| | GNU Emacs NEWS -- history of user-visible changes.
Copyright (C) 2017-2020 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 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.
\f
* 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.

\f

\f
* New Modes and Packages in Emacs 28.1
\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.
** The obsolete function 'thread-alive-p' has been removed.
\f
* 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.
\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.

** '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.
