remove-if-not~
- ~org-reduce~
- ~org-every~
- ~org-some~

Additionally, ~org-sublist~ is deprecated in favor of ~cl-subseq~.  Note
the differences in indexing conventions: ~org-sublist~ is 1-based and
end-inclusive; ~cl-subseq~ is 0-based and end-exclusive.

** Removed options

*** Remove all options related to ~ido~ or ~iswitchb~

This includes ~org-completion-use-iswitchb~ and ~org-completion-use-ido~.
Instead Org uses regular functions, e.g., ~completion-read~ so as to
let those libraries operate.

*** Remove ~org-list-empty-line-terminates-plain-lists~

Two consecutive blank lines always terminate all levels of current
plain list.

*** ~fixltx2e~ is removed from ~org-latex-default-packages-alist~

fixltx2e is obsolete, see LaTeX News 22.

** Miscellaneous
*** Add Icelandic smart quotes
*** Allow multiple receiver locations in radio tables and lists
*** Allow angular links within link descriptions

It is now allowed to write, e.g.,
~[[http:orgmode.org][<file:unicorn.png>]]~ as an equivalent to
~[[http:orgmode.org][file:unicorn.png]]~.  The advantage of the former
is that spaces are allowed within the path.

*** Beamer export back-ends uses ~org-latex-prefer-user-labels~
*** ~:preparation-function~ called earlier during publishing

Functions in this list are called before any file is associated to the
current project.  Thus, they can be used to generate to be published
Org files.

*** Function ~org-remove-indentation~ changes.

The new algorithm doesn't remove TAB characters not used for
indentation.

*** Secure placeholders in capture templates

Placeholders in capture templates are no longer expanded recursively.
However, ~%(...)~ constructs are expanded very late, so you can fill
the contents of the S-exp with the replacement text of non-interactive
placeholders.  As before, interactive ones are still expanded as the
very last step, so the previous statement doesn't apply to them.

Note that only ~%(...)~ placeholders initially present in the
template, or introduced using a file placeholder, i.e., ~%[...]~ are
expanded.  This prevents evaluating potentially malicious code when
another placeholder, e.g., ~%i~ expands to a S-exp.

*** Links stored by ~org-gnus-store-link~ in nnir groups

Since gnus nnir groups are temporary, ~org-gnus-store-link~ now refers
to the article's original group.

*** ~org-babel-check-confirm-evaluate~ is now a function instead of a macro

The calling convention has changed.

*** HTML export table row customization changes

Variable ~org-html-table-row-tags~ has been split into
~org-html-table-row-open-tag~ and ~org-html-table-row-close-tag~.
Both new variables can be either a string or a function which will be
called with 6 parameters.

*** =ITEM= special property returns headline without stars
*** Rename ~org-insert-columns-dblock~ into ~org-columns-insert-dblock~

The previous name is, for the time being, kept as an obsolete alias.

*** ~org-trim~ can preserve leading indentation.

When setting a new optional argument to a non-nil value, ~org-trim~
preserves leading indentation while removing blank lines at the
beginning of the string.  The behavior is identical for white space at
the end of the string.

*** Function ~org-info-export~ changes.

HTML links created from certain info links now point to =gnu.org= URL's rather
than just to local files. For example info links such as =info:emacs#List
Buffers= used to be converted to HTML links like this:

: <a href="emacs.html#List-Buffers">emacs#List Buffers</a>

where local file =emacs.html= is referenced.
For most folks this file does not exist.
Thus the new behavior is to generate this HTML link instead:

: <a href="https://www.gnu.org/software/emacs/manual/html_mono/emacs.html#List-Buffers">emacs#List Buffers</a>

All emacs related info links are similarly translated plus few other
=gnu.org= manuals.

*** Repeaters with a ~++~ interval and a time can be shifted to later today

Previously, if a recurring task had a timestamp of
~<2016-01-01 Fri 20:00 ++1d>~ and was completed on =2016-01-02= at
=08:00=, the task would skip =2016-01-02= and would be rescheduled for
=2016-01-03=.  Timestamps with ~++~ cookies and a specific time will
now shift to the first possible future occurrence, even if the
occurrence is later the same day the task is completed.  (Timestamps
already in the future are still shifted one time further into the
future.)

*** ~org-mobile-action-alist~ is now a defconst

It used to be a defcustom, with a warning that it shouldn't be
modified anyway.

*** ~file+emacs~ and ~file+sys~ link types are deprecated

They are still supported in Org 9.0 but will eventually be removed in
a later release.  Use ~file~ link type along with universal arguments
to force opening it in either Emacs or with system application.

*** New defcustom ~org-babel-J-command~ stores the j command
*** New defalias ~org-babel-execute:j~

Allows J source blocks be indicated by letter j.  Previously the
indication letter was solely J.

*** ~org-open-line~ ignores tables at the very beginning of the buffer

When ~org-special-ctrl-o~ is non-nil, it is impractical to create
a blank line above a table at the beginning of the document. Now, as
a special case, ~org-open-line~ behaves normally in this situation.

*** ~org-babel-hash-show-time~ is now customizable

The experimental variable used to be more or less confidential, as
a ~defvar~.

*** New ~:format~ property to parsed links

It defines the format of the original link.  Possible values are:
~plain~, ~bracket~ and ~angle~.

* Version 8.3

** Incompatible changes

*** Properties drawers syntax changes

Properties drawers are now required to be located right after a
headline and its planning line, when applicable.

It will break some documents as TODO states changes were sometimes
logged before the property drawer.

The following function will repair them:

#+BEGIN_SRC emacs-lisp
(defun org-repair-property-drawers ()
  "Fix properties drawers in current buffer.
Ignore non Org buffers."
  (when (eq major-mode 'org-mode)
    (org-with-wide-buffer
     (goto-char (point-min))
     (let ((case-fold-search t)
           (inline-re (and (featurep 'org-inlinetask)
                           (concat (org-inlinetask-outline-regexp)
                                   "END[ \t]*$"))))
       (org-map-entries
        (lambda ()
          (unless (and inline-re (org-looking-at-p inline-re))
            (save-excursion
              (let ((end (save-excursion (outline-next-heading) (point))))
                (forward-line)
                (when (org-looking-at-p org-planning-line-re) (forward-line))
                (when (and (< (point) end)
                           (not (org-looking-at-p org-property-drawer-re))
                           (save-excursion
                             (and (re-search-forward org-property-drawer-re end t)
                                  (eq (org-element-type
                                       (save-match-data (org-element-at-point)))
                                      'drawer))))
                  (insert (delete-and-extract-region
                           (match-beginning 0)
                           (min (1+ (match-end 0)) end)))
                  (unless (bolp) (insert "\n"))))))))))))
#+END_SRC

*** Using "COMMENT" is now equivalent to commenting with "#"

If you used "COMMENT" in headlines to prevent a subtree from being
exported, you can still do it but all information within the subtree
is now commented out, i.e. no #+OPTIONS line will be parsed or taken
into account when exporting.

If you want to exclude a headline from export while using its contents
for setting options, use =:noexport:= (see =org-export-exclude-tags=.)

*** =#+CATEGORY= keywords no longer apply partially to document

It was possible to use several such keywords and have them apply to
the text below until the next one, but strongly deprecated since Org
5.14 (2008).

=#+CATEGORY= keywords are now global to the document.  You can use node
properties to set category for a subtree, e.g.,

#+BEGIN_SRC org
,* Headline
   :PROPERTIES:
   :CATEGORY: some category
   :END:
#+END_SRC

*** New variable to control visibility when revealing a location

~org-show-following-heading~, ~org-show-siblings~, ~org-show-entry-below~
and ~org-show-hierarchy-above~ no longer exist.  Instead, visibility is
controlled through a single variable: ~org-show-context-detail~, which
see.

*** Replace disputed keys again when reading a date

~org-replace-disputed-keys~ has been ignored when reading date since
version 8.1, but the former behavior is restored again.

Keybinding for reading date can be customized with a new variable
~org-read-date-minibuffer-local-map~.

*** No default title is provided when =TITLE= keyword is missing

Skipping =TITLE= keyword no longer provides the current file name, or
buffer name, as the title.  Instead, simply ignore the title.

*** Default bindings of =C-c C-n= and =C-c C-p= changed

The key sequences =C-c C-n= and =C-c C-p= are now bound to
~org-next-visible-heading~ and ~org-previous-visible-heading~
respectively, rather than the =outline-mode= versions of these
functions.  The Org version of these functions skips over inline tasks
(and even-level headlines when ~org-odd-levels-only~ is set).

*** ~org-element-context~ no longer return objects in keywords

~org-element-context~ used to return objects on some keywords, i.e.,
=TITLE=, =DATE= and =AUTHOR=.  It now returns only the keyword.

*** ~org-timer-default-timer~ type changed from number to string

If you have, in your configuration, something like =(setq
org-timer-default-timer 10)= replace it with =(setq
org-timer-default-timer "10")=.

*** Functions signature changes

The following functions require an additional argument.  See their
docstring for more information.

- ~org-export-collect-footnote-definitions~
- ~org-html-format-headline-function~
- ~org-html-format-inlinetask-function~
- ~org-latex-format-headline-function~
- ~org-latex-format-inlinetask-function~
- ~org-link-search~

** New features

*** Default lexical evaluation of emacs-lisp source blocks

Emacs-lisp source blocks in Babel are now evaluated using lexical
scoping.  There is a new header to control this behavior.

The default results in an eval with lexical scoping.
:lexical yes

This turns lexical scoping off in the eval (the former behavior).
:lexical no

This uses the lexical environment with x=42 in the eval.
:lexical '((x . 42))

*** Behavior of ~org-return~ changed

If point is before or after the headline title, insert a new line
without changing the headline.

*** Hierarchies of tags

The functionality of nesting tags in hierarchies is added to Org mode.
This is the generalization of what was previously called "Tag groups"
in the manual.  That term is now changed to "Tag hierarchy".

The following in-buffer definition:

#+BEGIN_SRC org
  ,#+TAGS: [ Group : SubOne SubTwo ]
  ,#+TAGS: [ SubOne : SubOne1 SubOne2 ]
  ,#+TAGS: [ SubTwo : SubTwo1 SubTwo2 ]
#+END_SRC

Should be seen as the following tree of tags:

- Group
  - SubOne
    - SubOne1
    - SubOne2
  - SubTwo
    - SubTwo1
    - SubTwo2

Searching for "Group" should return all tags defined above.  Filtering
on SubOne filters also it's sub-tags.  Etc.

There is no limit on the depth for the tag hierarchy.

*** Additional syntax for non-unique grouptags

Additional syntax is defined for grouptags if the tags in the group
don't have to be distinct on a heading.

Grouptags had to previously be defined with { }.  This syntax is
already used for exclusive tags and Grouptags need their own,
non-exclusive syntax.  This behavior is achieved with [ ].  Note: { }
can still be used also for Grouptags but then only one of the given
tags can be used on the headline at the same time.  Example:

[ group : sub1 sub2 ]

#+BEGIN_SRC org
,* Test                                                            :sub1:sub2:
#+END_SRC

This is a more general case than the already existing syntax for
grouptags; { }.

*** Define regular expression patterns as tags

Tags can be defined as grouptags with regular expressions as
"sub-tags".

The regular expressions in the group must be marked up within { }.
Example use:

: #+TAGS: [ Project : {P@.+} ]

Searching for the tag Project will now list all tags also including
regular expression matches for P@.+.  This is good for example for
projects tagged with a common identifier, i.e. P@2014_OrgTags.

*** Filtering in the agenda on grouptags (Tag hierarchies)

Filtering in the agenda on grouptags filters all of the related tags.
Except if a filter is applied with a (double) prefix-argument.

Filtering in the agenda on subcategories does not filter the "above"
levels anymore.

If a grouptag contains a regular expression the regular expression
is also used as a filter.

*** Minor refactoring of ~org-agenda-filter-by-tag~

Now uses the argument ARG and optional argument exclude instead of
strip and narrow.  ARG because the argument has multiple purposes and
makes more sense than strip now.  The term "narrowing" is changed to
exclude.

The main purpose is for the function to make more logical sense when
filtering on tags now when tags can be structured in hierarchies.

*** Babel: support for sed scripts

Thanks to Bjarte Johansen for this feature.

*** Babel: support for Processing language

New ob-processing.el library.

This library implements necessary functions for implementing editing
of Processing code blocks, viewing the resulting sketches in an
external viewer, and HTML export of the sketches.

Check the documentation for more details.

Thanks to Jarmo Hurri for this feature.

*** New behavior for ~org-toggle-latex-fragment~

The new behavior is the following:

- With a double prefix argument or with a single prefix argument when
  point is before the first headline, toggle overlays in the whole
  buffer;

- With a single prefix argument, toggle overlays in the current
  subtree;

- On latex code, toggle overlay at point;

- Otherwise, toggle overlays in the current section.

*** Additional markup with =#+INCLUDE= keyword

The content of the included file can now be optionally marked up, for
instance as HTML.  See the documentation for details.

*** File links with =#+INCLUDE= keyword

Objects can be extracted via =#+INCLUDE= using file links.  It is
possible to include only the contents of the object.  See manual for
more information.

*** Drawers do not need anymore to be referenced in =#+DRAWERS=

One can use a drawer without listing it in the =#+DRAWERS= keyword,
which is now obsolete.  As a consequence, this change also deprecates
~org-drawers~ variable.

*** ~org-edit-special~ can edit export blocks

Using C-c ' on an export block now opens a sub-editing buffer.  Major
mode in that buffer is determined by export backend name (e.g.,
"latex" \to "latex-mode").  You can define exceptions to this rule by
configuring ~org-src-lang-modes~, which see.

*** Additional =:hline= processing to ob-shell

If the argument =:hlines yes= is present in a babel call, an optional
argument =:hlines-string= can be used to define a string to use as a
representation for the lisp symbol ='hline= in the shell program.  The
default is =hline=.

*** Markdown export supports switches in source blocks

For example, it is now possible to number lines using the =-n= switch in
a source block.

*** New option in ASCII export

Plain lists can have an extra margin by setting ~org-ascii-list-margin~
variable to an appropriate integer.

