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 28.
|
||
|
||
See file HISTORY for a list of GNU Emacs versions and release dates.
|
||
See files NEWS.27, NEWS.26, ..., 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.

||
* Installation Changes in Emacs 28.1
|
||
|
||
** Cairo is now used by default if found.
|
||
'--with-cairo' is now the default, if the appropriate development files
|
||
are found by 'configure'
|
||
|
||
---
|
||
** The ftx font backend driver has been removed.
|
||
It was declared obsolete in Emacs 27.1.
|
||
|
||
|
||
* Startup Changes in Emacs 28.1
|
||
|
||
|
||
* Changes in Emacs 28.1
|
||
|
||
|
||
* Editing Changes in Emacs 28.1
|
||
|
||
|
||
* Changes in Specialized Modes and Packages in Emacs 28.1
|
||
|
||
|
||
* New Modes and Packages in Emacs 28.1
|
||
|
||
|
||
* 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.
|
||
|
||
** 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.
|
||
|
||
|
||
* Lisp Changes in Emacs 28.1
|
||
|
||
** 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.
|
||
|
||
** 'parse-time-string' can now parse ISO 8601 format strings,
|
||
such as "2020-01-15T16:12:21-08:00".
|
||
|
||
|
||
* 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.

||
** '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.

coding: utf-8

mode: outline
