+
+Here's a list of the most important changes in Emacs 30 as compared to
+Emacs 29.  The full list is too long to fit here, but can be read in the
+Emacs @file{NEWS} file by typing @kbd{C-h n} inside Emacs.
+
+@itemize
+@item
+Native compilation is now enabled by default.  When Emacs is built on a
+machine with @samp{libgccjit}, this will improve Emacs performance in
+many typical workloads.
+
+@item
+Emacs has been ported to the Android operating system.  See the file
+@file{java/INSTALL} in the Emacs source distribution for details on how
+to build it.
+
+@item
+Numerous performance improvements, for example in parsing JSON, reading
+data from subprocesses, handling output from Eshell and in Shell mode, X
+selection requests, remote files, and so on.
+
+@item
+Native JSON support is now always available; libjansson is no longer
+used.
+
+@item
+New major modes based on the
+@uref{https://tree-sitter.github.io/tree-sitter/, tree-sitter library}
+library for editing Elixir, HTML, Lua, HEEx, and PHP.
+
+@item
+Support for the EditorConfig standard has been added, an editor-neutral
+way to provide directory local (project-wide) settings.  It is enabled
+via a new global minor mode 'editorconfig-mode' which makes Emacs obey
+the '.editorconfig' files.
+
+@item
+Support for touchscreens has been improved.  On systems that understand
+them (at present X, Android, PGTK, and MS-Windows), many touch screen
+gestures are now implemented and translated into mouse or gesture
+events, and support for tapping tool bar buttons and opening menus has
+been added.
+
+@item
+Tool bar tweaks.  The new minor mode 'window-tool-bar-mode' provides a
+per-window toolbar.  Toolbars can be placed on the bottom of a frame by
+setting the @code{tool-bar-position} variable on all window systems but
+NextStep and macOS.
+
+@item
+The @samp{which-key} package from GNU ELPA is now included in Emacs.
+After enabling the minor mode mode @code{which-key-mode}, if you enter
+@kbd{C-x} and wait for one second, the minibuffer will expand with all
+available key bindings that follow @kbd{C-x} (or as many as space
+allows).
+
+@item
+New global minor mode @code{kill-ring-deindent-mode}.  When enabled,
+text being saved to the kill ring will be de-indented by the column
+number at its start.
+
+@item
+New minor mode @code{visual-wrap-prefix-mode}.  Unlike @kbd{M-q}, the
+indentation only happens on display, and doesn't change the buffer text
+in any way.
+
+@item
+Automatic regeneration of TAGS files using the new global minor mode
+@code{etags-regen-mode}.
+
+@item
+Improved warnings from the byte-code compiler to aid Lisp developers.
+
+@item
+Support for underline colors on TTY frames.