*** New blocks in ASCII export

ASCII export now supports =#+BEGIN_JUSTIFYRIGHT= and =#+BEGIN_JUSTIFYLEFT=
blocks.  See documentation for details.

*** More back-end specific publishing options

The number of publishing options specific to each back-end has been
increased.  See manual for details.

*** Export inline source blocks

Inline source code was used to be removed upon exporting.  They are
now handled as standard code blocks, i.e., the source code can appear
in the output, depending on the parameters.

*** Extend ~org-export-first-sibling-p~ and ~org-export-last-sibling-p~

These functions now support any element or object, not only headlines.

*** New function: ~org-export-table-row-in-header-p~

*** New function: ~org-export-get-reference~

*** New function: ~org-element-lineage~

This function deprecates ~org-export-get-genealogy~.  It also provides
more features.  See docstring for details.

*** New function: ~org-element-copy~

*** New filter: ~org-export-filter-body-functions~

Functions in this filter are applied on the body of the exported
document, before wrapping it within the template.

*** New :environment parameter when exporting example blocks to LaTeX

: #+ATTR_LATEX: :environment myverbatim
: #+BEGIN_EXAMPLE
: This sentence is false.
: #+END_EXAMPLE

will be exported using =@samp(myverbatim)= instead of =@samp(verbatim)=.

*** Various improvements on radio tables

Radio tables feature now relies on Org's export framework ("ox.el").
~:no-escape~ parameter no longer exists, but additional global
parameters are now supported: ~:raw~, ~:backend~.  Moreover, there are new
parameters specific to some pre-defined translators, e.g.,
~:environment~ and ~:booktabs~ for ~orgtbl-to-latex~.  See translators
docstrings (including ~orgtbl-to-generic~) for details.

*** Non-floating minted listings in Latex export

It is not possible to specify =#+attr_latex: :float nil= in conjunction
with source blocks exported by the minted package.

*** Field formulas can now create columns as needed

Previously, evaluating formulas that referenced out-of-bounds columns
would throw an error. A new variable ~org-table-formula-create-columns~
was added to adjust this behavior. It is now possible to silently add
new columns, to do so with a warning or to explicitly ask the user
each time.

*** ASCII plot

Ability to plot values in a column through ASCII-art bars.  See manual
for details.

*** New hook: ~org-archive-hook~

This hook is called after successfully archiving a subtree, with point
on the original subtree, not yet deleted.

*** New option: ~org-attach-archive-delete~

When non-nil, attachments from archived subtrees are removed.

*** New option: ~org-latex-caption-above~

This variable generalizes ~org-latex-table-caption-above~, which is now
deprecated.  In addition to tables, it applies to source blocks,
special blocks and images.  See docstring for more information.

*** New option: ~org-latex-prefer-user-labels~

See the docstring for more information.

*** Export unnumbered headlines

Headlines, for which the property ~UNNUMBERED~ is non-nil, are now
exported without section numbers irrespective of their levels.  The
property is inherited by children.

*** Tables can be sorted with an arbitrary function

It is now possible to specify a function, both programmatically,
through a new optional argument, and interactively with ~f~ or ~F~ keys,
to sort a table.

*** Table of contents can be local to a section

The ~TOC~ keywords now accepts an optional ~local~ parameter.  See manual
for details.

*** Countdown timers can now be paused

~org-timer-pause-time~ now pauses and restarts both relative and
countdown timers.

*** New option ~only-window~ for ~org-agenda-window-setup~

When ~org-agenda-window-setup~ is set to ~only-window~, the agenda is
displayed as the sole window of the current frame.

*** ~{{{date}}}~ macro supports optional formatting argument

It is now possible to supply and optional formatting argument to
~{{{date}}}~. See manual for details.

*** ~{{{property}}}~ macro supports optional search argument

It is now possible to supply an optional search option to
~{{{property}}}~ in order to retrieve remote properties optional.  See
manual for details.

*** New option ~org-export-with-title~

It is possible to suppress the title insertion with ~#+OPTIONS:
title:nil~ or globally using the variable ~org-export-with-title~.

*** New entities family: "\_ "

"\_ " are used to insert up to 20 contiguous spaces in various
back-ends.  In particular, this family can be used to introduce
leading spaces within table cells.

*** New MathJax configuration options

Org uses the MathJax CDN by default.  See the manual and the docstring
of ~org-html-mathjax-options~ for details.

*** New behavior in `org-export-options-alist'

When defining a back-end, it is now possible to specify to give
`parse' behavior on a keyword.  It is equivalent to call
`org-element-parse-secondary-string' on the value.

However, parsed =KEYWORD= is automatically associated to an
=:EXPORT_KEYWORD:= property, which can be used to override the keyword
value during a subtree export.  Moreover, macros are expanded in such
keywords and properties.

*** Viewport support in html export

Viewport for mobile-optimized website is now automatically inserted
when exporting to html.  See ~org-html-viewport~ for details.

*** New ~#+SUBTITLE~ export keyword

Org can typeset a subtitle in some export backends.  See the manual
for details.

*** Remotely edit a footnote definition

Calling ~org-edit-footnote-reference~ (C-c ') on a footnote reference
allows to edit its definition, as long as it is not anonymous, in a
dedicated buffer.  It works even if buffer is currently narrowed.

*** New function ~org-delete-indentation~ bound to ~M-^~

Work as ~delete-indentation~ unless at heading, in which case text is
added to headline text.

*** Support for images in Texinfo export

~Texinfo~ back-end now handles images.  See the manual for details.

*** Support for captions in Texinfo export

Tables and source blocks can now have captions.  Additionally, lists
of tables and lists of listings can be inserted in the document with
=#+TOC= keyword.

*** Countdown timer support hh:mm:ss format

In addition to setting countdown timers in minutes, they can also be
set using the hh:mm:ss format.

*** Extend ~org-clone-subtree-with-time-shift~

~org-clone-subtree-with-time-shift~ now accepts 0 as an argument for the
number of clones, which removes the repeater from the original subtree
and creates one shifted, repeating clone.

*** New time block for clock tables: ~untilnow~

It encompasses all past closed clocks.

*** Support for the ~polyglossia~ LaTeX package

See the docstring of ~org-latex-classes~ and
~org-latex-guess-polyglossia-language~ for details.

*** None-floating tables, graphics and blocks can have captions

*** `org-insert-heading' can be forced to insert top-level headline

** Removed functions

*** Removed function ~org-translate-time~

Use ~org-timestamp-translate~ instead.

*** Removed function ~org-beamer-insert-options-template~

This function inserted a Beamer specific template at point or in
current subtree.  Use ~org-export-insert-default-template~ instead, as
it provides more features and covers all export back-ends.  It is also
accessible from the export dispatcher.

*** Removed function ~org-timer-cancel-timer~

~org-timer-stop~ now stops both relative and countdown timers.

*** Removed function ~org-export-solidify-link-text~

This function, being non-bijective, introduced bug in internal
references.  Use ~org-export-get-reference~ instead.

*** Removed function ~org-end-of-meta-data-and-drawers~

The function is superseded by ~org-end-of-meta-data~, called with an
optional argument.

*** Removed functions ~org-table-colgroup-line-p~, ~org-table-cookie-line-p~

These functions were left-over from pre 8.0 era.  They are not correct
anymore.  Since they are not needed, they have no replacement.

** Removed options

*** ~org-list-empty-line-terminates-plain-lists~ is deprecated

It will be kept in code base until next release, for backward
compatibility.

If you need to separate consecutive lists with blank lines, always use
two of them, as if this option was nil (default value).

*** ~org-export-with-creator~ is a boolean

Special ~comment~ value is no longer allowed.  It is possible to use a
body filter to add comments about the creator at the end of the
document instead.

*** Removed option =org-html-use-unicode-chars=

Setting this to non-nil was problematic as it converted characters
everywhere in the buffer, possibly corrupting URLs.

*** Removed option =org-babel-sh-command=

This undocumented option defaulted to the value of =shell-file-name= at
the time of loading =ob-shell=.  The new behavior is to use the value
of =shell-file-name= directly when the shell language is =shell=.  To chose
a different shell, either customize =shell-file-name= or bind this
variable locally.

*** Removed option =org-babel-sh-var-quote-fmt=

This undocumented option was supposed to provide different quoting
styles when changing the shell type.  Changing the shell type can now
be done directly from the source block and the quoting style has to be
compatible across all shells, so a customization doesn't make sense
anymore.  The chosen hard coded quoting style conforms to POSIX.

*** Removed option ~org-insert-labeled-timestamps-at-point~

Setting this option to anything else that the default value (nil)
would create invalid planning info.  This dangerous option is now
removed.

*** Removed option ~org-koma-letter-use-title~

Use org-export-with-title instead.  See also below.

*** Removed option ~org-entities-ascii-explanatory~

This variable has no effect since Org 8.0.

*** Removed option ~org-table-error-on-row-ref-crossing-hline~

This variable has no effect since August 2009.

*** Removed MathML-related options from ~org-html-mathjax-options~

MathJax automatically chooses the best display technology based on the
end-users browser.  You may force initial usage of MathML via
~org-html-mathjax-template~ or by setting the ~path~ property of
~org-html-mathjax-options~.

*** Removed comment-related filters

~org-export-filter-comment-functions~ and
~org-export-filter-comment-block-functions~ variables do not exist
anymore.

** Miscellaneous

*** Strip all meta data from ITEM special property

ITEM special property does not contain TODO, priority or tags anymore.

*** File names in links accept are now compatible with URI syntax

Absolute file names can now start with =///= in addition to =/=. E.g.,
=[[file:///home/me/unicorn.jpg]]=.

*** Footnotes in included files are now local to the file

As a consequence, it is possible to include multiple Org files with
footnotes in a master document without being concerned about footnote
labels colliding.

*** Mailto links now use regular URI syntax

This change deprecates old Org syntax for mailto links:
=mailto:user@domain::Subject=.

*** =QUOTE= keywords do not exist anymore

=QUOTE= keywords have been deprecated since Org 8.2.

*** Select tests to perform with the build system

The build system has been enhanced to allow test selection with a
regular expression by defining =BTEST_RE= during the test invocation.
This is especially useful during bisection to find just when a
particular test failure was introduced.

*** Exact heading search for external links ignore spaces and cookies

Exact heading search for links now ignore spaces and cookies. This is
the case for links of the form ~file:projects.org::*task title~, as well
as links of the form ~file:projects.org::some words~ when
~org-link-search-must-match-exact-headline~ is not nil.

*** ~org-latex-hyperref-template~, ~org-latex-title-command~ formatting

New formatting keys are supported.  See the respective docstrings.
Note, ~org-latex-hyperref-template~ has a new default value.

*** ~float, wasysym, marvosym~ are removed from ~org-latex-default-packages-alist~

If you require any of these package add them to your preamble via
~org-latex-packages-alist~. Org also uses default LaTeX ~\tolerance~ now.

*** When exporting, throw an error on unresolved id/fuzzy links and code refs

This helps spotting wrong links.

* Version 8.2

** Incompatible changes
*** =ob-sh.el= renamed to =ob-shell=
This may require two changes in user config.

1. In =org-babel-do-load-languages=, change =(sh . t)= to =(shell . t)=.
2. Edit =local.mk= files to change the value of =BTEST_OB_LANGUAGES=
   to remove "sh" and include "shell".

*** Combine org-mac-message.el and org-mac-link-grabber into org-mac-link.el

Please remove calls to =(require 'org-mac-message)= and =(require
'org-mac-link-grabber)= in your =.emacs= initialization file.  All you
need now is =(require 'org-mac-link)=.

Additionally, replace any calls to =ogml-grab-link= to
=org-mac-grab-link=.  For example, replace this line:

: (define-key org-mode-map (kbd "C-c g") 'omgl-grab-link)

with this:

: (define-key org-mode-map (kbd "C-c g") 'org-mac-grab-link)

*** HTML export: Replace =HTML_HTML5_FANCY= by =:html-html5-fancy= (...)

Some of the HTML specific export options in Org <8.1 are either nil or
t, like =#+HTML_INCLUDE_STYLE=.  We replaced these binary options with
option keywords like :html-include-style.

So you need to replace

: #+HTML_INCLUDE_STYLE: t

by

: #+OPTIONS: :html-include-style t

Options affected by this change: =HTML5_FANCY=, =HTML_INCLUDE_SCRIPTS=
and =HTML_INCLUDE_STYLE=.

*** Add an argument to ~org-export-to-file~ and ~org-export-to-buffer~

~org-export-to-file~ and ~org-export-to-file~ can run in a different
process when provided a non-nil =ASYNC= optional argument, without
relying on ~org-export-async-start~ macro.

Since =ASYNC= is the first of optional arguments, you have to shift
the other optional arguments accordingly.

*** Export back-ends are now structures

Export back-ends are now structures, and stored as such in the
communication channel during an export process.  In other words, from
now on, ~(plist-get info :back-end)~ will return a structure instead
of a symbol.

Arguments in hooks and in filters are still symbols, though.

** Important bugfixes

*** [[doc:org-insert-heading][org-insert-heading]] has been rewritten and bugs are now fixed
*** The replacement of disputed keys is now turned of when reading a date

*** Match string for sparse trees can now contain a slash in a property value

    You can now have searches like SOMEPROP="aaa/bbb".  Until now,
    this would break because the slash would be interpreted as the
    separator starting a TOTO match string.
** New features

*** =C-c ^ x= will now sort checklist items by their checked status

See [[doc:org-sort-list][org-sort-list]]: hitting =C-c ^ x= will put checked items at the end
of the list.
*** Various LaTeX export enhancements

- Support SVG images
- Support for .pgf files
- LaTeX Babel blocks can now be exported as =.tikz= files
- Allow =latexmk= as an option for [[doc:org-latex-pdf-process][org-latex-pdf-process]]
- When using =\usepackage[AUTO]{babel}=, AUTO will automatically be
  replaced with a value compatible with ~org-export-default-language~
  or ~LANGUAGE~ keyword.
- The dependency on the =latexsym= LaTeX package has been removed, we
  now use =amssymb= symbols by default instead.

*** New functions for paragraph motion

    The commands =C-down= and =C-up= now invoke special commands
    that use knowledge from the org-elements parser to move the cursor
    in a paragraph-like way.

