| | GNU Emacs NEWS -- history of user-visible changes.
Copyright (C) 2021-2022 Free Software Foundation, Inc.
See the end of the file for license conditions.
Please send Emacs bug reports to 'bug-gnu-emacs@gnu.org'.
If possible, use 'M-x report-emacs-bug'.
This file is about changes in Emacs version 30.
See file HISTORY for a list of GNU Emacs versions and release dates.
See files NEWS.29, NEWS.28, ..., NEWS.18, and NEWS.1-17 for changes
in older Emacs versions.
You can narrow news to a specific version by calling 'view-emacs-news'
with a prefix argument or by typing 'C-u C-h C-n'.
Temporary note:
+++ indicates that all relevant manuals in doc/ have been updated.
--- means no change in the manuals is needed.
When you add a new item, use the appropriate mark if you are sure it
applies, and please also update docstrings as needed.

\f
* Changes in Emacs 30.1
** X selection requests are now handled much faster and asynchronously.
This means it should be less necessary to disable the likes of
`select-active-regions' when Emacs is running over a slow network
connection.

* Editing Changes in Emacs 30.1
\f
* Changes in Specialized Modes and Packages in Emacs 30.1
---
** Variable order and truncation can now be configured in gdb-many-window mode.
The new variable 'gdb-locals-table-row-config' allows users to
configure the order and max length of various properties in the local
variables buffer when using 'gdb-many-windows'.
By default, this variable is set to write the properties in the order:
name, type and value, where the name and type are truncated to 20
characters, and the value is truncated according to the value of
'gdb-locals-value-limit'.
If you want to get back the old behavior, set
'gdb-locals-table-row-config' to the value
((type . 0)(name . 0)(value . ,gdb-locals-value-limit)).
** VC
---
*** New user option 'vc-git-shortlog-switches'.
This is a string or a list of strings that specifies the Git log
switches for shortlogs, such as the one produced by 'C-x v L'.
'vc-git-log-switches' is no longer used for shortlogs.
** bs
---
*** New user option 'bs-default-action-list'.
You can now configure how to display the "*buffer-selection*" buffer
using this new option. (Or set 'display-buffer-alist' directly.)
** Eshell
+++
*** New splice operator for Eshell dollar expansions.
Dollar expansions in Eshell now let you splice the elements of the
expansion in-place using '$@expr'. This makes it easier to fill lists
of arguments into a command, such as when defining aliases. For more
information, see the "(eshell) Dollars Expansion" node in the Eshell
manual.
+++
*** 'eshell-read-aliases-list' is now an interactive command.
After manually editing 'eshell-aliases-file', you can use
'M-x eshell-read-aliases-list' to load the edited aliases.
** Prog Mode
+++
*** New command 'prog-fill-reindent-defun'
This command either fills a single paragraph in a defun, such as a
doc-string, or a comment, or (re)indents the surrounding defun if
point is not in a comment or a string. It is by default bound to
'M-q' in 'prog-mode' and all its descendants.
** Scheme mode
---
*** Auto-detection of Scheme library files.
Emacs now automatically enables the Scheme mode when opening R6RS
Scheme Library Source ('.sls') files and R7RS Scheme Library
Definition ('.sld') files.
---
*** Imenu members for R6RS and R7RS library members.
Imenu now lists the members directly nested in R6RS Scheme libraries
('library') and R7RS libraries ('define-library').
