\f
* Installation Changes in Emacs 28.1

** Cairo graphics library is now used by default if found.
'--with-cairo' is now the default, if the appropriate development files
are found by 'configure'.  Note that building with Cairo means using
Pango instead of libXFT for font support.  Since Pango 1.44 has
removed support for bitmapped fonts, this may require you to adjust
your font settings.

Note also that 'FontBackend' settings in ".Xdefaults" or
".Xresources", or 'font-backend' frame parameter settings in your init
files, may need to be adjusted, as 'xft' is no longer a valid backend
when using Cairo.  Use 'ftcrhb' if your Emacs was built with HarfBuzz
text shaping support, and 'ftcr' otherwise.  You can determine this by
checking 'system-configuration-features'.  The 'ftcr' backend will
still be available when HarfBuzz is supported, but will not be used by
default.  We strongly recommend building with HarBuzz support.  'x' is
still a valid backend.

---
** 'configure' now warns about building with libXft support.
libXft is unmaintained, and causes a number of problems with modern
fonts including but not limited to crashes; support for it may be
removed in a future version of Emacs.  Please consider using
Cairo + HarfBuzz instead.

---
** 'configure' now warns about not using HarfBuzz if using Cairo.
We want to encourage people to use the most modern font features
available, and this is the Cairo graphics library + HarfBuzz for font
shaping, so 'configure' now recommends that combination.

---
** The ftx font backend driver has been removed.
It was declared obsolete in Emacs 27.1.

---
** Emacs no longer supports old OpenBSD systems.
OpenBSD 5.3 and older releases are no longer supported, as they lack
proper pty support that Emacs needs.

\f
* Startup Changes in Emacs 28.1

** Emacs can support 24-bit color TTY without terminfo database.
If your text-mode terminal supports 24-bit true color, but your system
lacks the terminfo database, you can instruct Emacs to support 24-bit
true color by setting 'COLORTERM=truecolor' in the environment.  This is
useful on systems such as FreeBSD which ships only with "etc/termcap".

\f
* Changes in Emacs 28.1

** Support for '(box . SIZE)' 'cursor-type'.
By default, 'box' cursor always has a filled box shape.  But if you
specify 'cursor-type' to be '(box . SIZE)', the cursor becomes a hollow
box if the point is on an image larger than 'SIZE' pixels in any
dimension.

---
*** Improved language transliteration in Malayalam input methods.
Added a new Mozhi scheme.  The inapplicable ITRANS scheme is now
deprecated.  Errors in the Inscript method were corrected.

\f
* Editing Changes in Emacs 28.1

+++
** New command 'undo-redo'.
It undoes previous undo commands, but doesn't record itself as an
undoable command.

+++
** 'read-number' now has its own history variable.
Additionally, the function now accepts a HIST argument which can be
used to specify a custom history variable.

+++
** Input history for 'goto-line' is now local to every buffer.
Each buffer will keep a separate history of line numbers used with
'goto-line'.  This should help making faster the process of finding
line numbers that were previously jumped to.

+++
** When 'suggest-key-bindings' is non-nil, the completion list of 'M-x'
shows equivalent key bindings for all commands that have them.

---
** Movement commands in 'gomoku-mode' are fixed.
'gomoku-move-sw' and 'gomoku-move-ne' now work correctly, and
horizontal movements now stop at the edge of the board.

** Autosaving via 'auto-save-visited-mode' can now be inhibited by
setting the variable 'auto-save-visited-mode' buffer-locally to nil.

\f
* Changes in Specialized Modes and Packages in Emacs 28.1

** Windows

*** The key prefix 'C-x 4 1' displays next command buffer in the same window.
It's bound to the command 'same-window-prefix' that requests the buffer
of the next command to be displayed in the same window.

*** The key prefix 'C-x 4 4' displays next command buffer in a new window.
It's bound to the command 'other-window-prefix' that requests the buffer
of the next command to be displayed in a new window.

** Frames

*** The key prefix 'C-x 5 5' displays next command buffer in a new frame.
It's bound to the command 'other-frame-prefix' that requests the buffer
of the next command to be displayed in a new frame.

