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

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 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.

* Editing Changes in Emacs 28.1
|

|
||
+++
|
||
** '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.
|
||
|
||
|
||
* Changes in Specialized Modes and Packages in Emacs 28.1
|
||
|
||
** Help
|
||
|
||
+++
|
||
*** New command 'describe-keymap' describes keybindings in a keymap.
|
||
|
||
---
|
||
** 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.
|
||
|
||
** Tramp
|
||
|
||
+++
|
||
*** New connection method "media", which allows accessing media devices
|
||
like cell phones, tablets or cameras.
|
||
|
||
** 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
|
||
/ / package-menu-filter-clear
|
||
|
||
|
||
* 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.
|
||
|
||
** 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.
|
||
|
||
|
||
* 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.