*** New entities in =org-entities.el=

Add support for ell, imath, jmath, varphi, varpi, aleph, gimel, beth,
dalet, cdots, S (§), dag, ddag, colon, therefore, because, triangleq,
leq, geq, lessgtr, lesseqgtr, ll, lll, gg, ggg, prec, preceq,
preccurlyeq, succ, succeq, succurlyeq, setminus, nexist(s), mho,
check, frown, diamond.  Changes loz, vert, checkmark, smile and tilde.

*** Anonymous export back-ends

~org-export-create-backend~ can create anonymous export back-ends,
which can then be passed to export functions like
~org-export-to-file~, ~org-export-to-buffer~ or ~org-export-as~.

It allows for quick translation of Org syntax without the overhead of
registering a new back-end.

*** New agenda fortnight view

    The agenda has not, in addition to day, week, month, and year
    views, also a fortnight view covering 14 days.
** New options

*** New option [[doc:org-bookmark-names-plist][org-bookmark-names-plist]]

This allows to specify the names of automatic bookmarks.
*** New option [[doc:org-agenda-ignore-drawer-properties][org-agenda-ignore-drawer-properties]]

This allows more flexibility when optimizing the agenda generation.
See https://orgmode.org/worg/agenda-optimization.html for details.
*** New option: [[doc:org-html-link-use-abs-url][org-html-link-use-abs-url]] to force using absolute URLs

This is an export/publishing option, and should be used either within
the =#+OPTIONS= line(s) or within a [[doc:org-publish-project-alist][org-publish-project-alist]].

Setting this option to =t= is needed when the HTML output does not
allow relative URLs.  For example, the =contrib/lisp/ox-rss.el=
library produces a RSS feed, and RSS feeds need to use absolute URLs,
so a combination of =:html-link-home "..." and :html-link-use-abs-url
t= is required---see the configuration example in the comment section
of =ox-rss.el=.

*** New option [[doc:org-babel-ditaa-java-cmd][org-babel-ditaa-java-cmd]]

This makes java executable configurable for ditaa blocks.

*** New options [[doc:org-babel-latex-htlatex][org-babel-latex-htlatex]] and [[doc:org-babel-latex-htlatex-packages][org-babel-latex-htlatex-packages]]

This enables SVG generation from latex code blocks.

*** New option: [[doc:org-habit-show-done-always-green][org-habit-show-done-always-green]]

See [[https://lists.gnu.org/r/emacs-orgmode/2013-05/msg00214.html][this message]] from Max Mikhanosha.

*** New option: [[doc:org-babel-inline-result-wrap][org-babel-inline-result-wrap]]

If you set this to the following

: (setq org-babel-inline-result-wrap "$%s$")

then inline code snippets will be wrapped into the formatting string.

*** New option: [[doc:org-special-ctrl-o][org-special-ctrl-o]]

    This variable can be used to turn off the special behavior of
    =C-o= in tables.
** New contributed packages

- =ox-bibtex.el= by Nicolas Goaziou :: an utility to handle BibTeX
     export to both LaTeX and HTML exports.  It uses the [[https://www.lri.fr/~filliatr/bibtex2html/][bibtex2html]]
     software.

- =org-screenshot.el= by Max Mikhanosha :: an utility to handle
     screenshots easily from Org, using the external tool [[https://freecode.com/projects/scrot][scrot]].

** Miscellaneous

*** "QUOTE" keywords in headlines are deprecated

"QUOTE" keywords are an undocumented feature in Org.  When a headline
starts with the keyword "QUOTE", its contents are parsed as
a ~quote-section~ and treated as an example block.  You can achieve
the same with example blocks.

This feature is deprecated and will be removed in the next Org
release.

* Version 8.0.1

** Installation

Installation instructions have been updated and simplified.

If you have troubles installing or updating Org, focus on these
instructions:

- when updating via a =.zip/.tar.gz= file, you only need to set the
  =load-path= in your =.emacs=.  Set it before any other Org
  customization that would call autoloaded Org functions.

- when updating by pulling Org's Git repository, make sure to create the
  correct autoloads.  You can do this by running =~$ make autoloads= (to
  only create the autoloads) or by running =~$ make= (to also compile
  the Emacs lisp files.)  =~$ make help= and =~$ make helpall= gives you
  detailed explanations.

- when updating through ELPA (either from GNU ELPA or from Org ELPA),
  you have to install Org's ELPA package in a session where no Org
  function has been called already.

When in doubt, run =M-x org-version RET= and see if you have a mixed-up
installation.

See https://orgmode.org/org.html#Installation for details.

** Incompatible changes

Org 8.0 is the most disruptive major version of Org.

If you configured export options, you will have to update some of them.

If you used =#+ATTR_*= keywords, the syntax of the attributes changed and
you will have to update them.

Below is a list of changes for which you need to take action.

See https://orgmode.org/worg/org-8.0.html for the most recent version of
this list and for detailed instructions on how to migrate.

**** New export engine

Org 8.0 comes with a new export engine written by Nicolas Goaziou.  This
export engine relies on ~org-element.el~ (Org's syntax parser), which was
already in Org's core.  This new export engine triggered the rewriting of
/all/ export back-ends.

The most visible change is the export dispatcher, accessible through the
keybinding =C-c C-e=.  By default, this menu only shows some of the
built-in export formats, but you can add more formats by loading them
directly (e.g., =(require 'ox-texinfo)= or by configuring the option
[[doc:org-export-backends][org-export-backends]].

More contributed back-ends are available from the =contrib/= directory, the
corresponding files start with the =ox-= prefix.

If you customized an export back-end (like HTML or LaTeX), you will need to
rename some options so that your customization is not lost.  Typically, an
option starting with =org-export-html-= is now named =org-html-=.  See the
manual for details and check [[https://orgmode.org/worg/org-8.0.html][this Worg page]] for directions.

**** New syntax for #+ATTR_HTML/LaTeX/... options

     : #+ATTR_HTML width="200px"

     should now be written

     : #+ATTR_HTML :width 200px

     Keywords like =#+ATTR_HTML= and =#+ATTR_LaTeX= are defined in their
     respective back-ends, and the list of supported parameters depends on
     each backend.  See Org's manual for details.

**** ~org-remember.el~ has been removed

     You cannot use =remember.el= anymore to capture notes.

     Support for remember templates has been obsoleted since long, it is
     now fully removed.

     Use =M-x org-capture-import-remember-templates RET= to import your
     remember templates into capture templates.

**** ~org-jsinfo.el~ has been merged into ~ox-html.el~

     If you were requiring ~ox-jsinfo.el~ in your ~.emacs.el~ file, you
     will have to remove this requirement from your initialization file.

**** Note for third-party developers

     The name of the files for export back-end have changed: we now use the
     prefix =ox-= for those files (like we use the =ob-= prefix for Babel
     files.)  For example ~org-html.el~ is now ~ox-html.el~.

     If your code relies on these files, please update the names in your
     code.

**** Packages moved from core to contrib

     Since packages in Org's core are meant to be part of GNU Emacs, we try
     to be minimalist when it comes to adding files into core.  For 8.0, we
     moved some contributions into the =contrib/= directory.

     The rationale for deciding that these files should live in =contrib/=
     is either because they rely on third-party software that is not
     included in Emacs, or because they are not targeting a significant
     user-base.

     - org-colview-xemacs.el
     - org-mac-message.el
     - org-mew.el
     - org-wl.el
     - ox-freedmind.el
     - ox-taskjuggler.el

     Note that ~ox-freedmind.el~ has been rewritten by Jambunathan,
     ~org-mew.el~ has been enhanced by Tokuya Kameshima and
     ~ox-taskjuggler.el~ by Nicolas Goaziou and others.

     Also, the Taskjuggler exporter now uses TJ3 by default.  John Hendy
     wrote [[https://orgmode.org/worg/org-tutorials/org-taskjuggler3.html][a tutorial on Worg]] for the TJ3 export.

** New packages in core

*** ~ob-makefile.el~ by Eric Schulte and Thomas S. Dye

    =ob-makefile.el= implements Org Babel support for Makefile tangling.

*** ~ox-man.el~ by Luis Anaya

    =ox-man.el= allows you to export Org files to =man= pages.

*** ~ox-md.el~ by Nicolas Goaziou

    =ox-md.el= allows you to export Org files to Markdown files, using the
    vanilla [[https://daringfireball.net/projects/markdown/][Markdown syntax]].

*** ~ox-texinfo.el~ by Jonathan Leech-Pepin

    =ox-texinfo.el= allows you to export Org files to [[https://www.gnu.org/software/texinfo/][Texinfo]] files.

** New packages in contrib

*** ~ob-julia.el~ by G. Jay Kerns

    [[https://julialang.org/][Julia]] is a new programming language.

    =ob-julia.el= provides Org Babel support for evaluating Julia source
    code.

*** ~ob-mathomatic.el~ by Luis Anaya

    [[https://www.mathomatic.org/][mathomatic]] a portable, command-line, educational CAS and calculator
    software, written entirely in the C programming language.

    ~ob-mathomatic.el~ provides Org Babel support for evaluating mathomatic
    entries.

*** ~ob-tcl.el~ by Luis Anaya

    ~ob-tcl.el~ provides Org Babel support for evaluating [[https://www.tcl.tk/][Tcl]] source code.

*** ~org-bullets.el~ by Evgeni Sabof

    Display bullets instead of stars for headlines.

    Also see [[https://orgmode.org/worg/org-faq.html#sec-8-12][this updated FAQ]] on how to display another character than "*"
    for starting headlines.

*** ~org-favtable.el~ by Marc-Oliver Ihm

    ~org-favtable.el~ helps you to create and update a table of favorite
    locations in org, keeping the most frequently visited lines right at
    the top.  This table is called "favtable".  See the documentation on
    [[https://orgmode.org/worg/org-contrib/org-favtable.html][Worg]].

*** ~ox-confluence.el~ by Sébastien Delafond

    ~ox-confluence.el~ lets you convert Org files to [[https://confluence.atlassian.com/display/DOC/Confluence%2BWiki%2BMarkup][Confluence Wiki]] files.

*** ~ox-deck.el~ and ~ox-s5.el~ by Rick Frankel

    [[http://imakewebthings.com/deck.js/][deck.js]] is a javascript library for displaying HTML ages as
    presentations.  ~ox-deck.el~ exports Org files to HTML presentations
    using =deck.js=.

    [[https://meyerweb.com/eric/tools/s5/][s5]] is a set of scripts which also allows to display HTML pages as
    presentations.  ~ox-s5.el~ exports Org files to HTML presentations
    using =s5=.

*** ~ox-groff.el~ by Luis Anaya and Nicolas Goaziou

    The [[https://www.gnu.org/software/groff/][groff]] (GNU troff) software is a typesetting package which reads
    plain text mixed with formatting commands and produces formatted
    output.

    Luis Anaya and Nicolas Goaziou implemented ~ox-groff.el~ to allow
    conversion from Org files to groff.

*** ~ox-koma-letter.el~ by Nicolas Goaziou and Alan Schmitt

    This back-end allow to export Org pages to the =KOMA Scrlttr2= format.

*** ~ox-rss.el~ by Bastien

    This back-end lets you export Org pages to RSS 2.0 feeds.  Combined
    with the HTML publishing feature, this allows you to build a blog
    entirely with Org.

** New features

*** Export

**** New export generic options

If you use Org exporter, we advise you to re-read [[https://orgmode.org/org.html#Exporting][the manual section about
it]].  It has been updated and includes new options.

Among the new/updated export options, three are of particular importance:

- [[doc:org-export-allow-bind-keywords][org-export-allow-bind-keywords]] :: This option replaces the old option
     =org-export-allow-BIND= and the default value is =nil=, not =confirm=.
     You will need to explicitly set this to =t= in your initialization
     file if you want to allow =#+BIND= keywords.

- [[doc:org-export-with-planning][org-export-with-planning]] :: This new option controls the export of
     =SCHEDULED:, DEADLINE:, CLOSED:= lines, and planning information is
     now skipped by default during export.  This use to be the job of
     [[doc:org-export-with-timestamps][org-export-with-timestamps]], but this latter option has been given a
     new role: it controls the export of /standalone time-stamps/.  When
     set to =nil=, Org will not export active and inactive time-stamps
     standing on a line by themselves or within a paragraph that only
     contains time-stamps.

To check if an option has been introduced or its default value changed in
Org 8.0, do =C-h v [option] RET= and check if the documentation says that
the variable has been introduced (or changed) in version 24.4 of Emacs.

**** Enhanced default stylesheet for the HTML exporter

See the new default value of [[doc:org-html-style-default][org-html-style-default]].

**** New tags, classes and ids for the HTML exporter

See the new default value of [[doc:org-html-divs][org-html-divs]].

**** Support for tikz pictures in LaTeX export
**** ~org-man.el~: New export function for "man" links
**** ~org-docview.el~: New export function for docview links
*** Structure editing

**** =C-u C-u M-RET= inserts a heading at the end of the parent subtree
**** Cycling to the =CONTENTS= view keeps inline tasks folded

[[doc:org-cycle-hook][org-cycle-hook]] as a new function [[doc:org-cycle-hide-inline-tasks][org-cycle-hide-inline-tasks]] which
prevents the display of inline tasks when showing the content of a subtree.

**** =C-c -= in a region makes a list item for each line

This is the opposite of the previous behavior, where =C-c -= on a region
would create one item for the whole region, and where =C-u C-c -= would
create an item for each line.  Now =C-c -= on the selected region creates
an item per line, and =C-u C-c -= creates a single item for the whole
region.

**** When transposing words, markup characters are now part of the words

In Emacs, you can transpose words with =M-t=.  Transposing =*these*
_words__= will preserve markup.

**** New command [[doc:org-set-property-and-value][org-set-property-and-value]] bound to =C-c C-x P=

This command allows you to quickly add both the property and its value.  It
is useful in buffers where there are many properties and where =C-c C-x p=
can slow down the flow of editing too much.

**** New commands [[doc:org-next-block][org-next-block]] and [[doc:org-previous-block][org-previous-block]]

These commands allow you to go to the previous block (=C-c M-b= or the
speedy key =B=) or to the next block (=C-c M-f= or the speedy key =F=.)