** Tab Bars

*** The key prefix 'C-x t t' displays next command buffer in a new tab.
It's bound to the command 'other-tab-prefix' that requests the buffer
of the next command to be displayed in a new tab.

*** The tab bar is frame-local when 'tab-bar-show' is a number.
Show/hide the tab bar independently for each frame, according to the
value of 'tab-bar-show'.

** New bindings in occur-mode, 'next-error-no-select' bound to 'n' and
'previous-error-no-select' bound to 'p'.

** EIEIO

+++
*** The macro 'oref-default' can now be used with 'setf'.
It is now defined as a generalized variable that can be used with
'setf' to modify the value stored in a given class slot.

** New minor mode 'cl-font-lock-built-in-mode' for `lisp-mode'.
The mode provides refined highlighting of built-in functions, types,
and variables.

** Archive mode

*** Can now modify members of 'ar' archives.

*** Display of summaries unified between backends.

*** New user option 'archive-hidden-columns' and command
'archive-hideshow-column'.  These let you control which columns are
displayed and which are kept hidden.

** Emacs Lisp mode

*** The mode-line now indicates whether we're using lexical or dynamic scoping.

*** A space between an open paren and a symbol changes the indentation rule.
The presence of a space between an open paren and a symbol now is
taken as a statement by the programmer that this should be indented
as a data list rather than as a piece of code.

** Dired

*** New user option 'dired-mark-region' affects all Dired commands
that mark files.  When non-nil and the region is active in Transient
Mark mode, then Dired commands operate only on files in the active
region.  The values 'file' and 'line' of this user option define the
details of marking the file at the end of the region.

*** State changing VC operations are supported in Dired on files and
directories with the help of new command 'dired-vc-next-action'.

** Change Logs and VC

*** More VC commands can be used from non-file buffers.
The relevant commands are those that don't change the VC state.
The non-file buffers which can use VC commands are those that have
their 'default-directory' under VC.

*** New command 'vc-dir-root' uses the root directory without asking.

*** New commands 'vc-dir-mark-registered-files' (bound to '* r') and
'vc-dir-mark-unregistered-files'.

*** Support for bookmark.el.
Bookmark locations can refer to VC directory buffers.

** Gnus

+++
*** The name of dependent Gnus sessions has changed from "slave" to "child".
The names of the commands 'gnus-slave', 'gnus-slave-no-server' and
'gnus-slave-unplugged' have changed to 'gnus-child',
'gnus-child-no-server' and 'gnus-child-unplugged' respectively.

+++
*** The 'W Q' summary mode command now takes a numerical prefix to
allow adjusting the fill width.

---
*** Change to default value of 'message-draft-headers' user option.
The 'Date' symbol has been removed from the default value, meaning that
draft or delayed messages will get a date reflecting when the message
was sent.  To restore the original behavior of dating a message
from when it is first saved or delayed, add the symbol 'Date' back to
this user option.

** Help

+++
*** New command 'describe-keymap' describes keybindings in a keymap.

---
*** The command 'view-lossage' can now be invoked from the menu bar.
The menu-bar Help menu now has a "Show Recent Inputs" item under the
"Describe" sub-menu.

---
** The old non-SMIE indentation of 'sh-mode' has been removed.

---
** The sb-image.el library is now marked obsolete.
This file was a compatibility kludge which is no longer needed.

---
** Lisp mode now uses 'common-lisp-indent-function'.
To revert to the previous behaviour,
'(setq lisp-indent-function 'lisp-indent-function)' from 'lisp-mode-hook'.

** Edebug

+++
*** Edebug specification lists can use the new keyword '&error', which
unconditionally aborts the current edebug instrumentation with the
supplied error message.

+++
** ElDoc

*** New hook 'eldoc-documentation-functions'.
This hook is intended to be used for registering doc string functions.
These functions don't need to produce the doc string right away, they
may arrange for it to be produced asynchronously.  The results of all
doc string functions are accessible to the user through the existing
variable 'eldoc-documentation-strategy'.

*** New user option 'eldoc-documentation-strategy'.
The built-in choices available for this user option let users compose
the results of 'eldoc-documentation-functions' in various ways, even
if some of those functions are sychronous and some asynchchronous.
The user option replaces 'eldoc-documentation-function', which is now
obsolete.

