** X selection requests are now handled much faster and asynchronously.
This means it should be less necessary to disable the likes of
-`select-active-regions' when Emacs is running over a slow network
+'select-active-regions' when Emacs is running over a slow network
connection.
** Emacs now updates invisible frames that are made visible by a compositor.
If an invisible or an iconified frame is shown to the user by the
compositing manager, Emacs will now redisplay such a frame even though
-'frame-visible-' returns nil or 'icon' for it. This can happen, for
+'frame-visible-p' returns nil or 'icon' for it. This can happen, for
example, as part of preview for iconified frames.

treesit.el now unconditionally sets 'transpose-sexps-function' for all

-** The highly accessible Modus themes collection has six items
+** The highly accessible Modus themes collection has six items.
The 'modus-operandi' and 'modus-vivendi' are the main themes that have
been part of Emacs since version 28. The former is light, the latter
dark. In addition to these, we now have 'modus-operandi-tinted' and
'modus-vivendi-tinted' for easier legibility, as well as
'modus-operandi-deuteranopia' and 'modus-vivendi-deuteranopia' to
cover the needs of users with red-green color deficiency. The Info
-manual of the themes describes the details and showcases all their
-customization options.

* Incompatible Lisp Changes in Emacs 30.1
+** User option 'tramp-completion-reread-directory-timeout' has been removed.
+This user option has been obsoleted in Emacs 27, use
+'remote-file-name-inhibit-cache' instead.
+
\f
* Lisp Changes in Emacs 30.1
'unless', 'ignore-error' and 'with-suppressed-warnings' in addition to
the existing warnings for 'let' and 'let*'. Example:
- (when (> x 2))
+ (when (> x 2))
This warning can be suppressed using 'with-suppressed-warnings' with
the warning name 'empty-body'.
The compiler now warns about quoted condition (error) names
in 'condition-case' and 'ignore-error'. Example:
- (condition-case nil
- (/ x y)
- ('arith-error "division by zero"))
+ (condition-case nil
+ (/ x y)
+ ('arith-error "division by zero"))
Quoting them adds the error name 'quote' to those handled or ignored
respectively, which was probably not intended.
string, cons, vector, record, function, large integer or float as this
may not match any value at all. Example:
- (eq x "hello")
+ (eq x "hello")
Only literals for symbols and small integers (fixnums), including
characters, are guaranteed to have a consistent (unique) identity.
This warning can be suppressed using 'with-suppressed-warnings' with
the warning name 'suspicious'.
