@itemize @bullet
-
-@item
-The buffer position and line number are now displayed at the end of
-the mode line, where they can be more easily seen.
-
-@item
-The mode line of the selected window is no longer displayed with a
-special face. All mode lines are created equal. Meanwhile, you can
-use the variable @code{mode-line-inverse-video} to control whether
-mode lines are highlighted at all---@code{nil} means don't highlight
-them.
-
-@item
-Clicking on a link with the left mouse button (@kbd{mouse-1}) will
-always set point at the position clicked, instead of following the
-link. If you want to follow the link, use the middle mouse button
-(@kbd{mouse-2}).
-
-@item
-Emacs is tired of X droppings. If you drop a file or a piece of text
-onto an Emacs window, nothing will happen.
-
-@item
-On an xterm, even if you enable Xterm Mouse mode, Emacs provides a
-more convincing simulation of a text terminal by not responding to
-mouse clicks on the mode line, header line, or display margin.
-
-@item
-For simplicity, windows always have fringes. We wouldn't want to
-in-fringe anyone's windows. Likewise, horizontal scrolling always
-works in the same automatic way.
-
-@item
-The horizontal-bar cursor shape has been removed.
-
-@item
-If command line arguments are given, Emacs will not display a splash
-screen, so that you can immediately get on with your editing. The
-command-line option @samp{--no-splash} is therefore obsolete, and has
-been removed.
-
-@item
-These command line options have also been removed: @samp{--color},
-@samp{--fullwidth}, @samp{--fullheight}, @samp{--fullscreen},
-@samp{--no-blinking-cursor}, @samp{--no-desktop}, and @samp{-Q}.
-
-@item
-The @samp{--geometry} option applies only to the initial frame, and
-the @samp{-f} option will not read arguments for interactive
-functions.
-
-@item
-We have standardized on one location for the user init file: the file
-named @file{.emacs} in your home directory. Emacs will not look for
-the init file in @file{~/.emacs.d/init.el}. Similarly, don't try
-putting @file{.emacs_SHELL} as @file{init_SHELL.sh} in
-@file{~/.emacs.d}; Emacs won't find it.
-
-@item
-Emacs will not read @file{~/.abbrev_defs} automatically. If you want
-to load abbrev definitions from a file, you must always do so
-explicitly.
-
-@item
-When you are logged in as root, all files now give you writable
-buffers, reflecting the fact that you can write any files.
-
-@item
-The maximum size of buffers and integer variables has been halved. On
-32-bit machines, the maximum buffer size is now 128 megabytes.
-
-@item
-An unquoted @samp{$} in a file name is now an error, if the following
-name is not recognized as an environment variable. Thus,
-the file name @file{foo$bar} would probably be an error. Meanwhile,
-the @code{setenv} command does not expand @samp{$} at all.
-
-@item
-If a single command accumulates too much undo information, Emacs never
-discards it. If Emacs runs out of memory as a result, it will handle
-this by crashing.
-
-@item
-Many commands have been removed from the menus or rearranged.
-
-@item
-The @kbd{C-h} (help) subcommands have been rearranged---especially
-those that display specific files. Type @kbd{C-h C-h} to see a list
-of these commands; that will show you what is different.
-
-@item
-The @kbd{C-h v} and @kbd{C-h f} commands no longer show a hyperlink to
-the C source code, even if it is available. If you want to find the
-source code, grep for it.
-
-@item
-The apropos commands will not accept a list of words to match, in
-order to encourage you to be more specific. Also, the user option
-@code{apropos-sort-by-scores} has been removed.
-
-@item
-The minibuffer prompt is now displayed using the default face.
-The colon is enough to show you what part is the prompt.
-
@item
-Minibuffer completion commands 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.
+Support for displaying and editing ``bidirectional'' text has been
+removed. Text is now always displayed on the screen in a single
+consistent direction---left to right---regardless of the underlying
+script. Similarly, @kbd{C-f} and @kbd{C-b} always move the text
+cursor to the right and left respectively. Also, @key{right} and
+@key{left} are now equivalent to @kbd{C-f} and @kbd{C-b}, as you might
+expect, rather than moving forward or backward based on the underlying
+``paragraph direction''.
-@item
-The command @code{backward-kill-sexp} is now bound to @kbd{C-M-delete}
-and @kbd{C-M-backspace}. Be careful when using these key sequences!
-It may shut down your X server, or reboot your operating system.
-
-@item
-Commands to set the mark at a place away from point, including
-@kbd{M-@@}, @kbd{M-h}, etc., don't do anything special when you repeat
-them. In most cases, typing these commands multiple times is
-equivalent to typing them once. @kbd{M-h} ignores numeric arguments.
