For those users who live backwards in time, here is information
|
|
about downgrading to Emacs version 28.2. We hope you will enjoy the
|
|
greater simplicity that results from the absence of many @w{Emacs
|
|
@value{EMACSVER}} features.

Like its newer releases, Emacs 28 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 deleted the
|
|
capability of ahead-of-time native compilation of all the Lisp files
|
|
that come with Emacs. This makes the Emacs build process much faster.
|
|

Emacs can no longer be built with the tree-sitter library, so you no
|
|
longer will need to look for and install the grammar libraries for
|
|
the languages in which you want to program. Similarly, all the modes
|
|
that are based on the tree-sitter library were deleted, leaving you
|
|
with just one major mode for every supported programming language: no
|
|
more need to decide whether to turn the tree-sitter supported modes on
|
|
and try using their parser-based fontification, indentation, and other
|
|
features. For some languages and file types, this means no major mode
|
|
at all, leaving you with the venerable Fundamental mode as the
|
|
natural, high-performance choice. For example, Go, Rust, and CMake
|
|
files no longer have any major modes for editing their files ---
|
|
another milestone towards a simpler, leaner Emacs.
|
|
|
|
@item
|
|
Built-in support for accessing SQLite databases was removed. You can
|
|
now again edit SQLite files as simple binary files, which Emacs is
|
|
quite capable to support, as it always did.
|
|
|
|
@item
|
|
As a gesture to users of the Haiku operating system, we've dropped the
|
|
code which allowed Emacs to be built on that OS@. We expect Haiku
|
|
users to enjoy the much simpler editors they have for editing their
|
|
files.
|
|

Support for XInput2 input events on X is gone. We think the
|
|
traditional X input events are more than enough, certainly so as you
|
|
move back in time, where XInput2 will eventually be removed from X as
|
|
well, once the maintainers of the X Windows system realize the utter
|
|
futility of supporting fancy input mechanisms.
|
|
|
|
@item
|
|
The ``pure GTK'' (a.k.a.@: @acronym{PGTK}) configuration of Emacs is
|
|
no longer supported. This is in anticipation of the complete removal
|
|
of the GTK toolkit support from Emacs, and in accordance with our
|
|
expectation that GTK will cease to exist as you move back in time. We
|
|
plan on removing support for all the other toolkits as well, leaving
|
|
only the pure X build with our own widgets as the single supported GUI
|
|
configuration on X.
|
|
|
|
@item
|
|
The @option{--init-directory} command-line option was removed, as
|
|
initializing Emacs with init files of another user is a preposterous
|
|
idea anyway.
|
|
|
|
@item
|
|
In line with simplifying and eventually removing the
|
|
native-compilation option, we've deleted the
|
|
@option{--with-native-compilation=aot} configure-time option. This
|
|
greatly simplifies how native compilation works and makes your
|
|
configure-time decision regarding native compilation in Emacs
|
|
clear-cut: either Emacs compiles non-preloaded Lisp packages to native
|
|
code only before using it, or it never uses native compilation at all;
|
|
no more half measures and special exceptions. For similar reasons,
|
|
@code{native-compile-prune-cache} and
|
|
@code{startup-redirect-eln-cache} features are no longer part of
|
|
Emacs.
|
|
|
|
@item
|
|
We've deleted the special code and features which allowed Emacs to
|
|
present decent performance and responsiveness when editing files with
|
|
very long lines. Such files become more and more rare as time goes
|
|
back, and so having all this tricky code in Emacs for their benefit
|
|
was deemed an unnecessary complication.
|
|
|
|
@item
|
|
Emacs dropped support for Eglot and the LSP servers. We decided that
|
|
the built-in ways of analyzing source code are more than enough as you
|
|
move back in time.
|
|
|
|
@item
|
|
Commands to scale and rotate images are once again bound to single
|
|
keys like @kbd{+}, @kbd{-}, and @kbd{r}, which makes them much easier
|
|
to type. As for the risk of typing these by mistake, we don't believe
|
|
Emacs users make typing mistakes, especially as they move back in
|
|
time and become younger and younger.
|
|
|
|
@item
|
|
To simplify typing popular commands, we've rebound the @w{@kbd{C-x 8 . .}}
|
|
back to @w{@kbd{C-x 8 .}} and @w{@kbd{C-x 8 = =}} back to @w{@kbd{C-x 8 =}}.
|
|
There's no need for fancier, longer key sequences, as moving back in
|
|
time means we will have fewer and fewer commands to bind to them in
|
|
the first place.
|
|
|
|

|
If you inadvertently kill the @file{*scratch*} buffer, Emacs will
|
|
recreate it in Fundamental mode, not in Lisp Interaction mode. You
|
|
get to turn on the mode you like yourself. Our long-term plans for
|
|
past Emacs releases is to remove the recreation of @file{*scratch*}
|
|
altogether, and this is the first step in that direction.
|
|
|
|
@item
|
|
Support for @code{rlogin} and @code{rsh} protocols are back, since we
|
|
expect them to become more and more important and popular as you move
|
|
back in time.

In preparation for eventual removal of Unicode support from Emacs,
|
|
we've downgraded our Unicode support to version 14.0.

@item
|
|
You can no longer change the size of the font globally. Since Emacs
|
|
will at some past date remove all support for variable-size fonts,
|
|
having such commands is a luxury we are better without.
|
|
|
|
@item
|
|
On our permanent quest for simplifying Emacs, we've removed the
|
|
commands @code{duplicate-line} and @code{duplicate-dwim}; the old-time
|
|
friends @kbd{M-w} and @kbd{C-y} (typed one or more times) should
|
|
suffice. The command @code{rename-visited-file} is gone for the same
|
|
reason.
|
|
|
|
@item
|
|
We've deleted many commands related to Emoji, which were bound in the
|
|
@kbd{C-x 8 e} prefix keymap. We decided that the ability to type
|
|
Emoji sequences using @kbd{C-x 8 @key{RET}} is enough, and actually
|
|
serves our users better by requiring them to know the codepoints of
|
|
the sequences they want to type.
|
|
|
|
@item
|
|
We dropped support for many scripts and input methods, especially old
|
|
scripts that no one uses anyway. For similar reasons, Greek and
|
|
Ukrainian translations of the Emacs tutorial are not available
|
|
anymore.
|
|
|
|
@item
|
|
@file{package.el} can no longer fetch source code of packages from
|
|
their VCS repositories. We think command-line tools like Git should
|
|
be enough to allow you to clone their repositories. So we deleted
|
|
the @code{package-vc-install} command and other similar commands.
|
|
|
|
@item
|
|
To keep up with decreasing computer memory capacity and disk space, many
|
|
other functions and files have been eliminated in Emacs 28.2.