*** 'eldoc-echo-area-use-multiline-p' is now handled by ElDoc.
The user option 'eldoc-echo-area-use-multiline-p' is now handled
by the ElDoc library itself.  Functions in
'eldoc-documentation-functions' don't need to worry about consulting
it when producing a doc string.

** Eshell

---
*** Environment variable 'INSIDE_EMACS' is now copied to subprocesses.
Its value equals the result of evaluating '(format "%s,eshell" emacs-version)'.

---
*** Eshell no longer re-initializes its keymap every call.
This allows users to use (define-key eshell-mode-map ...) as usual.
Some modules have their own minor mode now to account for these
changes.

** EUDC

+++
*** New macOS Contacts backend.
This backend works on newer versions of macOS and is generally
preferred over the eudcb-mab.el backend.

** Tramp

+++
*** New connection method "media", which allows accessing media devices
like cell phones, tablets or cameras.

+++
*** New command 'tramp-crypt-add-directory'.
This command marks a remote directory to contain only encrypted files.
See the "(tramp) Keeping files encrypted" node of the Tramp manual for
details.  This feature is experimental.

** Tempo

---
*** 'tempo-define-template' can now re-assign templates to tags.
Previously, assigning a new template to an already defined tag had no
effect.

** map.el

*** Pcase 'map' pattern added keyword symbols abbreviation.
A pattern like '(map :sym)' binds the map's value for ':sym' to 'sym',
equivalent to '(map (:sym sym))'.

** Package

+++
*** New functions to filter the package list.
The filter command key bindings are as follows:

key             binding
---             -------
/ a             package-menu-filter-by-archive
/ k             package-menu-filter-by-keyword
/ n             package-menu-filter-by-name
/ s             package-menu-filter-by-status
/ v             package-menu-filter-by-version
/ m             package-menu-filter-marked
/ /             package-menu-filter-clear

---
+++ Column widths in 'list-packages' display can now be customized.
See the new user options 'package-name-column-width',
'package-version-column-width', 'package-status-column-width', and
'package-archive-column-width'.

** gdb-mi

+++
*** gdb-mi can now store and restore window configurations.
Use 'gdb-save-window-configuration' to save window configuration to a
file and 'gdb-load-window-configuration' to load from a file.  These
commands can also be accessed through the menu bar under 'Gud --
GDB-Windows'.  'gdb-default-window-configuration-file', when non-nil,
is loaded when GDB starts up.

+++
*** gdb-mi can now restore window configuration after quit.
Set 'gdb-restore-window-configuration-after-quit' to non-nil and Emacs
will remember the window configuration before GDB started and restore
it after GDB quits.  A toggle button is also provided under 'Gud --
GDB-Windows'.

+++
*** gdb-mi now has a better logic for displaying source buffers.
Now GDB only uses one source window to display source file by default.
Customize 'gdb-max-source-window-count' to use more than one window.
Control source file display by 'gdb-display-source-buffer-action'.

** Gravatar

---
*** New user option 'gravatar-service' for host to query for gravatars.
Defaults to 'libravatar', with 'unicornify' and 'gravatar' as options.

** Compilation mode

*** Regexp matching of messages is now case-sensitive by default.
The variable 'compilation-error-case-fold-search' can be set for
case-insensitive matching of messages when the old behaviour is
required, but the recommended solution is to use a correctly matching
regexp instead.

** Hi Lock mode

---
*** Matching in 'hi-lock-mode' is case-sensitive when regexp contains
upper case characters and 'search-upper-case' is non-nil.
'highlight-phrase' also uses 'search-whitespace-regexp'
to substitute spaces in regexp search.

---
*** The default value of 'hi-lock-highlight-range' was enlarged.
The new default value is 2000000 (2 megabytes).

** Texinfo

---
*** New user option 'texinfo-texi2dvi-options'.
This is used when invoking 'texi2dvi' from 'texinfo-tex-buffer'.

** Rmail

---
*** New user option 'rmail-re-abbrevs'.
Its default value matches localized abbreviations of the "reply"
prefix on the Subject line in various languages.

