-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.
+We have switched to a character representation specially designed for
+Emacs. Rather than forcing all the widely used scripts into artificial
+alignment, as Unicode does, Emacs treats them all equally, giving
+each one a place in the space of character codes. We have eliminated
+the confusing practice, in Emacs 23, whereby one character can belong
+to multiple character sets. Now each script has its own variant, and
+they all are different as far as Emacs is concerned. For example,
+there's a Latin-1 c-cedilla character, and there's a Latin-2
+c-cedilla; searching a buffer for the Latin-1 variant only finds that
+variant, but not the others.
@item
-Emacs no longer performs font anti-aliasing. If your fonts look ugly,
-try choosing a larger font and increasing the screen resolution.
-Admittedly, this becomes difficult as you go further back in time,
-since available screen resolutions will decrease.
+Emacs now uses its own special internal encoding for non-@acronym{ASCII}
+characters, known as @samp{emacs-mule}. This was imperative to
+support several different variants of the same character, each one
+belonging to its own script: @samp{emacs-mule} marks each character
+with its script, to better discern them from one another.
@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.
+For simplicity, the functions @code{encode-coding-region} and
+@code{decode-coding-region} no longer accept an argument saying where
+to store the result of their conversions. The result always replaces
+the original, so there's no need to look for it elsewhere.
@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.

Transient Mark mode is now disabled by default. Furthermore, some
@code{ispell-word}, and @code{indent-for-tab-command}), no longer do
so.

+Holding @key{shift} while typing a motion command no longer creates a
+temporarily active region, since that's inconsistent with how Emacs
+normally handles keybindings. The variable @code{shift-select-mode}
+has been deleted. You can, however, still create temporarily active
+regions by dragging the mouse.

@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
of word wrapping, though this has some drawbacks---for instance,
syntax highlighting often doesn't work well on wrapped lines.

@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.

+The way Emacs generates possible minibuffer completions is now much
+simpler to understand. It matches alternatives to the text before
+point, ignoring the text after point; it also does not attempt to
+perform partial completion if the first completion attempt fails.
@item
Typing @kbd{M-n} at the start of the minibuffer history list no longer
been removed, and so has the buffer face menu bound to
@kbd{S-down-mouse-1}.

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.

+Rmail now uses a special file format, Babyl format, specifically designed

+mail, Rmail converts it automatically to Babyl format.

+Emacs can no longer display frames on X windows and text terminals

+Emacs has added support for many soon-to-be-non-obsolete platforms,
