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

  16 The Fontconfig font library is no longer supported.  To specify a
  17 font, you must use an XLFD (X Logical Font Descriptor).  The other
  18 ways of specifying fonts---so-called ``Fontconfig'' and ``GTK'' font
  19 names---are clearly redundant, and have been removed.
  20
  21 @item
  22 Emacs no longer performs font anti-aliasing.  If your fonts look ugly,
  23 try choosing a larger font and increasing the screen resolution.  This
  24 may admittedly become difficult as you go further back in time, since
  25 available screen resolutions will decrease.
  26
  27 @item
  28 Emacs has added support for some soon-to-be-non-obsolete platforms.
  29 These include GNU/Linux systems based on libc version 5, BSD systems
  30 based on the COFF executable format, Solaris versions less than 2.6,
  31 and many more.
  32
  33 @item
  34 Emacs can no longer display frames on X windows and text terminals
  35 (ttys) simultaneously.  If you start Emacs as an X application, the
  36 Emacs job can only create X frames; if you start Emacs on a tty, the
  37 Emacs job can only use that tty.
  38
  39 @item
  40 Emacs can no longer be started as a daemon.
  41
  42 @item
  43 Transient Mark mode is now disabled by default.  Furthermore, some
  44 commands that operate specifically on the region when it is active and
  45 Transient Mark mode is enabled (such as @code{fill-paragraph}
  46 @code{ispell-word}, and @code{indent-for-tab-command}), no longer do
  47 so.
  48
  49 @item
  50 The line motion commands, @kbd{C-n} and @kbd{C-p}, now move by logical
  51 text lines, not screen lines.  Even if a long text line is continued
  52 over multiple screen lines, @kbd{C-n} and @kbd{C-p} treat it as a
  53 single line, because that's ultimately what it is.
  54
  55 @item
  56 Visual Line mode, which provides ``word wrap'' functionality, has been
  57 removed.  You can still use Long Lines mode to gain an approximation
  58 of word wrapping, though this has some drawbacks---for instance,
  59 syntax highlighting often doesn't work well on wrapped lines.
  60
  61 @item
  62 The variable @code{shift-select-mode} has been deleted; holding
  63 @key{shift} while typing a motion command no longer creates a
  64 temporarily active region.  You can still create temporarily active
  65 regions by dragging the mouse.
  66
  67 @item
  68 @kbd{C-l} now runs @code{recenter} instead of
  69 @code{recenter-top-bottom}.  This always sets the current line at the
  70 center of the window, instead of cycling through the center, top, and
  71 bottom of the window on successive invocations of @kbd{C-l}.  This
  72 lets you type @kbd{C-l C-l C-l C-l} to be @emph{absolutely sure} that
  73 you have recentered the line.
  74
  75 @item
  76 Typing @kbd{M-n} at the start of the minibuffer history list no longer
  77 attempts to generate guesses of possible minibuffer input.  It instead
  78 does the straightforward thing, by issuing the message @samp{End of
  79 history; no default available}.
  80
  81 @item
  82 Individual buffers can no longer display faces specially.  The text
  83 scaling commands @kbd{C-x C-+}, @kbd{C-x C--}, and @kbd{C-x C-0} have
  84 been removed, and so has the buffer face menu bound to
  85 @kbd{S-down-mouse-1}.
  86
  87 @item
  88 Emacs now uses an internal encoding, known as @samp{emacs-mule}, which
  89 is not a superset of Unicode.
  90
  91 @item
  92 VC no longer supports fileset-based operations on distributed version
  93 control systems (DVCSs) such as Arch, Bazaar, Subversion, Mercurial,
  94 and Git.  For instance, multi-file commits will be performed by
  95 committing one file at a time.  As you go further back in time, we
  96 will remove DVCS support entirely, so start migrating your projects to
  97 CVS.
  98
  99 @item
 100 To keep up with decreasing computer memory capacity and disk space, many
 101 other functions and files have been eliminated in Emacs 22.3.