**** New commands [[doc:org-drag-line-forward][org-drag-line-forward]] and [[doc:org-drag-line-backward][org-drag-line-backward]]

These commands emulate the old behavior of =M-<down>= and =M-<up>= but are
now bound to =S-M-<down>= and =S-M-<up>= respectively, since =M-<down>= and
=M-<up>= now drag the whole element at point (a paragraph, a table, etc.)
forward and backward.

**** When a list item has a checkbox, inserting a new item uses a checkbox too
**** When sorting entries/items, only the description of links is considered

Now Org will sort this list

: - [[https://abc.org][B]]
: - [[https://def.org][A]]

like this:

: - [[https://def.org][A]]
: - [[https://abc.org][B]]

by comparing the descriptions, not the links.
Same when sorting headlines instead of list items.
**** New option =orgstruct-heading-prefix-regexp=

For example, setting this option to "^;;; " in Emacs lisp files and using
=orgstruct-mode= in those files will allow you to cycle through visibility
states as if lines starting with ";;; *..." where headlines.

In general, you want to set =orgstruct-heading-prefix-regexp= as a file
local variable.

**** New behavior of [[doc:org-clone-subtree-with-time-shift][org-clone-subtree-with-time-shift]]

The default is now to ask for a time-shift only when there is a time-stamp.
When called with a universal prefix argument =C-u=, it will not ask for a
time-shift even if there is a time-stamp.

**** New option [[doc:org-agenda-restriction-lock-highlight-subtree][org-agenda-restriction-lock-highlight-subtree]]

This defaults to =t= so that the whole subtree is highlighted when you
restrict the agenda view to it with =C-c C-x <= (or the speed command =<=).
The default setting helps ensuring that you are not adding tasks after the
restricted region.  If you find this highlighting too intrusive, set this
option to =nil=.
**** New option [[doc:org-closed-keep-when-no-todo][org-closed-keep-when-no-todo]]

When switching back from a =DONE= keyword to a =TODO= keyword, Org now
removes the =CLOSED= planning information, if any.  It also removes this
information when going back to a non-TODO state (e.g., with =C-c C-t SPC=).
If you want to keep the =CLOSED= planning information when removing the
TODO keyword, set [[doc:org-closed-keep-when-no-todo][org-closed-keep-when-no-todo]] to =t=.

**** New option [[doc:org-image-actual-width][org-image-actual-width]]

This option allows you to change the width of in-buffer displayed images.
The default is to use the actual width of the image, but you can use a
fixed value for all images, or fall back on an attribute like

: #+attr_html: :width 300px
*** Scheduled/deadline

**** Implement "delay" cookies for scheduled items

If you want to delay the display of a scheduled task in the agenda, you can
now use a delay cookie like this: =SCHEDULED: <2004-12-25 Sat -2d>=.  The
task is still scheduled on the 25th but will appear in your agenda starting
from two days later (i.e. from March 27th.)

Imagine for example that your co-workers are not done in due time and tell
you "we need two more days".  In that case, you may want to delay the
display of the task in your agenda by two days, but you still want the task
to appear as scheduled on March 25th.

In case the task contains a repeater, the delay is considered to affect all
occurrences; if you want the delay to only affect the first scheduled
occurrence of the task, use =--2d= instead.  See [[doc:org-scheduled-delay-days][org-scheduled-delay-days]]
and [[doc:org-agenda-skip-scheduled-delay-if-deadline][org-agenda-skip-scheduled-delay-if-deadline]] for details on how to
control this globally or per agenda.

**** Use =C-u C-u C-c C-s= will insert a delay cookie for scheduled tasks

See the previous section for why delay cookies may be useful.

**** Use =C-u C-u C-c C-d= will insert a warning delay for deadline tasks

=C-u C-u C-c C-d= now inserts a warning delay to deadlines.
*** Calendar, diary and appts

**** New variable [[doc:org-read-date-minibuffer-local-map][org-read-date-minibuffer-local-map]]

By default, this new local map uses "." to go to today's date, like in the
normal =M-x calendar RET=.  If you want to deactivate this and to reassign
the "@" key to =calendar-goto-today=, use this:

#+BEGIN_SRC emacs-lisp
  ;; Unbind "." in Org's calendar:
  (define-key org-read-date-minibuffer-local-map (kbd ".") nil)

  ;; Bind "@" to `calendar-goto-today':
  (define-key org-read-date-minibuffer-local-map
              (kbd "@")
              (lambda () (interactive) (org-eval-in-calendar '(calendar-goto-today))))
#+END_SRC

**** In Org's calendar, =!= displays diary entries of the date at point

This is useful when you want to check if you don't already have an
appointment when setting new ones with =C-c .= or =C-c s=.  =!= will
call =diary-view-entries= and display the diary in a separate buffer.

**** [[doc:org-diary][org-diary]]: only keep the descriptions of links

[[doc:org-diary][org-diary]] returns diary information from Org files, but it returns it
in a diary buffer, not in an Org mode buffer.  When links are displayed,
only show their description, not the full links.
*** Agenda

**** New agenda type =agenda*= and entry types =:scheduled* :deadline*=

When defining agenda custom commands, you can now use =agenda*=: this will
list entries that have both a date and a time.  This is useful when you
want to build a list of appointments.

You can also set [[doc:org-agenda-entry-types][org-agenda-entry-types]] either globally or locally in
each agenda custom command and use =:timestamp*= and/or =:deadline*= there.

Another place where this is useful is your =.diary= file:

: %%(org-diary :scheduled*) ~/org/rdv.org

This will list only entries from =~/org/rdv.org= that are scheduled with a
time value (i.e. appointments).

**** New agenda sorting strategies

[[doc:org-agenda-sorting-strategy][org-agenda-sorting-strategy]] allows these new sorting strategies:

| Strategy       | Explanations                             |
|----------------+------------------------------------------|
| timestamp-up   | Sort by any timestamp, early first       |
| timestamp-down | Sort by any timestamp, late first        |
| scheduled-up   | Sort by scheduled timestamp, early first |
| scheduled-down | Sort by scheduled timestamp, late first  |
| deadline-up    | Sort by deadline timestamp, early first  |
| deadline-down  | Sort by deadline timestamp, late first   |
| ts-up          | Sort by active timestamp, early first    |
| ts-down        | Sort by active timestamp, late first     |
| tsia-up        | Sort by inactive timestamp, early first  |
| tsia-down      | Sort by inactive timestamp, late first   |

**** New options to limit the number of agenda entries

You can now limit the number of entries in an agenda view.  This is
different from filters: filters only /hide/ the entries in the agenda,
while limits are set while generating the list of agenda entries.

These new options are available:

- [[doc:org-agenda-max-entries][org-agenda-max-entries]] :: limit by number of entries.
- [[doc:org-agenda-max-todos][org-agenda-max-todos]] :: limit by number of TODOs.
- [[doc:org-agenda-max-tags][org-agenda-max-tags]] :: limit by number of tagged entries.
- [[doc:org-agenda-max-effort][org-agenda-max-effort]] :: limit by effort (minutes).

For example, if you locally set [[doc:org-agenda-max-todos][org-agenda-max-todos]] to 3 in an agenda
view, the agenda will be limited to the first three todos.  Other entries
without a TODO keyword or beyond the third TODO headline will be ignored.

When setting a limit (e.g. about an effort's sum), the default behavior is
to exclude entries that cannot be checked against (e.g. entries that have
no effort property.)  To include other entries too, you can set the limit
to a negative number.  For example =(setq org-agenda-max-tags -3)= will not
show the fourth tagged headline (and beyond), but it will also show
non-tagged headlines.

**** =~= in agenda view sets temporary limits

You can hit =~= in the agenda to temporarily set limits: this will
regenerate the agenda as if the limits were set.  This is useful for
example when you want to only see a list of =N= tasks, or a list of tasks
that take only =N= minutes.

**** "=" in agenda view filters by regular expressions

You can now filter agenda entries by regular expressions using ~=~.  =C-u
== will filter entries out.  Regexp filters are cumulative.  You can set
[[doc:org-agenda-regexp-filter-preset][org-agenda-regexp-filter-preset]] to suit your needs in each agenda view.

**** =|= in agenda view resets all filters

Since it's common to combine tag filters, category filters, and now regexp
filters, there is a new command =|= to reset all filters at once.

**** Allow writing an agenda to an =.org= file

You can now write an agenda view to an =.org= file.  It copies the
headlines and their content (but not subheadings) into the new file.

This is useful when you want to quickly share an agenda containing the full
list of notes.

**** New commands to drag an agenda line forward (=M-<down>=) or backward (=M-<up>=)

It sometimes handy to move agenda lines around, just to quickly reorganize
your tasks, or maybe before saving the agenda to a file.  Now you can use
=M-<down>= and =M-<up>= to move the line forward or backward.

This does not persist after a refresh of the agenda, and this does not
change the =.org= files who contribute to the agenda.

**** Use =%b= for displaying "breadcrumbs" in the agenda view

[[doc:org-agenda-prefix-format][org-agenda-prefix-format]] now allows to use a =%b= formatter to tell Org
to display "breadcrumbs" in the agenda view.

This is useful when you want to display the task hierarchy in your agenda.

**** Use =%l= for displaying the headline's level in the agenda view

[[doc:org-agenda-prefix-format][org-agenda-prefix-format]] allows to use a =%l= formatter to tell Org to
display entries with additional spaces corresponding to their level in the
outline tree.

**** [[doc:org-agenda-write][org-agenda-write]] will ask before overwriting an existing file

=M-x org-agenda-write RET= (or =C-c C-w= from an agenda buffer) used to
overwrite preexisting file with the same name without confirmation.  It now
asks for a confirmation.

**** New commands =M-m= and =M-*= to toggle (all) mark(s) for bulk action

- [[doc:org-agenda-bulk-toggle][org-agenda-bulk-toggle]] :: this command is bound to =M-m= and toggles
     the mark of the entry at point.

- [[doc:org-agenda-bulk-toggle-all][org-agenda-bulk-toggle-all]] :: this command is bound to =M-*= and
     toggles all the marks in the current agenda.

**** New option [[doc:org-agenda-search-view-max-outline-level][org-agenda-search-view-max-outline-level]]

This option sets the maximum outline level to display in search view.
E.g. when this is set to 1, the search view will only show headlines of
level 1.

**** New option [[doc:org-agenda-todo-ignore-time-comparison-use-seconds][org-agenda-todo-ignore-time-comparison-use-seconds]]

This allows to compare times using seconds instead of days when honoring
options like =org-agenda-todo-ignore-*= in the agenda display.

**** New option [[doc:org-agenda-entry-text-leaders][org-agenda-entry-text-leaders]]

This allows you to get rid of the ">" character that gets added in front of
entries excerpts when hitting =E= in the agenda view.

**** New formatting string for past deadlines in [[doc:org-agenda-deadline-leaders][org-agenda-deadline-leaders]]

The default formatting for past deadlines is ="%2d d. ago: "=, which makes
it explicit that the deadline is in the past.  You can configure this via
[[doc:org-agenda-deadline-leaders][org-agenda-deadline-leaders]].  Note that the width of the formatting
string is important to keep the agenda alignment clean.

**** New allowed value =repeated-after-deadline= for [[doc:org-agenda-skip-scheduled-if-deadline-is-shown][org-agenda-skip-scheduled-if-deadline-is-shown]]

When [[doc:org-agenda-skip-scheduled-if-deadline-is-shown][org-agenda-skip-scheduled-if-deadline-is-shown]] is set to
=repeated-after-deadline=, the agenda will skip scheduled items if they are
repeated beyond the current deadline.

**** New option for [[doc:org-agenda-skip-deadline-prewarning-if-scheduled][org-agenda-skip-deadline-prewarning-if-scheduled]]

This variable may be set to nil, t, the symbol `pre-scheduled', or a number
which will then give the number of days before the actual deadline when the
prewarnings should resume.  The symbol `pre-scheduled' eliminates the
deadline prewarning only prior to the scheduled date.

Read the full docstring for details.

**** [[doc:org-class][org-class]] now supports holiday strings in the skip-weeks parameter

For example, this task will now be skipped only on new year's day:

    : * Task
    :   <%%(org-class 2012 1 1 2013 12 12 2 "New Year's Day")>
*** Capture

**** Allow =C-1= as a prefix for [[doc:org-agenda-capture][org-agenda-capture]] and [[doc:org-capture][org-capture]]

With a =C-1= prefix, the capture mechanism will use the =HH:MM= value at
point (if any) or the current =HH:MM= time as the default time for the
capture template.

**** Expand keywords within %(sexp) placeholder in capture templates

If you use a =%:keyword= construct within a =%(sexp)= construct, Org will
expand the keywords before expanding the =%(sexp)=.

**** Allow to contextualize capture (and agenda) commands by checking the name of the buffer

[[doc:org-capture-templates-contexts][org-capture-templates-contexts]] and [[doc:org-agenda-custom-commands-contexts][org-agenda-custom-commands-contexts]]
allow you to define what capture templates and what agenda commands should
be available in various contexts.  It is now possible for the context to
check against the name of the buffer.
*** Tag groups

Using =#+TAGS: { Tag1 : Tag2 Tag3 }= will define =Tag1= as a /group tag/
(note the colon after =Tag1=).  If you search for =Tag1=, it will return
headlines containing either =Tag1=, =Tag2= or =Tag3= (or any combination
of those tags.)

You can use group tags for sparse tree in an Org buffer, for creating
agenda views, and for filtering.

See https://orgmode.org/org.html#Tag-groups for details.

*** Links

**** =C-u C-u M-x org-store-link RET= will ignore non-core link functions

Org knows how to store links from Org buffers, from info files and from
other Emacs buffers.  Org can be taught how to store links from any buffer
through new link protocols (see [[https://orgmode.org/org.html#Adding-hyperlink-types]["Adding hyperlink types"]] in the manual.)

Sometimes you want Org to ignore added link protocols and store the link
as if the protocol was not known.

You can now do this with =C-u C-u M-x org-store-link RET=.

**** =C-u C-u C-u M-x org-store-link RET= on an active region will store links for each lines

Imagine for example that you want to store a link for every message in a
Gnus summary buffer.  In that case =C-x h C-u C-u C-u M-x org-store-link
RET= will store a link for every line (i.e. message) if the region is
active.