** Apropos

*** New commands 'apropos-next-symbol' and 'apropos-previous-symbol'.
These new navigation commands are bound to 'n' and 'p' in
'apropos-mode'.

** CC Mode

*** Added support for Doxygen documentation style.
'doxygen' is now a valid 'c-doc-comment-style' which recognises all
comment styles supported by Doxygen (namely '///', '//!', '/** … */'
and '/*! … */'.  'gtkdoc' remains the default for C and C++ modes; to
use 'doxygen' by default one might evaluate:

    (setq-default c-doc-comment-style
                  '((java-mode . javadoc)
                    (pike-mode . autodoc)
                    (c-mode    . doxygen)
                    (c++-mode  . doxygen)))

or use it in a custom 'c-style'.

*** Added support to line up '?' and ':' of a ternary operator.
The new 'c-lineup-ternary-bodies' function can be used as a lineup
function to align question mark and colon which are part of a ternary
operator ('?:').  For example:

    return arg % 2 == 0 ? arg / 2
                        : (3 * arg + 1);

To enable, add it to appropriate entries in 'c-offsets-alist', e.g.:

    (c-set-offset 'arglist-cont '(c-lineup-ternary-bodies
                                  c-lineup-gcc-asm-reg))
    (c-set-offset 'arglist-cont-nonempty '(c-lineup-ternary-bodies
                                           c-lineup-gcc-asm-reg
                                           c-lineup-arglist))
    (c-set-offset 'statement-cont '(c-lineup-ternary-bodies +))

** browse-url

*** Added support for custom URL handlers.
There is a new variable 'browse-url-default-handlers' and a user
option 'browse-url-handlers' being alists with '(REGEXP-OR-PREDICATE
. FUNCTION)' entries allowing to define different browsing FUNCTIONs
depending on the URL to be browsed.  The variable is for default
handlers provided by Emacs itself or external packages, the user
option is for the user (and allows for overriding the default
handlers).

Formerly, one could do the same by setting
'browse-url-browser-function' to such an alist.  This usage is still
supported but deprecated.

*** Categorization of browsing functions in internal vs. external.
All standard browsing functions such as 'browse-url-firefox',
'browse-url-mail', or 'eww' have been categorized into internal (URL
is browsed in Emacs) or external (an external application is spawned
with the URL).  This is done by adding a 'browse-url-browser-kind'
symbol property to the browsing functions.  With a new command
'browse-url-with-browser-kind', an URL can explicitly be browsed with
either an internal or external browser.

*** Support for the conkeror browser is now obsolete.

** SHR

---
*** The command 'shr-browse-url' now supports custom mailto handlers.
Clicking on or otherwise following a 'mailto:' link in a HTML buffer
rendered by SHR previously invoked the command 'browse-url-mailto'.
This is still the case by default, but if you customize
'browse-url-mailto-function' or 'browse-url-handlers' to call some
other function, it will now be called instead of the default.

+++
*** New variable 'shr-max-width'.
If this variable is non-nil, and 'shr-width' is nil, then SHR will use
the value of 'shr-max-width' to limit the width of the rendered HTML.
The default is 120 characters, so even if you have very wide frames,
HTML text will be rendered more narrowly, which usually leads to a
more readable text.  Set this variable to nil to get the previous
behavior of rendering as wide as the window-width allows.  If
'shr-width' is non-nil, it overrides this variable.

** EWW

---
*** The command 'eww-follow-link' now supports custom mailto handlers.
The function that is invoked when clicking on or otherwise following a
'mailto:' link in an EWW buffer can now be customized.  For more
information, see the related entry about 'shr-browse-url' above.

** Project

*** New user option 'project-vc-merge-submodules'.

*** Project commands now have their own history.
Previously used project directories are now suggested by all commands
that prompt for a project directory.

+++
*** New prefix keymap 'project-prefix-map'.
Key sequences that invoke project-related commands start with the
prefix 'C-x p'.  Type "C-x p C-h" to show the full list.

+++
*** New commands 'project-dired', 'project-vc-dir', 'project-shell',
'project-eshell'.  These commands run Dired/VC-Dir and Shell/Eshell in
a project's root directory, respectively.

