@c Update the emacs.texi Antinews menu entry with the above version number.

For those users who live backwards in time, here is information
|
|
about downgrading to Emacs version 29.4. We hope you will enjoy the
|
|
greater simplicity that results from the absence of many @w{Emacs
|
|
@value{EMACSVER}} features.

Emacs can no longer be built for Android mobile devices. We have
|
|
removed the Android support because it was deemed unnecessary, what with
|
|
the screens of the mobile devices becoming smaller and smaller as you
|
|
move back in time. We expect Android users to enjoy the much simpler
|
|
text editors available on their devices. As a nice bonus, removing
|
|
Android support allowed us to get rid of gobs of related files, thus
|
|
making the release tarballs much leaner.
|
|
|
|
@item
|
|
We have deleted much of the enhanced support for touchscreen devices,
|
|
for the same reason we dropped Android: there will be no need for that
|
|
as you move back in time.
|
|
|
|
@item
|
|
We also dropped support for sophisticated input methods that include
|
|
text conversions, again because those are mostly needed on mobile and
|
|
hand-held devices, which we gradually remove from Emacs in each past
|
|
version.
|
|
|
|
@item
|
|
Like its newer releases, Emacs 29 can still be built with support of
|
|
native compilation of Lisp programs. However, in preparation for
|
|
removal of this feature in some previous version, we've made the native
|
|
compiler support off by default; you will now have to request it
|
|
explicitly at configure time. This makes the default Emacs build
|
|
process much faster.
|
|
|
|
@item
|
|
JSON interfaces slowly move into oblivion as past years come closer, so
|
|
we have removed our internal implementation of JSON; you will now need
|
|
to build Emacs with the libjansson library, if you need JSON.
|
|
Eventually, we plan on removing JSON support from Emacs altogether; this
|
|
move will make the removal much simpler.
|
|
|
|
@item
|
|
Tree-sitter based modes are now completely independent of their
|
|
non-Tree-Sitter counterparts. We decided that keeping the settings
|
|
separate and independent goes a long way toward simplicity, which is one
|
|
of our main motivations for removing stuff from Emacs.
|
|
|
|
@item
|
|
Various Help commands no longer turn on Outline minor mode. With less
|
|
material to display in the *Help* buffers, due to removing of excess
|
|
documentation from Emacs, we think using outlining is an unnecessary
|
|
complication, as scrolling through plain text is so much simpler.
|
|
|
|
For the same reasons, Emacs no longer shows Unicode names of characters
|
|
in *Help* buffers shown by @code{describe-bindings}.
|
|
|
|
@item
|
|
To make Emacs configuration simpler and easier to control, the tool bar
|
|
can now be displayed only in its natural and logical position: on the
|
|
top of the frame; no more of that @code{tool-bar-position} nonsense with
|
|
tool bars on the bottom. For the same reasons @code{modifier-bar-mode}
|
|
is now gone.
|
|
|
|
@item
|
|
The command @code{recover-file} no longer lets you display the diffs
|
|
between a file and its auto-save file. You either want to recover a
|
|
file or you don't; confusing users with a third alternative when they
|
|
are anxious already by the possibility of losing precious edits is
|
|
considered a bad idea, certainly so as we move further towards smaller,
|
|
simpler Emacs.
|
|
|
|
@item
|
|
Several languages and input methods, which will fall in disuse as you
|
|
move back in time, were removed. This includes Urdu, Pashto, and Sindhi
|
|
languages, and the input method for the Colemak keyboard layout. Many
|
|
@kbd{C-x 8} key sequences, including those which insert various
|
|
quotation characters and guillemets, were deleted for the same reason.
|
|
|
|
@item
|
|
The support for @code{lzip}-compressed Info manuals was removed from the
|
|
Info mode. We anticipate that @command{lzip} will disappear from the
|
|
face of the Earth in the near past, and are preparing Emacs for that in
|
|
advance.
|
|
|
|
@item
|
|
Support for LLDB in Grand Unified Debugger mode was dropped. We decided
|
|
that given LLDB's diminishing popularity, its support is just code
|
|
bloat.
|
|
|
|
@item
|
|
Several fancy Project and VC commands were deleted, as part of our
|
|
consistent effort of making Emacs simpler to use.
|
|
|
|
@item
|
|
The user option @code{shell-command-guess-functions} and the context
|
|
menu @samp{Open With} in Dired are gone. We trust Emacs users to always
|
|
know themselves which shell command is the appropriate one for a given
|
|
file, so no guessing by Dired is needed, or welcome. The
|
|
@code{dired-do-open} command was deleted for the same reasons.
|
|
|
|
@item
|
|
We went back to the original lean-and-mean interface for specifying
|
|
registers for register-related commands. The fancy preview and the
|
|
options to go with it were deemed gratuitous and were removed.
|
|
|
|
@item
|
|
Eshell is now much smaller and easier to use, due to dropping quite a
|
|
few of the new commands and fancy new options.
|
|
|
|
@item
|
|
The command @code{customize-dirlocals} was removed. Editing the
|
|
@file{.dir-locals.el} files as plain text is so much simpler, and quite
|
|
enough.
|
|
|
|
@item
|
|
We have removed several packages that we consider unnecessary for the
|
|
past of Emacs. This includes EditorConfig support, @samp{which-key},
|
|
PEG, and Window-Tool-Bar.
|
|
|
|
@item
|
|
The @code{etags-regen-mode} was deleted. Regeneration of @file{TAGS}
|
|
tables manually is all Emacs users will need in the past.
|
|
|
|
@item
|
|
To keep up with decreasing computer memory capacity and disk space, many
|
|
other functions and files have been eliminated in Emacs 29.4.