**** =C-c C-M-l= will add a default description for links which don't have one

=C-c C-M-l= inserts all stored links.  If a link does not have a
description, this command now adds a default one, so that we are not mixing
with-description and without-description links when inserting them.

**** No curly braces to bracket links within internal links

When storing a link to a headline like

: * See [[https://orgmode.org][Org website]]

[[doc:org-store-link][org-store-link]] used to convert the square brackets into curly brackets.
It does not anymore, taking the link description or the link path, when
there is no description.
*** Table

**** Switching between #+TBLFM lines

If you have several =#+TBLFM= lines below a table, =C-c C-c= on a line will
apply the formulas from this line, and =C-c C-c= on another line will apply
those other formulas.

**** You now use "nan" for empty fields in Calc formulas

If empty fields are of interest, it is recommended to reread the section
[[https://orgmode.org/org.html#Formula-syntax-for-Calc][3.5.2 Formula syntax for Calc]] of the manual because the description for the
mode strings has been clarified and new examples have been added towards
the end.

**** Handle localized time-stamps in formulas evaluation

If your =LOCALE= is set so that Org time-stamps use another language than
english, and if you make time computations in Org's table, it now works by
internally converting the time-stamps with a temporary =LOCALE=C= before
doing computation.

**** New lookup functions

There are now three lookup functions:

- [[doc:org-lookup-first][org-lookup-first]]
- [[doc:org-lookup-last][org-lookup-last]]
- [[doc:org-lookup-all][org-lookup-all]]

See [[https://orgmode.org/org.html#Lookup-functions][the manual]] for details.
*** Startup keywords

These new startup keywords are now available:

| Startup keyword                  | Option                                      |
|----------------------------------+---------------------------------------------|
| =#+STARTUP: logdrawer=           | =(setq org-log-into-drawer t)=              |
| =#+STARTUP: nologdrawer=         | =(setq org-log-into-drawer nil)=            |
|----------------------------------+---------------------------------------------|
| =#+STARTUP: logstatesreversed=   | =(setq org-log-states-order-reversed t)=    |
| =#+STARTUP: nologstatesreversed= | =(setq org-log-states-order-reversed nil)=  |
|----------------------------------+---------------------------------------------|
| =#+STARTUP: latexpreview=        | =(setq org-startup-with-latex-preview t)=   |
| =#+STARTUP: nolatexpreview=      | =(setq org-startup-with-latex-preview nil)= |

*** Clocking

**** New option [[doc:org-clock-rounding-minutes][org-clock-rounding-minutes]]

E.g. if [[doc:org-clock-rounding-minutes][org-clock-rounding-minutes]] is set to 5, time is 14:47 and you
clock in: then the clock starts at 14:45.  If you clock out within the next
5 minutes, the clock line will be removed; if you clock out 8 minutes after
your clocked in, the clock out time will be 14:50.

**** New option [[doc:org-time-clocksum-use-effort-durations][org-time-clocksum-use-effort-durations]]

When non-nil, =C-c C-x C-d= uses effort durations.  E.g., by default, one
day is considered to be a 8 hours effort, so a task that has been clocked
for 16 hours will be displayed as during 2 days in the clock display or in
the clocktable.

See [[doc:org-effort-durations][org-effort-durations]] on how to set effort durations and
[[doc:org-time-clocksum-format][org-time-clocksum-format]] for more on time clock formats.

**** New option [[doc:org-clock-x11idle-program-name][org-clock-x11idle-program-name]]

This allows to set the name of the program which prints X11 idle time in
milliseconds.  The default is to use =x11idle=.

**** New option [[doc:org-use-last-clock-out-time-as-effective-time][org-use-last-clock-out-time-as-effective-time]]

When non-nil, use the last clock out time for [[doc:org-todo][org-todo]].  Note that this
option has precedence over the combined use of [[doc:org-use-effective-time][org-use-effective-time]] and
[[doc:org-extend-today-until][org-extend-today-until]].

**** =S-<left/right>= on a clocksum column will update the sum by updating the last clock
**** =C-u 3 C-S-<up/down>= will update clock timestamps synchronously by 3 units
**** New parameter =:wstart= for clocktables to define the week start day
**** New parameter =:mstart= to state the starting day of the month
**** Allow relative times in clocktable tstart and tend options
**** The clocktable summary is now a caption
**** =:tstart= and =:tend= and friends allow relative times like "<-1w>" or "<now>"
*** Babel

**** You can now use =C-c C-k= for [[doc:org-edit-src-abort][org-edit-src-abort]]

This allows you to quickly cancel editing a source block.

**** =C-u C-u M-x org-babel-tangle RET= tangles by the target file of the block at point

This is handy if you want to tangle all source code blocks that have the
same target than the block at point.

**** New options for auto-saving the base buffer or the source block editing buffer

When [[doc:org-edit-src-turn-on-auto-save][org-edit-src-turn-on-auto-save]] is set to =t=, editing a source block
in a new window will turn on =auto-save-mode= and save the code in a new
file under the same directory than the base Org file.

When [[doc:org-edit-src-auto-save-idle-delay][org-edit-src-auto-save-idle-delay]] is set to a number of minutes =N=,
the base Org buffer will be saved after this number of minutes of idle
time.

**** New =:post= header argument post-processes results

     This header argument may be used to pass the results of the current
     code block through another code block for post-processing.  See the
     manual for a usage example.

**** Commented out heading are ignored when collecting blocks for tangling

If you comment out a heading (with =C-c ;= anywhere on the heading or in
the subtree), code blocks from within this heading are now ignored when
collecting blocks for tangling.

**** New option [[doc:org-babel-hash-show-time][org-babel-hash-show-time]] to show a time-stamp in the result hash
**** Do not ask for confirmation if cached value is current

Do not run [[doc:org-babel-confirm-evaluate][org-babel-confirm-evaluate]] if source block has a cache and the
cache value is current as there is no evaluation involved in this case.
**** =ob-sql.el= and =ob-python.el= have been improved.
**** New Babel files only need to =(require 'ob)=

When writing a new Babel file, you now only need to use =(require 'ob)=
instead of requiring each Babel library one by one.
*** Faces

- Org now fontifies radio link targets by default
- In the agenda, use [[doc:org-todo-keyword-faces][org-todo-keyword-faces]] to highlight selected TODO keywords
- New face [[doc:org-priority][org-priority]], enhanced fontification of priority cookies in agenda

** Outside Org

*** Spanish translation of the Org guide by David Arroyo Menéndez

David (and others) translated the Org compact guide in spanish:

You can read the [[https://orgmode.org/worg/orgguide/orgguide.es.pdf][PDF guide]].

*** ~poporg.el~ and ~outorg.el~

Two new libraries (~poporg.el~ by François Pinard and ~outorg.el~ by
Thorsten Jolitz) now enable editing of comment-sections from source-code
buffers in temporary Org-mode buffers, making the full editing power of
Org-mode available.  ~outorg.el~ comes together with ~outshine.el~ and
~navi-mode.el~, two more libraries by Thorsten Jolitz with the goal to give
source-code buffers the /look & feel/ of Org-mode buffers while greatly
improving navigation and structure editing.  A detailed description can be
found here: https://orgmode.org/worg/org-tutorials/org-outside-org.html

Here are two screencasts demonstrating Thorsten's tools:

- [[https://youtu.be/nqE6YxlY0rw]["Modern conventions for Emacs Lisp files"]]
- [[https://www.youtube.com/watch?v%3DII-xYw5VGFM][Exploring Bernt Hansen's Org-mode tutorial with 'navi-mode']]

*** MobileOrg for iOS

MobileOrg for iOS back in the App Store The 1.6.0 release was focused on
the new Dropbox API and minor bug fixes but also includes a new ability to
launch in Capture mode.  Track development and contribute [[https://github.com/MobileOrg/mobileorg/issues][on github]].

* Version 7.9.3

** New option [[doc::org-agenda-use-tag-inheritance][org-agenda-use-tag-inheritance]]

[[doc::org-use-tag-inheritance][org-use-tag-inheritance]] controls whether tags are inherited when
org-tags-view is called (either in =tags=, =tags-tree= or =tags-todo=
agenda views.)

When generating other agenda types such as =agenda=, =todo= and
=todo-tree=, tags inheritance is not used when selecting the entries
to display.  Still, you might want to have all tag information correct
in the agenda buffer, e.g. for tag filtering.  In that case, add the
agenda type to this variable.

Setting this variable to nil should considerably speeds up the agenda
generation.

Note that the default was to display inherited tags in the agenda
lines even if `org-use-tag-inheritance' was nil.  The default is now
to *never* display inherited tags in agenda lines, but to /know/ about
them when the agenda type is listed in [[doc::org-agenda-use-tag-inheritance][org-agenda-use-tag-inheritance]].

** New default value =nil= for [[doc::org-agenda-dim-blocked-tasks][org-agenda-dim-blocked-tasks]]

Using `nil' as the default value speeds up the agenda generation.  You
can hit `#' (or `C-u #') in agenda buffers to temporarily dim (or turn
invisible) blocked tasks.

** New speedy keys for [[doc::org-speed-commands-default][org-speed-commands-default]]

You can now use `:' (instead of `;') for setting tags---this is
consistent with using the `:' key in agenda view.

You can now use `=' for [[doc::org-columns][org-columns]].

** =org-float= is now obsolete, use =diary-float= instead
** No GPL manual anymore

There used to be a GPL version of the Org manual, but this is not the
case anymore, the Free Software Foundation does not permit this.

The GNU FDL license is now included in the manual directly.

** Enhanced compatibility with Emacs 22 and XEmacs

Thanks to Achim for his work on enhancing Org's compatibility with
various Emacsen.  Things may not be perfect, but Org should work okay
in most environments.

* Version 7.9.2

** New ELPA repository for Org packages

You can now add the Org ELPA repository like this:

#+BEGIN_SRC emacs-lisp
(add-to-list 'package-archives '("org" . "https://orgmode.org/elpa/") t)
#+END_SRC

It contains both the =org-*.tar= package (the core Org distribution, also
available through https://elpa.gnu.org) and the =org-plus*.tar= package (the
extended Org distribution, with non-GNU packages from the =contrib/=
directory.)

See https://orgmode.org/elpa/

** Overview of the new keybindings

   | Keybinding      | Speedy | Command                     |

** New package and Babel language

*** =org-eshell.el= by Konrad Hinsen is now in Org

    =org-eshell.el= allows you to create links from [[https://www.gnu.org/software/emacs/manual/html_node/eshell/index.html][Eshell]].

*** Support for execution of Scala code blocks (see ob-scala.el)
*** Support for execution of IO code blocks (see ob-io.el)

** Incompatible changes

   - If your code relies on =org-write-agenda=, please use
     [[doc::org-agenda-write][org-agenda-write]] from now on.

   - If your code relies on =org-make-link=, please use =concat=
     instead.

   - =org-link-to-org-use-id= has been renamed to
     =org-id-link-to-org-use-id= and its default value is nil.  The
     previous default was =create-if-interactive-and-no-custom-id=.

** New features and user-visible changes

*** Org Element

    =org-element.el= is a toolbox for parsing and analyzing "elements"
    in an Org-mode buffer.  This has been written by Nicolas Goaziou
    and has been tested for quite some time.  It is now part of Org's
    core and many core functions rely on this package.

    Two functions might be particularly handy for users:
    =org-element-at-point= and =org-element-context=.

    See the docstrings for more details.

    Below is a list of editing and navigating commands that now rely
    on =org-element.el=.

**** [[doc::org-fill-paragraph][org-fill-paragraph]] has been completely rewritten

     The filling mechanisms now rely on org-element, trying to do the
     right thing on each element in various contexts.  E.g. filling in
     a list item will preserve indentation; filling in message-mode
     will fall back on the relevant filling functions; etc.

**** [[doc::org-metaup][org-metaup]] and [[doc::org-metadown][org-metadown]] will drag the element backward/forward

     If you want to get the old behavior (i.e. moving a line up and
     down), you can first select the line as an active region, then
     =org-metaup= or =org-metadown= to move the region backward or
     forward.  This also works with regions bigger than just one line.

**** [[doc::org-up-element][org-up-element]] and [[doc::org-down-element][org-down-element]] (respectively =C-c C-^= and =C-c C-_=)

     This will move the point up/down in the hierarchy of elements.

**** [[doc::org-backward-element][org-backward-element]] and [[doc::org-forward-element][org-forward-element]] (respectively =M-{= and =M-}=)

     This will move the point backward/forward in the hierarchy of
     elements.

**** [[doc::org-narrow-to-element][org-narrow-to-element]] will narrow to the element at point
**** [[doc::org-mark-element][org-mark-element]] will mark the element at point

     This command is bound to =M-h= and will mark the element at
     point.  If the point is at a paragraph, it will mark the
     paragraph.  If the point is at a list item, it will mark the list
     item.  Etc.

     Note that if point is at the beginning of a list, it will mark
     the whole list.

     To mark a subtree, you can either use =M-h= on the headline
     (since there is no ambiguity about the element you're at) or
     [[doc::org-mark-subtree][org-mark-subtree]] (=C-c @=) anywhere in the subtree.

     Invoking [[doc::org-mark-element][org-mark-element]] repeatedly will try to mark the next
     element on top of the previous one(s).  E.g. hitting =M-h= twice
     on a headline will mark the current subtree and the next one on
     the same level.

*** Org Agenda

**** New option [[doc::org-agenda-sticky][org-agenda-sticky]]

     There is a new option =org-agenda-sticky= which enables "sticky"
     agendas.  Sticky agendas remain opened in the background so that
     you don't need to regenerate them each time you hit the
     corresponding keystroke.  This is a big time saver.

     When [[doc::org-agenda-sticky][org-agenda-sticky]] is =non-nil=, the agenda buffer will be
     named using the agenda key and its description.  In sticky
     agendas, the =q= key will just bury the agenda buffers and
     further agenda commands will show existing buffer instead of
     generating new ones.

     If [[doc::org-agenda-sticky][org-agenda-sticky]] is set to =nil=, =q= will kill the single
     agenda buffer.

