GNU Emacs NEWS -- history of user-visible changes.

Copyright (C) 2022-2026 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 32.
|
||
|
||
See file HISTORY for a list of GNU Emacs versions and release dates.
|
||
See files NEWS.31, NEWS.30, ..., 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.

** Emacs no longer kills child processes after EPIPE.
|
||
Previously, Emacs would immediately kill a child process and set its
|
||
exit status to 256 if sending input to that process returned EPIPE.
|
||
Now when this happens, Emacs closes the file descriptor to write to the
|
||
child process, but allows it to continue execution as normal.

*** Package-vc can copy local changes from existing installations.
|
||
When installing the latest release of a package, 'package-vc' will
|
||
propose copying files from an existing tarball installation of the same
|
||
package with the same version. This is useful if you have started
|
||
making local changes to your tarball installation, and then decided to
|
||
check out the repository to prepare a patch for the package maintainer.

** New variable 'completion-frontend-properties'.
|
||
This variable generalizes the 'completion-lazy-hilit' variable added in
|
||
Emacs 30. It allows Lisp programs that present completion candidates
|
||
("completion frontends") to provide additional information which can be
|
||
used to adjust or optimize completion candidates computation.
|
||
|
||
** D-Bus
|
||
|
||
+++
|
||
*** Support error handler in asynchronous method calls.
|
||
The HANDLER argument of 'dbus-call-method-asynchronously' can be a cons
|
||
cell '(HANDLER . ERROR-HANDLER)'. ERROR-HANDLER is invoked if the
|
||
method call returns with a D-Bus error; the error is passed as argument.
