Emacs 21.3 Antinews
*******************

For those users who live backwards in time, here is information about downgrading to Emacs version 21.3.  We hope you will enjoy the greater simplicity that results from the absence of many newer features.

  * The input methods for Emacs are included in a separate distribution called ``Leim''.  To use them, you must extract the Leim tar file on top of the Emacs distribution, into the same directory, before you build Emacs.

  * The file position and line number information is now at the end of the mode line.

  * When a file is managed with version control, the command C-x C-q (whose general meaning is to make a buffer read-only or writable) now does so by checking the file in or out.  Checking the file out makes the buffer writable; checking it in makes the buffer read-only (at least with RCS).

     You can still use C-x v v to do these operations if you wish; its meaning is unchanged.  If you want to control the buffer's read-only flag without performing any version control operation, use M-x toggle-read-only.

  * Filesets are not supported.

  * For simplicity, windows always have fringes.  We wouldn't want to in-fringe anyone's windows.  Likewise, horizontal scrolling always works the same automatic way.

  * When you are logged in as root, all files now give you writable buffers in Emacs reflecting the fact that you can write any files.

  * Unicode support and unification between Latin-N character sets have been removed.  Cutting and pasting X selections does not support ``extended segments'' so there are certain coding systems it cannot handle.

  * C-w in an incremental search always grabs an entire word into the search string.  More precisely, it grabs text through the next end of a word.

  * Yanking now preserves all text properties that were in the killed text.  The variable yank-excluded-properties has no meaning.

  * Occur mode, Info mode, and Comint-derived modes now control fontification in their own way, and M-x font-lock-mode has nothing to do with it.  To control fontification in Info mode, use the variable Info-fontify.

  * In Dired's ! command, * and ? now cause substitution of the file names wherever they appear---not only when they are surrounded by whitespace.

  * Minibuffer completion commands now always complete the entire minibuffer contents, just as if you had typed them at the end of the minibuffer, no matter where point is actually located.

  * An unquoted $ in a file name is now an error, if the following name is not recognized as an environment variable.  Thus, the file name foo$bar would probably be an error.  Meanwhile, the setenv command does not expand $ at all.

  * Commands to set the mark at a place away from point, including M-@, M-h, etc., don't do anything special when you repeat them.  In most cases, typing these commands multiple times is equivalent to using them once.  M-h does not use its numeric argument.

  * C-SPC C-SPC has no special meaning and neither does C-u C-x C-x.

  * There is no horizontal-bar cursor.

  * The faces minibuffer-prompt and mode-line-inactive do not exist, and the features they control don't exist either.

  * The default value of keyboard-coding-system is always nil. Emacs does not set it based on your locale settings. If you want some other value, you must set it yourself.

  * SGML mode does not handle XML syntax, and does not have indentation support.

  * The C-h subcommands have been rearranged---especially those that display specific files.  Type C-h C-h to see a list of these commands; that will show you what is different.

  * Emacs does not read ~/.abbrev_defs automatically; if you want to load abbrev definitions from a file, you must always do so explicitly.

  * The --fullwidth, --fullheight and --fullscreen command line options are not supported.

  * The --geometry option now entirely applies only to the initial frame.

  * Many commands have been removed from the menus or rearranged.

  * Many etags features for customizing parsing using regexps have been removed.

  * The CUA, ido, table, tramp, reveal, ruler-mode, and ibuffer packages have been removed.  So has the spreadsheet, SES, and the algebraic calculator, Calc.  (We distribute Calc separately.)

  * The kmacro package has been removed.  To start a keyboard macro you must use C-x (; to end one, C-x ); to execute the last one, C-x e.

  * To keep up with decreasing computer memory capacity and disk space, many other functions and files have been eliminated in Emacs 21.3.