**** New option [[doc::org-agenda-custom-commands-contexts][org-agenda-custom-commands-contexts]]

     Setting this option allows you to define specific context where
     agenda commands should be available from.  For example, when set
     to this value

     #+BEGIN_SRC emacs-lisp
  (setq org-agenda-custom-commands-contexts
        '(("p" (in-file . "\\.txt"))))
#+END_SRC

     then the =p= agenda command will only be available from buffers
     visiting *.txt files.  See the docstring and the manual for more
     details on how to use this.

**** Changes in bulk actions

     The set of commands starting with =k ...= as been deleted and the
     features have been merged into the "bulk action" feature.

     After you marked some entries in the agenda, if you call =B s=,
     the agenda entries will be rescheduled using the date at point if
     on a date header.  If you are on an entry with a timestamp, you
     will be prompted for a date to reschedule your marked entries to,
     using the timestamp at point as the default prompt.

     You can now use =k= to capture the marked entry and use the date
     at point as an overriding date for the capture template.

     To bind this behavior to =M-x org-capture RET= (or its
     keybinding), set the new option [[doc::org-capture-use-agenda-date][org-capture-use-agenda-date]] to
     =t=.

**** =N= and =P= in the agenda will move to the next/previous item

**** New command [[doc::org-agenda-bulk-mark-all][org-agenda-bulk-mark-all]] to mark all items

     This new command is bound to =*= in agenda mode.

     There is also a new option [[doc::org-agenda-bulk-mark-char][org-agenda-bulk-mark-char]] to set the
     character to use as a mark for bulk actions.

**** New option [[doc::org-agenda-persistent-marks][org-agenda-persistent-marks]]

     When set to =non-nil=, marks will remain visible after a bulk
     action.  You can temporarily toggle this by pressing =p= when
     invoking [[doc::org-agenda-bulk-action][org-agenda-bulk-action]].  Marks are deleted if your
     rebuild the agenda buffer or move to another date/span (e.g. with
     =f= or =w=).

**** New option [[doc::org-agenda-skip-timestamp-if-deadline-is-shown][org-agenda-skip-timestamp-if-deadline-is-shown]]

     =Non-nil= means skip timestamp line if same entry shows because
     of deadline.

     In the agenda of today, an entry can show up multiple times
     because it has both a plain timestamp and has a nearby deadline.
     When this variable is t, then only the deadline is shown and the
     fact that the entry has a timestamp for or including today is not
     shown.  When this variable is =nil=, the entry will be shown
     several times.

**** New =todo-unblocked= and =nottodo-unblocked= skip conditions

     See the [[https://orgmode.org/cgit.cgi/org-mode.git/commit/?id=f426da][git commit]] for more explanations.

**** Allow category filtering in the agenda

     You can now filter the agenda by category.  Pressing "<" will
     filter by the category of the item on the current line, and
     pressing "<" again will remove the filter.  You can combine tag
     filters and category filters.

     You can use =org-agenda-category-filter= in your custom agenda
     views and =org-agenda-category-filter-preset= in your main
     configuration.

     See also the new command [[doc::org-agenda-filter-by-top-category][org-agenda-filter-by-top-category]]:
     hitting =^= will filter by "Top" category: only show entries that
     are of the same category than the Top category of the entry at
     point.

*** Org Links

**** Inserting links

     When inserting links through [[doc::org-insert-link][org-insert-link]], the description is
     now displayed first, followed by the literal link, as the
     description is often more useful when you look for the link you
     want to insert.

     Completion now complete both literal links and description.  If
     you complete a description, the literal link and its description
     will be inserted directly, whereas when you complete the literal
     link, you will be prompted for a description (as with Org 7.8.)

     In the completion buffer, links to the current buffer are now
     highlighted.

**** New templates =%h= and =%(sexp)= for abbreviated links

     On top of =%s= template, which is replaced by the link tag in
     abbreviated links, you can now use =%h= (which does the same than =%s=
     but does not hexify the tag) and =%(sexp)= (which can run a function
     that takes the tag as its own argument.)

**** New link type =help=

     You can now create links from =help= buffers.

     For example, if you request help for the command [[doc::org-agenda][org-agenda]] with
     =C-h f org-agenda RET=, creating a link from this buffer will let
     you go back to the same buffer.

**** New command [[doc::org-insert-all-links][org-insert-all-links]]

     This will insert all links as list items.  With a universal
     prefix argument, links will not be deleted from the variable
     =org-stored-links=.

     This new command is bound to =C-c C-M-l=.

**** New option [[doc::org-url-hexify-p][org-url-hexify-p]]

     When set to =nil=, the =URL= part of a link will not be hexified.

**** Org can now open multiple shell links

**** New option [[doc::org-doi-server-url][org-doi-server-url]] to specify an alternate DOI server

**** RET now follows time stamps links

*** Org Editing

**** [[doc::org-todo][org-todo]] and =org-archive-*= can now loop in the active region

     When [[doc::org-loop-over-headlines-in-active-region][org-loop-over-headlines-in-active-region]] is =non-nil=, using
     [[doc::org-todo][org-todo]] or =org-archive-*= commands in the active region will
     loop over headlines.  This is handy if you want to set the TODO
     keyword for several items, or archive them quickly.

**** You can now set tags for headlines in a region

     If [[doc::org-loop-over-headlines-in-active-region][org-loop-over-headlines-in-active-region]] is =non-nil=, then
     selecting the region and hitting =C-c C-q= will set the tags for
     all headlines in the region.

**** New command [[doc::org-insert-drawer][org-insert-drawer]] to insert a drawer interactively

**** Comments start with "^[ \t]*# " anywhere on a line

     Note that the space after the hashtag is mandatory.  Comments
     with "^#+" are not supported anymore.

**** New speed key =#= to toggle the COMMENT cookie on a headline

**** =indent-region-function= is now set to [[doc::org-indent-region][org-indent-region]]

     =C-M-\= should now produce useful results.

     You can unindent the buffer with [[doc::org-unindent-buffer][org-unindent-buffer]].

**** New option [[doc::org-allow-promoting-top-level-subtree][org-allow-promoting-top-level-subtree]]

     When =non-nil=, =S-M-<left>= will promote level-1 subtrees
     containing other subtrees.  The level-1 headline will be
     commented out.  You can revert to the previous state with =M-x
     undo RET=.

*** Org Clock

**** New keybinding =C-c C-x C-z= for [[doc::org-clock-resolve][org-clock-resolve]]

**** New keybinding =C-c C-x C-q= for [[doc::org-clock-cancel][org-clock-cancel]]

**** New command [[doc::org-clock-in-last][org-clock-in-last]] to clock in the last clocked item

     This command is bound to =C-c C-x C-x= and will clock in the last
     clocked entry, if any.

**** =C-u M-x= [[doc::org-clock-out][org-clock-out]] =RET= now prompts for a state to switch to

**** =S-M-<up/down>= on a clock timestamps adjusts the previous/next clock

**** New option [[doc::org-clock-continuously][org-clock-continuously]]

     When set to =nil=, clocking in a task will first try to find the
     last clocked out task and restart from when that task was clocked
     out.

     You can temporarily activate continuous clocking with =C-u C-u
     C-u M-x= [[doc::org-clock-in][org-clock-in]] =RET= (three universal prefix arguments)
     and =C-u C-u M-x= [[doc::org-clock-in-last][org-clock-in-last]] =RET= (two universal prefix
     arguments).


**** New option [[doc::org-clock-frame-title-format][org-clock-frame-title-format]]

     This option sets the value of =frame-title-format= when clocking
     in.

**** New options for controlling the clockreport display

     [[doc::org-clock-file-time-cell-format][org-clock-file-time-cell-format]]: Format string for the file time
     cells in clockreport.

     [[doc::org-clock-total-time-cell-format][org-clock-total-time-cell-format]]: Format string for the total
     time cells in clockreport.


**** New options for controlling the clock/timer display

     [[doc::org-clock-clocked-in-display][org-clock-clocked-in-display]]: control whether the current clock
     is displayed in the mode line and/or frame title.

     [[doc::org-timer-display][org-timer-display]]: control whether the current timer is displayed
     in the mode line and/or frame title.

     This allows the clock and timer to be displayed in the frame
     title instead of, or as well as, the mode line.  This is useful
     for people with limited space in the mode line but with ample
     space in the frame title.

*** Org Appearance

**** New option [[doc::org-custom-properties][org-custom-properties]]

     The visibility of properties listed in this options can be turn
     on/off with [[doc::org-toggle-custom-properties-visibility][org-toggle-custom-properties-visibility]].  This might
     be useful for properties used by third-part tools or that you
     don't want to see temporarily.

**** New command [[doc::org-redisplay-inline-images][org-redisplay-inline-images]]

     This will redisplay all images.  It is bound to =C-c C-x C-M-v=.

**** New entities in =org-entities.el=

     There are these new entities:

     : ("tilde" "\\~{}" nil "&tilde;" "~" "~" "~")
     : ("slash" "/" nil "/" "/" "/" "/")
     : ("plus" "+" nil "+" "+" "+" "+")
     : ("under" "\\_" nil "_" "_" "_" "_")
     : ("equal" "=" nil "=" "=" "=" "=")
     : ("asciicirc" "\\textasciicircum{}" nil "^" "^" "^" "^")

**** New face =org-list-dt= for definition terms
**** New face =org-date-selected= for the selected calendar day
**** New face value for =org-document-title=

     The face is back to a normal height.

*** Org Columns

**** New speed command =:= to activate the column view
**** New special property =CLOCKSUM_T= to display today's clocked time

     You can use =CLOCKSUM_T= the same way you use =CLOCKSUM=.  It
     will display the time spent on tasks for today only.

**** Use the =:COLUMNS:= property in columnview dynamic blocks

     If the =:COLUMNS:= is set in a subtree, the columnview dynamic
     block will use its value as the column format.

**** Consider inline tasks when computing a sum

*** Org Dates and Time Stamps

**** Enhanced [[doc::org-sparse-tree][org-sparse-tree]]

     =C-c /= can now check for time ranges.

     When checking for dates with =C-c /= it is useful to change the
     type of dates that you are interested in.  You can now do this
     interactively with =c= after =C-c /= and/or by setting
     [[doc::org-sparse-tree-default-date-type][org-sparse-tree-default-date-type]] to the default value you want.

**** Support for hourly repeat cookies

     You can now use

     : SCHEDULED: <2012-08-20 lun. 08:00 +1h>

     if you want to add an hourly repeater to an entry.

**** =C-u C-u C-c .= inserts a time-stamp with no prompt

**** When (setq [[doc::org-read-date-prefer-future][org-read-date-prefer-future]] 'time), accept days in the prompt

     "8am Wed" and "Wed 8am" are now acceptable values when entering a
     date from the prompt.  If [[doc::org-read-date-prefer-future][org-read-date-prefer-future]] is set to
     =time=, this will produce the expected prompt indication.

**** New option [[doc::org-datetree-add-timestamp][org-datetree-add-timestamp]]

     When set to =non-nil=, datetree entries will also have a
     timestamp.  This is useful if you want to see these entries in a
     sparse tree with =C-c /=.

*** Org Capture

**** New command [[doc::org-capture-string][org-capture-string]]

     M-x [[doc::org-capture-string][org-capture-string]] RET will prompt for a string and a capture
     template.  The string will be used as an annotation for the
     template.  This is useful when capturing in batch mode as it lets
     you define the content of the template without being in Emacs.

**** New option [[doc::org-capture-templates-contexts][org-capture-templates-contexts]]

     Setting this option allows you to define specific context where
     capture templates should be available from.  For example, when
     set to this value

     #+BEGIN_SRC emacs-lisp
  (setq org-capture-templates-contexts
        '(("c" (in-mode . "message-mode"))))
#+END_SRC

     then the =c= capture template will only be available from
     =message-mode= buffers.  See the docstring and the manual for
     more details on how to use this.

**** New =%l= template to insert the literal link
**** New option [[doc::org-capture-bookmark][org-capture-bookmark]]

     Org used to automatically add a bookmark with capture a note.
     You can now turn this on by setting [[doc::org-capture-bookmark][org-capture-bookmark]] to
     =nil=.

**** Expand =%<num>= escape sequences into text entered for <num>'th =%^{PROMPT}= escape

     See the manual for more explanations.

**** More control over empty lines

     You can use =:empty-lines-before= and =:empty-lines-after= to
     control the insertion of empty lines.  Check the manual for more
     explanations.

**** New hook [[doc::org-capture-prepare-finalize-hook][org-capture-prepare-finalize-hook]]

     This new hook runs before the finalization process starts.

*** Org Export

**** New functions =orgtbl-to-table.el= and =orgtbl-to-unicode=

     =orgtbl-to-table.el= convert the table to a =table.el= table, and
     =orgtbl-to-unicode= will use =ascii-art-to-unicode.el= (when
     available) to print beautiful tables.

**** [[doc::org-table-export][org-table-export]] now a bit clever about the target format

     When you specify a file name like =table.csv=, [[doc::org-table-export][org-table-export]]
     will now suggest =orgtbl-to-csv= the default method for exporting
     the table.

**** New option [[doc::org-export-date-timestamp-format][org-export-date-timestamp-format]]

     The option allows to set a time string format for Org timestamps
     in the #+DATE option.

**** LaTeX: New options for exporting table rules :tstart, :hline and :tend

     See [[doc::org-export-latex-tables-hline][org-export-latex-tables-hline]] and [[doc::org-export-latex-tables-tend][org-export-latex-tables-tend]].

**** LaTeX: You can now set =:hfmt= from =#+ATTR_LaTeX=
**** Beamer: Add support and keybinding for the =exampleblock= environment

     Add support for these languages in [[doc::org-export-language-setup][org-export-language-setup]].
     More languages are always welcome.

**** Beamer: New option [[doc::org-beamer-inherited-properties][org-beamer-inherited-properties]]

     This option allows Beamer export to inherit some properties.
     Thanks to Carsten for implementing this.

**** ODT: Add support for ODT export in org-bbdb.el
**** ODT: Add support for indented tables (see [[https://orgmode.org/cgit.cgi/org-mode.git/commit/?id=e9fd33][this commit]] for details)
**** ODT: Improve the conversion from ODT to other formats
**** ASCII: Swap the level-1/level-2 characters to underline the headlines
**** Support for Chinese, simplified Chinese, Russian, Ukrainian and Japanese
**** HTML: New option [[doc::org-export-html-date-format-string][org-export-html-date-format-string]]

     Format string to format the date and time in HTML export.  Thanks
     to Sébastien Vauban for this patch.

