@item
Emacs now optionally supports native compilation of Lisp files. This
can improves performance significantly in some cases. To enable this,
-configure Emacs with the '--with-native-compilation' option.
+configure Emacs with the @option{--with-native-compilation} option.
@item
The new NonGNU ELPA archive is enabled by default alongside GNU ELPA.
@item
The Cairo graphics library is now used by default if present.
+@item
+On GNU/Linux, Emacs now supports loading Secure Computing filters. To
+use this feature, invoke Emacs with the @option{--seccomp=@var{file}}
+command-line switch, where @var{file} names a binary file that defines
+the filtering. See the manual page of the @code{seccomp} system call
+for more details.
+
@item
The new themes @samp{modus-vivendi} and @samp{modus-operandi} have
been added. They are designed to conform with the highest standard
New system for displaying documentation for groups of functions
(@kbd{M-x shortdoc-display-group RET}).
+@item
+Emacs can now support 24-bit color text-mode terminals even if their
+terminfo database doesn't state this support in a standard way. Set
+the @env{COLORTERM} environment variable to the value @samp{truecolor}
+to activate this.
+
+@item
+The @code{strike-through} face attribute is now supported on capable
+text-mode terminals.
+
+@item
+@code{xterm-mouse-mode} supports TTY menus.
+
+@item
+A new minor mode @code{context-menu-mode} causes @code{mouse-3}
+(a.k.a.@: ``right-clicks'') of the mouse to pop up context-dependent
+menus.
+
+@item
+Prefix commands to control the display of the results of the next
+command. @kbd{C-x 4 4 @var{command}} displays the result of
+@var{command} in a new window. @kbd{C-x 5 5 @var{command}} displays
+the results of @var{command} in a new frame.
+
+@item
+Emacs now supports ``transient'' input methods. A transient input
+method is enabled for inserting a single character, and is then
+automatically disabled. Select a transient input method with @kbd{C-u
+C-x \}; enable it (for inserting a single character) with @kbd{C-x \}.
+New input methods @code{compose} (based on X Window System Multi_key
+sequences) and @code{iso-transl} are especially convenient with this
+feature, when you need to insert a single special character.
+
+@item
+@kbd{M-y}, when invoked after a command that is not a yank command,
+allows selection of one of the previous kills.
+
+@item
+New minor mode @code{repeat-mode} allows to repeat commands with fewer
+keystrokes.
+
@item
Among the many internal changes in this release, we would like to
highlight that all files in the tree now use @code{lexical-binding}.