+++
*** New command 'project-compile'.
This command runs compilation in the current project's root
directory.

+++
*** New command 'project-switch-project'.
This command lets you "switch" to another project and run a project
command chosen from a dispatch menu.

+++
*** New user option 'project-list-file'.

** json.el

---
*** JSON number parsing is now stricter.
Numbers with a leading plus sign, leading zeros, or a missing integer
component are now rejected by 'json-read' and friends.  This makes
them more compliant with the JSON specification and consistent with
the native JSON parsing functions.

** xml.el

*** XML serialization functions now reject invalid characters.
Previously 'xml-print' would produce invalid XML when given a string
with characters that are not valid in XML (see
https://www.w3.org/TR/xml/#charsets).  Now it rejects such strings.

** Battery

---
*** UPower is now the default battery status backend when available.
UPower support via the function 'battery-upower' was added in Emacs
26.1, but was disabled by default.  It is now the default value of
'battery-status-function' when the system provides a UPower D-Bus
service.  The user options 'battery-upower-device' and
'battery-upower-subscribe' control which power sources to query and
whether to respond to status change notifications in addition to
polling, respectively.

---
*** A richer syntax can be used to format battery status information.
The user options 'battery-mode-line-format' and
'battery-echo-area-format' now support the full formatting syntax of
the function 'format-spec' documented under node "(elisp) Custom Format
Strings".  The new syntax includes specifiers for padding and
truncation, amongst other things.

** bug-reference.el

---
*** Bug reference mode auto-setup.  If 'bug-reference-mode' or
'bug-reference-prog-mode' have been activated, their respective hook
has been run and still 'bug-reference-bug-regexp' and
'bug-reference-url-format' aren't both set, it tries to guess
appropriate values for those two variables.  There are three guessing
mechanisms so far: based on version control information of the current
buffer's file, based on newsgroup/mail-folder name and several news
and mail message headers in Gnus buffers, and based on IRC channel and
network in rcirc and ERC buffers.  All mechanisms are extensible with
custom rules, see the variables 'bug-reference-setup-from-vc-alist',
'bug-reference-setup-from-mail-alist', and
'bug-reference-setup-from-irc-alist'.

\f
* New Modes and Packages in Emacs 28.1

** Lisp Data mode

The new command 'lisp-data-mode' enables a major mode for buffers
composed of Lisp symbolic expressions that do not form a computer
program.  The ".dir-locals.el" file is automatically set to use this
mode, as are other data files produced by Emacs.

\f
* Incompatible Editing Changes in Emacs 28.1

** In 'nroff-mode', 'center-line' is now bound to 'M-o M-s'.
The original key binding was 'M-s', which interfered with I-search,
since the latter uses 'M-s' as a prefix key of the search prefix map.

** 'vc-print-branch-log' shows the change log for BRANCH from its root
directory instead of the default directory.

\f
* Incompatible Lisp Changes in Emacs 28.1

** 'equal' no longer examines some contents of window configurations.
Instead, it considers window configurations to be equal only if they
are 'eq'.  To compare contents, use 'compare-window-configurations'
instead.  This change helps fix a bug in 'sxhash-equal', which returned
incorrect hashes for window configurations and some other objects.

** When its first argument is a string, 'make-text-button' no longer
modifies the string's text properties; instead, it uses and returns
a copy of the string.  This helps avoid trouble when strings are
shared or constants.

---
** The obsolete function 'thread-alive-p' has been removed.

** 'dns-query' now consistently uses Lisp integers to represent integers.
Formerly it made an exception for integer components of SOA records,
because SOA serial numbers can exceed fixnum ranges on 32-bit platforms.
Emacs now supports bignums so this old glitch is no longer needed.

** The Lisp variables 'previous-system-messages-locale' and
'previous-system-time-locale' have been removed, as they were created
by mistake and were not useful to Lisp code.

** The 'load-dangerous-libraries' variable is now obsolete.
It was used to allow loading Lisp libraries compiled by XEmacs, a
modified version of Emacs which is no longer actively maintained.
This is no longer supported, and setting this variable has no effect.

