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.