*** Org Babel

**** New =:results drawer= parameter

=:results drawer= replaces =:results wrap=, which is deprecated but still
supported.

**** =:results org= now put results in a =#+BEGIN_SRC org= block

=:results org= used to put results in a =#+BEGIN_ORG= block but it now puts
results in a =#+BEGIN_SRC org= block, with comma-escaped lines.

=#+BEGIN_ORG= blocks are obsolete.

**** Exporting =#+BEGIN_SRC org= blocks exports the code

It used to exports the results of the code.

*** Miscellaneous

**** New menu entry for [[doc::org-refile][org-refile]]
**** Allow capturing to encrypted entries

If you capture to an encrypted entry, it will be decrypted before
inserting the template then re-encrypted after finalizing the capture.

**** Inactive timestamps are now handled in tables

Calc can do computation on active time-stamps like <2012-09-29 sat.>.
Inactive time-stamps in a table's cell are now internally deactivated so
that Calc formulas can operate on them.

**** [[doc::org-table-number-regexp][org-table-number-regexp]] can now accept comma as decimal mark
**** Org allows a new property =APPT_WARNTIME=

     You can set it with the =W= speedy key or set it manually.  When
     set, exporting to iCalendar and [[doc::org-agenda-to-appt][org-agenda-to-appt]] will use the
     value of this property as the number of minutes for the warning
     alarm.

**** New command [[doc::org-inc-effort][org-inc-effort]]

     This will increment the effort value.

     It is bound to =C-c C-x E= and to =E= as a speedy command.

**** Attach: Add support for creating symbolic links

     =org-attach-method= now supports a new method =lns=, allowing to
     attach symbolic links.

**** Archive: you can now archive to a datetree

**** New option [[doc::org-inlinetask-show-first-star][org-inlinetask-show-first-star]]

     =Non-nil= means display the first star of an inline task as
     additional marker.  When =nil=, the first star is not shown.

**** New option [[doc::org-latex-preview-ltxpng-directory][org-latex-preview-ltxpng-directory]]

     This lets you define the path for the =ltxpng/= directory.

**** You can now use imagemagick instead of dvipng to preview LaTeX fragments
**** You can now turn off [[doc::orgstruct++-mode][orgstruct++-mode]] safely
**** =C-u C-c C-c= on list items to add check boxes

     =C-u C-c C-c= will add an empty check box on a list item.

     When hit from the top of the list, it will add check boxes for
     all top level list items.

**** =org-list-ending-method= and =org-list-end-regexp= are now obsolete

     Fall back on using =org-list-end-re= only, which see.

**** org-feed.el now expands =%(sexp)= templates
**** New option [[doc::org-protocol-data-separator][org-protocol-data-separator]]

**** New option [[doc::org-ditaa-jar-option][org-ditaa-jar-option]] to specify the ditaa jar file

**** New possible value for [[doc::org-loop-over-headlines-in-active-region][org-loop-over-headlines-in-active-region]]

     When [[doc::org-loop-over-headlines-in-active-region][org-loop-over-headlines-in-active-region]] is set to
     =start-level=, the command will loop over the active region but
     will only act upon entries that are of the same level than the
     first headline in the region.

**** New option [[doc::org-habit-show-all-today][org-habit-show-all-today]]

     When set to =t=, show all (even unscheduled) habits on today's
     agenda.

** Important bug fixes

*** M-TAB on options keywords perform completion correctly again

    If you hit =M-TAB= on keywords like =#+TITLE=, Org will try to
    perform completion with meaningful values.

*** Add licenses to javascript embedded and external code snippets

    Embedded javascript code produced when exporting an Org file to
    HTML is now licensed under GPLv3 (or later), and the copyright is
    owned by the Free Software Foundation, Inc.

    The javascript code for embedding MathJax in the browser mentions
    the MathJax copyright and the Apache 2.0 license.

    The javascript code for embedding =org-injo.js= in the browser
    mentions the copyright of Sebastian Rose and the GPLv3 (or later)
    license.

    =org-export-html-scripts= is now a variable, so that you can adapt
    the code and the license to your needs.

    See https://www.gnu.org/philosophy/javascript-trap.html for
    explanations on why these changes were necessary.

* Version 7.8.11

** Incompatible changes

*** Emacs 21 support has been dropped

    Do not use Org mode 7.xx with Emacs 21, use [[https://orgmode.org/org-6.36c.zip][version 6.36c]] instead.

*** XEmacs support requires the XEmacs development version

    To use Org mode 7.xx with XEmacs, you need to run the developer
    version of XEmacs.  We were about to drop XEmacs support entirely,
    but Michael Sperber stepped in and made changes to XEmacs that
    made it easier to keep the support.  Thanks to Michael for this
    last-minute save.

*** New keys for TODO sparse trees

    The key =C-c C-v= is now reserved for Org Babel action.  TODO
    sparse trees can still be made with =C-c / t= (all not-done
    states) and =C-c / T= (specific states).

*** The Agenda =org-agenda-ndays= is now obsolete

    The variable =org-agenda-ndays= is obsolete - please use
    =org-agenda-span= instead.

    Thanks to Julien Danjou for this.

*** Changes to the intended use of =org-export-latex-classes=

    So far this variable has been used to specify the complete header
    of the LaTeX document, including all the =\usepackage= calls
    necessary for the document.  This setup makes it difficult to
    maintain the list of packages that Org itself would like to call,
    for example for the special symbol support it needs.

    First of all, you can *opt out of this change* in the following
    way: You can say: /I want to have full control over headers, and I
    will take responsibility to include the packages Org needs/.  If
    that is what you want, add this to your configuration and skip the
    rest of this section (except maybe for the description of the
    =[EXTRA]= place holder):

    #+begin_src emacs-lisp
   (setq org-export-latex-default-packages-alist nil
         org-export-latex-packages-alist nil)
    #+end_src

    /Continue to read here if you want to go along with the modified
    setup./

    There are now two variables that should be used to list the LaTeX
    packages that need to be included in all classes.  The header
    definition in =org-export-latex-classes= should then not contain
    the corresponding =\usepackage= calls (see below).

    The two new variables are:

    1. =org-export-latex-default-packages-alist= :: This is the
         variable where Org-mode itself puts the packages it needs.
         Normally you should not change this variable.  The only
         reason to change it anyway is when one of these packages
         causes a conflict with another package you want to use.  Then
         you can remove that packages and hope that you are not using
         Org-mode functionality that needs it.

    2. =org-export-latex-packages-alist= :: This is the variable where
         you can put the packages that you'd like to use across all
         classes.

    The sequence how these customizations will show up in the LaTeX
    document are:

    1. Header from =org-export-latex-classes=
    2. =org-export-latex-default-packages-alist=
    3. =org-export-latex-packages-alist=
    4. Buffer-specific things set with =#+LaTeX_HEADER:=

    If you want more control about which segment is placed where, or
    if you want, for a specific class, have full control over the
    header and exclude some of the automatic building blocks, you can
    put the following macro-like place holders into the header:

    #+begin_example
    [DEFAULT-PACKAGES]      \usepackage statements for default packages
    [NO-DEFAULT-PACKAGES]   do not include any of the default packages
    [PACKAGES]              \usepackage statements for packages
    [NO-PACKAGES]           do not include the packages
    [EXTRA]                 the stuff from #+LaTeX_HEADER
    [NO-EXTRA]              do not include #+LaTeX_HEADER stuff
    #+end_example

    If you have currently customized =org-export-latex-classes=, you
    should revise that customization and remove any package calls that
    are covered by =org-export-latex-default-packages-alist=.  This
    applies to the following packages:

    - inputenc
    - fontenc
    - fixltx2e
    - graphicx
    - longtable
    - float
    - wrapfig
    - soul
    - t1enc
    - textcomp
    - marvosym
    - wasysym
    - latexsym
    - amssymb
    - hyperref

    If one of these packages creates a conflict with another package
    you are using, you can remove it from
    =org-export-latex-default-packages-alist=.  But then you risk that
    some of the advertised export features of Org will not work
    properly.

    You can also consider moving packages that you use in all classes
    to =org-export-latex-packages-alist=.  If necessary, put the place
    holders so that the packages get loaded in the right sequence.  As
    said above, for backward compatibility, if you omit the place
    holders, all the variables will dump their content at the end of
    the header.

*** The constant =org-html-entities= is obsolete

    Its content is now part of the new constant =org-entities=, which
    is defined in the file org-entities.el.  =org-html-entities= was
    an internal variable, but it is possible that some users did write
    code using it.

*** =org-bbdb-anniversary-format-alist= has changed

    Please check the docstring and update your settings accordingly.

*** Deleted =org-mode-p=

    This function has been deleted: please update your code.

** Important new features

*** New Org to ODT exporter

    Jambunathan's Org to ODT exporter is now part of Org.

    To use it, it `C-c C-e o' in an Org file.  See the documentation
    for more information on how to customize it.

*** org-capture.el is now the default capture system

    This replaces the earlier system org-remember.  The manual only
    describes org-capture, but for people who prefer to continue to
    use org-remember, we keep a static copy of the former manual
    section [[https://orgmode.org/org-remember.pdf][chapter about remember]].

    The new system has a technically cleaner implementation and more
    possibilities for capturing different types of data.  See
    [[msg:C46F10DC-DE51-43D4-AFFE-F71E440D1E1F@gmail.com][Carsten's announcement]] for more details.

    To switch over to the new system:

    1. Run

     : M-x org-capture-import-remember-templates RET

       to get a translated version of your remember templates into the
       new variable =org-capture-templates=.  This will "mostly" work,
       but maybe not for all cases.  At least it will give you a good
       place to modify your templates.  After running this command,
       enter the customize buffer for this variable with

     : M-x customize-variable RET org-capture-templates RET

       and convince yourself that everything is OK.  Then save the
       customization.

    2. Bind the command =org-capture= to a key, similar to what you did
       with org-remember:

     : (define-key global-map "\C-cc" 'org-capture)

       If your fingers prefer =C-c r=, you can also use this key once
       you have decided to move over completely to the new
       implementation.  During a test time, there is nothing wrong
       with using both system in parallel.

** New libraries

*** New Org libraries
**** org-eshell.el (Konrad Hinsen)

     Implement links to eshell buffers.

**** org-special-blocks (Carsten Dominik)

     This package generalizes the #+begin_foo and #+end_foo tokens.

     To use, put the following in your init file:

     #+BEGIN_EXAMPLE
(require 'org-special-blocks)
#+END_EXAMPLE

     The tokens #+begin_center, #+begin_verse, etc. existed
     previously.  This package generalizes them (at least for the
     LaTeX and html exporters).  When a #+begin_foo token is
     encountered by the LaTeX exporter, it is expanded
     into \begin{foo}.  The text inside the environment is not
     protected, as text inside environments generally is.
     When #+begin_foo is encountered by the html exporter, a div with
     class foo is inserted into the HTML file.  It is up to the user
     to add this class to his or her stylesheet if this div is to mean
     anything.

**** org-taskjuggler.el (Christian Egli)

     Christian Egli's /org-taskjuggler.el/ module is now part of Org.
     He also wrote a [[https://orgmode.org/worg/org-tutorials/org-taskjuggler.php][tutorial]] for it.

**** org-ctags.el (Paul Sexton)

     Targets like =<<my target>>= can now be found by Emacs' etag
     functionality, and Org-mode links can be used to link to
     etags, also in non-Org-mode files.  For details, see the file
     /org-ctags.el/.

     This feature uses a new hook =org-open-link-functions= which will
     call function to do something special with text links.

     Thanks to Paul Sexton for this contribution.

**** org-docview.el (Jan Böcker)

     This new module allows links to various file types using docview, where
     Emacs displays images of document pages.  Docview link types can point
     to a specific page in a document, for example to page 131 of the
     Org-mode manual:

     : [[docview:~/.elisp/org/doc/org.pdf::131][Org-Mode Manual]]

     Thanks to Jan Böcker for this contribution.

*** New Babel libraries

- ob-picolisp.el (Thorsten Jolitz)
- ob-fortran.el (Sergey Litvinov)
- ob-shen.el (Eric Schulte)
- ob-maxima.el (Eric S Fraga)
- ob-java.el (Eric Schulte)
- ob-lilypond.el (Martyn Jago)
- ob-awk.el (Eric Schulte)

** Other new features and various enhancements

*** Hyperlinks

**** Org-Bibtex -- major improvements

     Provides support for managing bibtex bibliographical references
     data in headline properties.  Each headline corresponds to a
     single reference and the relevant bibliographic meta-data is
     stored in headline properties, leaving the body of the headline
     free to hold notes and comments.  Org-bibtex is aware of all
     standard bibtex reference types and fields.

     The key new functions are

     - org-bibtex-check :: queries the user to flesh out all required
          (and with prefix argument optional) bibtex fields available
          for the specific reference =type= of the current headline.

     - org-bibtex-create :: Create a new entry at the given level,
          using org-bibtex-check to flesh out the relevant fields.

     - org-bibtex-yank :: Yank a bibtex entry on the kill ring as a
          formatted Org-mode headline into the current buffer

     - org-bibtex-export-to-kill-ring :: Export the current headline
          to the kill ring as a formatted bibtex entry.

**** org-gnus.el now allows link creation from messages

     You can now create links from messages.  This is particularly
     useful when the user wants to stored messages that he sends, for
     later check.  Thanks to Ulf Stegemann for the patch.

**** Modified link escaping

     David Maus worked on `org-link-escape'.  See [[msg:87k4gysacq.wl%dmaus@ictsoc.de][his message]]:

     : Percent escaping is used in Org mode to escape certain characters
     : in links that would either break the parser (e.g. square brackets
     : in link target or description) or are not allowed to appear in
     : a particular link type (e.g. non-ascii characters in a http:
     : link).
     :
     : With this change in place Org will apply percent escaping and
     : unescaping more consistently especially for non-ascii characters.
     : Additionally some of the outstanding bugs or glitches concerning
     : percent escaped links are solved.

     Thanks a lot to David for this work.

**** Make =org-store-link= point to directory in a dired buffer

     When, in a dired buffer, the cursor is not in a line listing a
     file, `org-store-link' will store a link to the directory.

