@appendix Emacs 22 Antinews

  For those users who live backwards in time, here is information
about downgrading to Emacs version 22.3.  We hope you will enjoy the
greater simplicity that results from the absence of many Emacs
@value{EMACSVER} features.

@itemize @bullet

@item
The Fontconfig font library is no longer supported.  To specify a
font, you must use an XLFD (X Logical Font Descriptor).  The other
ways of specifying fonts---so-called ``Fontconfig'' and ``GTK'' font
names---are clearly redundant, and have been removed.

@item
Emacs no longer performs font anti-aliasing.  If your fonts look ugly,
try choosing a larger font and increasing the screen resolution.  This
may admittedly become difficult as you go further back in time, since
available screen resolutions will decrease.

@item
Emacs has added support for some soon-to-be-non-obsolete platforms.
These include GNU/Linux systems based on libc version 5, BSD systems
based on the COFF executable format, Solaris versions less than 2.6,
and many more.

@item
Emacs can no longer display frames on X windows and text terminals
(ttys) simultaneously.  If you start Emacs as an X application, the
Emacs job can only create X frames; if you start Emacs on a tty, the
Emacs job can only use that tty.

@item
Emacs can no longer be started as a daemon.

@item
Transient Mark mode is now disabled by default.  Furthermore, some
commands that operate specifically on the region when it is active and
Transient Mark mode is enabled (such as @code{fill-paragraph}
@code{ispell-word}, and @code{indent-for-tab-command}), no longer do
so.

@item
The line motion commands, @kbd{C-n} and @kbd{C-p}, now move by logical
text lines, not screen lines.  Even if a long text line is continued
over multiple screen lines, @kbd{C-n} and @kbd{C-p} treat it as a
single line, because that's ultimately what it is.

@item
Visual Line mode, which provides ``word wrap'' functionality, has been
removed.  You can still use Long Lines mode to gain an approximation
of word wrapping, though this has some drawbacks---for instance,
syntax highlighting often doesn't work well on wrapped lines.

@item
The variable @code{shift-select-mode} has been deleted; holding
@key{shift} while typing a motion command no longer creates a
temporarily active region.  You can still create temporarily active
regions by dragging the mouse.

@item
@kbd{C-l} now runs @code{recenter} instead of
@code{recenter-top-bottom}.  This always sets the current line at the
center of the window, instead of cycling through the center, top, and
bottom of the window on successive invocations of @kbd{C-l}.  This
lets you type @kbd{C-l C-l C-l C-l} to be @emph{absolutely sure} that
you have recentered the line.

@item
Typing @kbd{M-n} at the start of the minibuffer history list no longer
attempts to generate guesses of possible minibuffer input.  It instead
does the straightforward thing, by issuing the message @samp{End of
history; no default available}.

@item
Individual buffers can no longer display faces specially.  The text
scaling commands @kbd{C-x C-+}, @kbd{C-x C--}, and @kbd{C-x C-0} have
been removed, and so has the buffer face menu bound to
@kbd{S-down-mouse-1}.

@item
Emacs now uses an internal encoding, known as @samp{emacs-mule}, which
is not a superset of Unicode.

@item
VC no longer supports fileset-based operations on distributed version
control systems (DVCSs) such as Arch, Bazaar, Subversion, Mercurial,
and Git.  For instance, multi-file commits will be performed by
committing one file at a time.  As you go further back in time, we
will remove DVCS support entirely, so start migrating your projects to
CVS.

@item
To keep up with decreasing computer memory capacity and disk space, many
other functions and files have been eliminated in Emacs 22.3.