-
-@item
-The user option @code{set-mark-command-repeat-pop} has been removed.
-
-@item
-@kbd{C-@key{SPC} C-@key{SPC}} has no special meaning--it just sets the
-mark twice. Neither does @kbd{C-u C-x C-x}, which simply exchanges
-point and mark like @kbd{C-x C-x}.
-
-@item
-The function @code{sentence-end} has been eliminated in favor of a
-more straightforward approach: directly setting the variable
-@code{sentence-end}. For example, to end each sentence with a single
-space, use
-
-@lisp
-(setq sentence-end "[.?!][]\"')@}]*\\($\\|[ \t]\\)[ \t\n]*")
-@end lisp
-
-@item
-The variable @code{fill-nobreak-predicate} is no longer customizable,
-and it can only hold a single function.
-
-@item
-Nobreak spaces and hyphens are displayed just like normal characters,
-and the user option @code{nobreak-char-display} has been removed.
-
-@item
-@kbd{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.
-
-@item
-Yanking now preserves all text properties that were in the killed
-text. The variable @code{yank-excluded-properties} has been removed.
-
-@item
-Occur mode, Info mode, and Comint-derived modes now control
-fontification in their own way, and @kbd{M-x font-lock-mode} has
-nothing to do with it. To control fontification in Info mode, use the
-variable @code{Info-fontify}.
-
-@item
-@samp{M-x shell} is now completely standard in regard to scrolling
-behavior. It no longer has the option of scrolling the input line to
-the bottom of the window the way a text terminal running a shell does.
+Users of ``right-to-left'' languages, like Arabic and Hebrew, may
+adapt by reading and/or editing text in left-to-right order.
@item
-The Grep package has been merged with Compilation mode. Many
-grep-specific commands and user options have thus been eliminated.
-Also, @kbd{M-x grep} never tries the GNU grep @samp{-H} option,
-and instead silently appends @file{/dev/null} to the command line.
+The Emacs Lisp package manager has been removed. Instead of using a
+``user interface'' (@kbd{M-x list-packages}), additional Lisp packages
+must now be installed by hand, which is the most flexible and
+``Lispy'' method anyway. Typically, this just involves editing your
+init file to add the package installation directory to the load path
+and defining some autoloads; see each package's commentary section
+and/or README file for details.
@item
-In Dired's @kbd{!} command, @samp{*} and @samp{?} now
-cause substitution of the file names wherever they appear---not
-only when they are surrounded by whitespace.
+The option @code{delete-active-region} has been deleted. When the
+region is active, typing @key{DEL} or @key{delete} no longer deletes
+the text in the region; it deletes a single character instead.
@item
-When a file is managed with version control, the command @kbd{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.
+We have reworked how Emacs handles the clipboard and the X primary
+selection. Commands for killing and yanking, like @kbd{C-w} and
+@kbd{C-y}, use the primary selection and not the clipboard, so you can
+use these commands without interfering with ``cutting'' or ``pasting''
+in other programs. The @samp{Cut}/@samp{Copy}/@samp{Paste} menu items
+are bound to separate clipboard commands, not to the same commands as
+@kbd{C-w}/@kbd{M-w}/@kbd{C-y}.
-You can still use @kbd{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 @kbd{M-x toggle-read-only}.
+Selecting text by dragging with the mouse now puts the text in the
+kill ring, in addition to the primary selection. But note that
+selecting an active region with @kbd{C-@key{SPC}} does @emph{not}
+alter the kill ring nor the primary selection, even though the text
+highlighting is visually identical.
@item
-SGML mode does not handle XML syntax, and does not have indentation
-support.
+In Isearch, @kbd{C-y} and @kbd{M-y} are no longer bound to
+@code{isearch-yank-kill} and @code{isearch-yank-pop} respectively.
+Instead, @kbd{C-y} yanks the rest of the current line into the search
+string (@code{isearch-yank-line}), whereas @kbd{M-y} does
+@code{isearch-yank-kill}. The mismatch with the usual meanings of
+@kbd{C-y} and @kbd{M-y} is unintended.
@item
-Many Info mode commands have been removed. Incremental search in Info
-searches only the current node.
+Various completion features have been simplified. The options
+@code{completion-cycle-threshold} and
+@code{completion-category-overrides} have been removed. Due to the
+latter removal, Emacs uses a single consistent scheme to generate
+completions, instead of using a separate scheme for (say) buffer name
+completion. Several major modes, such as Shell mode, now implement
+their own inline completion commands instead of using
+@code{completion-at-point}.
@item
-Many @code{etags} features for customizing parsing using regexps
-have been removed.
