* 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
* Changes in Specialized Modes and Packages in Emacs 28.1

** Flyspell mode

+++
*** Corrections and actions menu is now also bound to mouse-3.
When Flyspell mode highlights a word as misspelled, you can click on
it to display a menu of possible corrections and actions.  In addition
to being bound to mouse-2 (usually the middle mouse button), it is now
also bound to mouse-3 (usually the right mouse button).

\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.