+++
** The macro 'with-displayed-buffer-window' is now obsolete.
Use macro 'with-current-buffer-window' with action alist entry 'body-function'.

** The metamail.el library is now marked obsolete.

---
** Some obsolete variable and function aliases in dbus.el have been removed.
In Emacs 24.3, the variable 'dbus-event-error-hooks' was renamed to
'dbus-event-error-functions' and the function
'dbus-call-method-non-blocking' was renamed to 'dbus-call-method'.
The old names, which were kept as obsolete aliases of the new names,
have now been removed.

---
** Some libraries obsolete since Emacs 23 have been removed:
'ledit.el', 'lmenu.el', 'lucid.el and 'old-whitespace.el'.

\f
* Lisp Changes in Emacs 28.1

+++
** New function 'file-modes-number-to-symbolic' to convert a numeric
file mode specification into symbolic form.

** New macro 'dlet' to dynamically bind variables.

** The variable 'force-new-style-backquotes' has been removed.
This removes the final remaining trace of old-style backquotes.

** The module header 'emacs-module.h' now contains type aliases
'emacs_function' and 'emacs_finalizer' for module functions and
finalizers, respectively.

** Module functions can now install an optional finalizer that is
called when the function object is garbage-collected.  Use
'set_function_finalizer' to set the finalizer and
'get_function_finalizer' to retrieve it.

** Modules can now open a channel to an existing pipe process using
the new module function 'open_channel'.  Modules can use this
functionality to asynchronously send data back to Emacs.

** 'file-modes', 'set-file-modes', and 'set-file-times' now have an
optional argument specifying whether to follow symbolic links.

** 'parse-time-string' can now parse ISO 8601 format strings,
such as "2020-01-15T16:12:21-08:00".

+++
** The new function 'dom-remove-attribute' has been added.

---
** 'make-network-process', 'make-serial-process' ':coding' behavior change.
Previously, passing ':coding nil' to either of these functions would
override any non-nil binding for 'coding-system-for-read' and
'coding-system-for-write'.  For consistency with 'make-process' and
'make-pipe-process', passing ':coding nil' is now ignored.  No code in
Emacs depended on the previous behavior; if you really want the
process' coding-system to be nil, use 'set-process-coding-system'
after the process has been created, or pass in ':coding '(nil nil)'.

+++
** 'open-network-stream' now accepts a ':coding' argument.
This allows specifying the coding systems used by a network process
for encoding and decoding without having to bind
'coding-system-for-{read,write}' or call 'set-process-coding-system'.

+++
** 'open-network-stream' can now take a :capability-command that's a function.
The function is called with the greeting from the server as its only
parameter, and allows sending different TLS capability commands to the
server based on that greeting.

+++
** 'open-gnutls-stream' now also accepts a ':coding' argument.

+++
** New user option 'process-file-return-signal-string'.
It controls, whether 'process-file' returns a string when a remote
process is interrupted by a signal.

+++
** The behavior of 'format-spec' is now closer to that of 'format'.
In order for the two functions to behave more consistently,
'format-spec' now pads and truncates based on string width rather than
length, and also supports format specifications that include a
truncating precision field, such as '%.2a'.

---
** New function 'color-values-from-color-spec'.
This can be used to parse RGB color specs in several formats and
convert them to a list '(R G B)' of primary color values.

\f
* Changes in Emacs 28.1 on Non-Free Operating Systems

+++
** On macOS, Emacs can now load dynamic modules with a ".dylib" suffix.
'module-file-suffix' now has the value ".dylib" on macOS, but the
".so" suffix is supported as well.

+++
** On MS-Windows, Emacs can now toggle the IME.
A new function 'w32-set-ime-open-status' can now be used to disable
and enable the MS-Windows native Input Method Editor (IME) at run
time.  A companion function 'w32-get-ime-open-status' returns the
current IME activation status.

+++
** On MS-Windows, Emacs can now use the native image API to display images.
Emacs can now use the MS-Windows GDI+ library to load and display
images in JPEG, PNG, GIF and TIFF formats.  This support is enabled
unless Emacs was configured '--without-native-image-api'.

This feature is experimental, and needs to be turned on to be used.