     Patch by Stephen Eglen.

**** Allow regexps in =org-file-apps= to capture link parameters

     The way extension regexps in =org-file-apps= are handled has
     changed.  Instead of matching against the file name, the regexps
     are now matched against the whole link, and you can use grouping
     to extract link parameters which you can then use in a command
     string to be executed.

     For example, to allow linking to PDF files using the syntax
     =file:/doc.pdf::<page number>=, you can add the following entry
     to org-file-apps:

     #+begin_example
     Extension: \.pdf::\([0-9]+\)\'
     Command:   evince "%s" -p %1
     #+end_example

     Thanks to Jan Böcker for a patch to this effect.

*** Dates and time

**** Allow relative time when scheduling/adding a deadline

     You can now use relative duration strings like "-2d" or "++3w"
     when calling =org-schedule= or =org-deadline=: it will schedule
     (or set the deadline for) the item respectively two days before
     today and three weeks after the current timestamp, if any.

     You can use this programmatically: =(org-schedule nil "+2d")=
     will work on the current entry.

     You can also use this while (bulk-)rescheduling and
     (bulk-)resetting the deadline of (several) items from the agenda.

     Thanks to Memnon Anon for a heads up about this!

**** American-style dates are now understood by =org-read-date=

     So when you are prompted for a date, you can now answer like this

     #+begin_example
     2/5/3         --> 2003-02-05
     2/5           --> <CURRENT-YEAR>-02-05
     #+end_example

*** Agenda

**** =org-agenda-custom-commands= has a default value

     This option used to be `nil' by default.  This now has a default
     value, displaying an agenda and all TODOs.  See the docstring for
     details.  Thanks to Carsten for this.

**** Improved filtering through =org-agenda-to-appt=

     The new function allows the user to refine the scope of entries
     to pass to =org-agenda-get-day-entries= and allows to filter out
     entries using a function.

     Thanks to Peter Münster for raising a related issue and to
     Tassilo Horn for this idea.  Also thanks to Peter Münster for
     [[git:68ffb7a7][fixing a small bug]] in the final implementation.

**** Allow ap/pm times in agenda time grid

     Times in the agenda can now be displayed in am/pm format.  See
     the new variable =org-agenda-timegrid-use-ampm=.  Thanks to
     C. A. Webber for a patch to this effect.

**** Agenda: Added a bulk "scattering" command

     =B S= in the agenda buffer will cause tasks to be rescheduled a
     random number of days into the future, with 7 as the default.
     This is useful if you've got a ton of tasks scheduled for today,
     you realize you'll never deal with them all, and you just want
     them to be distributed across the next N days.  When called with
     a prefix arg, rescheduling will avoid weekend days.

     Thanks to John Wiegley for this.

*** Exporting

**** Simplification of org-export-html-preamble/postamble

     When set to `t', export the preamble/postamble as usual, honoring
     the =org-export-email/author/creator-info= variables.

     When set to a formatting string, insert this string.  See the
     docstring of these variable for details about available
     %-sequences.

     You can set =:html-preamble= in publishing project in the same
     way: `t' means to honor =:email/creator/author-info=, and a
     formatting string will insert a string.

**** New exporters to Latin-1 and UTF-8

     While Ulf Stegemann was going through the entities list to
     improve the LaTeX export, he had the great idea to provide
     representations for many of the entities in Latin-1, and for all
     of them in UTF-8.  This means that we can now export files rich
     in special symbols to Latin-1 and to UTF-8 files.  These new
     exporters can be reached with the commands =C-c C-e n= and =C-c
     C-e u=, respectively.

     When there is no representation for a given symbol in the
     targeted coding system, you can choose to keep the TeX-macro-like
     representation, or to get an "explanatory" representation.  For
     example, =\simeq= could be represented as "[approx. equal to]".
     Please use the variable =org-entities-ascii-explanatory= to state
     your preference.

**** HTML export: Add class to outline containers using property

     The =HTML_CONTAINER_CLASS= property can now be used to add a
     class name to the outline container of a node in HTML export.

**** Throw an error when creating an image from a LaTeX snippet fails

     This behavior can be configured with the new option variable
     =org-format-latex-signal-error=.

**** Support for creating BEAMER presentations from Org-mode documents

     Org-mode documents or subtrees can now be converted directly in
     to BEAMER presentation.  Turning a tree into a simple
     presentations is straight forward, and there is also quite some
     support to make richer presentations as well.  See the [[https://orgmode.org/manual/Beamer-class-export.html#Beamer-class-export][BEAMER
     section]] in the manual for more details.

     Thanks to everyone who has contributed to the discussion about
     BEAMER support and how it should work.  This was a great example
     for how this community can achieve a much better result than any
     individual could.

*** Refiling

**** Refile targets can now be cached

     You can turn on caching of refile targets by setting the variable
     =org-refile-use-cache=.  This should speed up refiling if you
     have many eligible targets in many files.  If you need to update
     the cache because Org misses a newly created entry or still
     offers a deleted one, press =C-0 C-c C-w=.

**** New logging support for refiling

     Whenever you refile an item, a time stamp and even a note can be
     added to this entry.  For details, see the new option
     =org-log-refile=.

     Thanks to Charles Cave for this idea.

*** Completion

**** In-buffer completion is now done using John Wiegley's pcomplete.el

     Thanks to John Wiegley for much of this code.

*** Tables

**** New command =org-table-transpose-table-at-point=

     See the docstring.  This hack from Juan Pechiar is now part of
     Org's core.  Thanks to Juan!

**** Display field's coordinates when editing it with =C-c `=

     When editing a field with =C-c `=, the field's coordinate will
     the displayed in the buffer.

     Thanks to Michael Brand for a patch to this effect.

**** Spreadsheet computation of durations and time values

     If you want to compute time values use the =T= flag, either in
     Calc formulas or Elisp formulas:

     | Task 1 | Task 2 |   Total |
     |--------+--------+---------|
     |  35:00 |  35:00 | 1:10:00 |
     #+TBLFM: @2$3=$1+$2;T

     Values must be of the form =[HH:]MM:SS=, where hours are
     optional.

     Thanks to Martin Halder, Eric Schulte and Carsten for code and
     feedback on this.

**** Implement formulas applying to field ranges

     Carsten implemented this field-ranges formulas.

     : A frequently requested feature for tables has been to be able to define
     : row formulas in a way similar to column formulas.  The patch below allows
     : things like
     :
     : @3=
     : @2$2..@5$7=
     : @I$2..@II$4=
     :
     : as the left hand side for table formulas in order to write a formula that
     : is valid for an entire column or for a rectangular section in a
     : table.

     Thanks a lot to Carsten for this.

**** Sending radio tables from org buffers is now allowed

     Org radio tables can no also be sent inside Org buffers.  Also,
     there is a new hook which get called after a table has been sent.

     Thanks to Seweryn Kokot.

*** Lists

**** Improved handling of lists

     Nicolas Goaziou extended and improved the way Org handles lists.

     1. Indentation of text determines again end of items in
        lists. So, some text less indented than the previous item
        doesn't close the whole list anymore, only all items more
        indented than it.

     2. Alphabetical bullets are implemented, through the use of the
        variable `org-alphabetical-lists'. This also adds alphabetical
        counters like [@c] or [@W].

     3. Lists can now safely contain drawers, inline tasks, or various
        blocks, themselves containing lists. Two variables are
        controlling this: `org-list-forbidden-blocks', and
        `org-list-export-context'.

     4. Improve `newline-and-indent' (C-j): used in an item, it will
        keep text from moving at column 0. This allows to split text
        and make paragraphs and still not break the list.

     5. Improve `org-toggle-item' (C-c -): used on a region with
        standard text, it will change the region into one item. With a
        prefix argument, it will fallback to the previous behavior and
        make every line in region an item. It permits to easily
        integrate paragraphs inside a list.

     6. `fill-paragraph' (M-q) now understands lists. It can freely be
        used inside items, or on text just after a list, even with no
        blank line around, without breaking list structure.

     Thanks a lot to Nicolas for all this!

*** Inline display of linked images

    Images can now be displayed inline.  The key C-c C-x C-v does
    toggle the display of such images.  Note that only image links
    that have no description part will be inlined.

*** Implement offsets for ordered lists

    If you want to start an ordered plain list with a number different
    from 1, you can now do it like this:

    : 1. [@start:12] will star a lit a number 12

*** Babel: code block body expansion for table and preview

    In org-babel, code is "expanded" prior to evaluation. I.e. the
    code that is actually evaluated comprises the code block contents,
    augmented with the extra code which assigns the referenced data to
    variables. It is now possible to preview expanded contents, and
    also to expand code during tangling. This expansion takes
    into account all header arguments, and variables.

    A new keybinding `C-c M-b p' bound to `org-babel-expand-src-block'
    can be used from inside of a source code block to preview its
    expanded contents (which can be very useful for debugging).
    tangling

    The expanded body can now be tangled, this includes variable
    values which may be the results of other source-code blocks, or
    stored in headline properties or tables. One possible use for this
    is to allow those using org-babel for their emacs initialization
    to store values (e.g. usernames, passwords, etc...) in headline
    properties or in tables.

    Org-babel now supports three new header arguments, and new default
    behavior for handling horizontal lines in tables (hlines), column
    names, and rownames across all languages.

*** Editing Convenience and Appearance

**** New command =org-copy-visible= (=C-c C-x v=)

     This command will copy the visible text in the region into the
     kill ring.  Thanks to Florian Beck for this function and to
     Carsten for adding it to org.el and documenting it!

**** Make it possible to protect hidden subtrees from being killed by =C-k=

     See the new variable =org-ctrl-k-protect-subtree=.  This was a
     request by Scott Otterson.

**** Implement pretty display of entities, sub-, and superscripts.

     The command =C-c C-x \= toggles the display of Org's special
     entities like =\alpha= as pretty unicode characters.  Also, sub
     and superscripts are displayed in a pretty way (raised/lower
     display, in a smaller font).  If you want to exclude sub- and
     superscripts, see the variable
     =org-pretty-entities-include-sub-superscripts=.

     Thanks to Eric Schulte and Ulf Stegeman for making this possible.

**** New faces for title, date, author and email address lines

     The keywords in these lines are now dimmed out, and the title is
     displayed in a larger font, and a special font is also used for
     author, date, and email information.  This is implemented by the
     following new faces:

     =org-document-title=
     =org-document-info=
     =org-document-info-keyword=

     In addition, the variable =org-hidden-keywords= can be used to
     make the corresponding keywords disappear.

     Thanks to Dan Davison for this feature.

**** Simpler way to specify faces for tags and todo keywords

     The variables =org-todo-keyword-faces=, =org-tag-faces=, and
     =org-priority-faces= now accept simple color names as
     specifications.  The colors will be used as either foreground or
     background color for the corresponding keyword.  See also the
     variable =org-faces-easy-properties=, which governs which face
     property is affected by this setting.

     This is really a great simplification for setting keyword faces.
     The change is based on an idea and patch by Ryan Thompson.

**** <N> in tables now means fixed width, not maximum width

     Requested by Michael Brand.

**** Better level cycling function

     =TAB= in an empty headline cycles the level of that headline
     through likely states.  Ryan Thompson implemented an improved
     version of this function, which does not depend upon when exactly
     this command is used.  Thanks to Ryan for this improvement.

**** Adaptive filling

     For paragraph text, =org-adaptive-fill-function= did not handle
     the base case of regular text which needed to be filled.  This is
     now fixed.  Among other things, it allows email-style ">"
     comments to be filled correctly.

     Thanks to Dan Hackney for this patch.

**** `org-reveal' (=C-c C-r=) also decrypts encrypted entries (org-crypt.el)

     Thanks to Richard Riley for triggering this change.

**** Better automatic letter selection for TODO keywords

     When all first letters of keywords have been used, Org now
     assigns more meaningful characters based on the keywords.

     Thanks to Mikael Fornius for this patch.

*** Clocking

**** Clock: Allow synchronous update of timestamps in CLOCK log

     Using =S-M-<up/down>= on CLOCK log timestamps will
     increase/decrease the two timestamps on this line so that
     duration will keep the same.  Note that duration can still be
     slightly modified in case a timestamp needs some rounding.

     Thanks to Rainer Stengele for this idea.

**** Localized clock tables

     Clock tables now support a new =:lang= parameter, allowing
     the user to customize the localization of the table headers.  See
     the variable =org-clock-clocktable-language-setup= which controls
     available translated strings.

**** Show clock overruns in mode line

     When clocking an item with a planned effort, overrunning the
     planned time is now made visible in the mode line, for example
     using the new face =org-mode-line-clock-overrun=, or by adding an
     extra string given by =org-task-overrun-text=.

     Thanks to Richard Riley for a patch to this effect.

**** Clock reports can now include the running, incomplete clock

     If you have a clock running, and the entry being clocked falls
     into the scope when creating a clock table, the time so far spent
     can be added to the total.  This behavior depends on the setting
     of =org-clock-report-include-clocking-task=.  The default is
     =nil=.

     Thanks to Bernt Hansen for this useful addition.

*** Misc

**** Improvements with inline tasks and indentation

     There is now a configurable way on how to export inline tasks.
     See the new variable =org-inlinetask-export-templates=.

     Thanks to Nicolas Goaziou for coding these changes.

**** A property value of =nil= now means to unset a property

     This can be useful in particular with property inheritance, if
     some upper level has the property, and some grandchild of it
     would like to have the default settings (i.e. not overruled by a
     property) back.

     Thanks to Robert Goldman and Bernt Hansen for suggesting this
     change.

**** New helper functions in org-table.el

     There are new functions to access and write to a specific table field.
     This is for hackers, and maybe for the org-babel people.

     #+begin_example
     org-table-get
     org-table-put
     org-table-current-line
     org-table-goto-line
     #+end_example

**** Archiving: Allow to reverse order in target node

     The new option =org-archive-reversed-order= allows to have
     archived entries inserted in a last-on-top fashion in the target
     node.

     This was requested by Tom.

**** Org-reveal: Double prefix arg shows the entire subtree of the parent

     This can help to get out of an inconsistent state produced for
     example by viewing from the agenda.

     This was a request by Matt Lundin.