+We have removed various options for controlling how windows are used,
+e.g.@: @code{display-buffer-base-action}, @code{display-buffer-alist},
+@code{window-combination-limit}, and @code{window-combination-resize}.
@item
-The Emacs server now runs a small C program called @file{emacsserver},
-rather than trying to handle everything in Emacs Lisp. Now there can
-only be one Emacs server running at a time. The @code{server-mode}
-command and @code{server-name} user option have been eliminated.
+The command @kbd{M-x customize-themes} has been removed. Emacs no
+longer comes with pre-defined themes (you can write your own).
@item
-The @file{emacsclient} program no longer accepts the @samp{--eval},
-@samp{--display} and @samp{--server-file} command line options, and
-can only establish local connections using Unix domain sockets.
+Emacs no longer adapts various aspects of its display to GTK+
+settings, opting instead for a uniform toolkit-independent look. GTK+
+scroll bars are placed on the left, the same position as non-GTK+ X
+scroll bars. Emacs no longer refers to GTK+ to set the default
+@code{region} face, nor for drawing tooltips.
@item
-The command @code{quail-show-key}, for showing how to input a
-character, has been removed.
+Setting the option @code{delete-by-moving-to-trash} to a
+non-@code{nil} now causes all file deletions to use the system trash,
+even temporary files created by Lisp programs; furthermore, the
+@kbd{M-x delete-file} and @kbd{M-x delete-directory} commands no
+longer accept prefix arguments to force true deletion.
@item
-The default value of @code{keyboard-coding-system} is always
-@code{nil}, regardless of your locale settings. If you want some
-other value, set it yourself.
+On GNU/Linux and Unix, the default method for sending mail (as
+specified by @code{send-mail-function}) is to use the
+@command{sendmail} program. Emacs no longer asks for a delivery
+method the first time you try to send mail, trusting instead that the
+system is configured for mail delivery, as it ought to be.
@item
-Unicode support and unification between Latin-@var{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.
-
-@item
-The input methods for Emacs are included in a separate distribution
-called ``Leim.'' To use this, you must extract the Leim tar file on
-top of the Emacs distribution, into the same directory, before you
-build Emacs.
-
-@item
-The following input methods have been eliminated: belarusian,
-bulgarian-bds, bulgarian-phonetic, chinese-sisheng, croatian, dutch,
-georgian, latin-alt-postfix, latin-postfix, latin-prefix,
-latvian-keyboard, lithuanian-numeric, lithuanian-keyboard,
-malayalam-inscript, rfc1345, russian-computer, sgml, slovenian,
-tamil-inscript ucs, ukrainian-computer, vietnamese-telex, and welsh.
-
-@item
-The following language environments have been eliminated: Belarusian,
-Bulgarian, Chinese-EUC-TW, Croatian, French, Georgian, Italian,
-Latin-6, Latin-7, Latvian, Lithuanian, Malayalam, Russian, Russian,
-Slovenian, Swedish, Tajik, Tamil, UTF-8, Ukrainian, Ukrainian, Welsh,
-and Windows-1255.
-
-@item
-The @code{code-pages} library, which contained various 8-bit coding
-systems, has been removed.
-
-@item
-The Kmacro package has been replaced with a simple and elegant
-keyboard macro system. Use @kbd{C-x (} to start a new keyboard macro,
-@kbd{C-x )} to end the macro, and @kbd{C-x e} to execute the last
-macro. Use @kbd{M-x name-last-kbd-macro} to name the most recently
-defined macro.
-
-@item
-Emacs no longer displays your breakpoints in the source buffer, so you
-have to remember where you left them. It can be difficult to inspect
-the state of your debugged program from the command line, so Emacs
-tries to demonstrate this in the GUD buffer.
-
-@item
-The Calc, CUA, Ibuffer, Ido, Password, Printing, Reveal,
-Ruler-mode, SES, Table, Tramp, and URL packages have been removed.
-The Benchmark, Cfengine, Conf, Dns, Flymake, Python, Thumbs, and
-Wdired modes have also been removed.
-
-@item
-The Emacs Lisp Reference Manual and the Introduction to Programming in
-Emacs Lisp are now distributed separately, not in the Emacs
-distribution.
-
-@item
-On MS Windows, there is no longer any support for tooltips, images,
-sound, different mouse pointer shapes, or pointing devices with more
-than 3 buttons. If you want these features, consider switching to
-another operating system. But even if you don't want these features,
-you should still switch---for freedom's sake.
-
-@item
-Emacs will not use Unicode for clipboard operations on MS Windows.
+Several VC features have been removed, including the @kbd{C-x v +} and
+@kbd{C-x v m} commands for pulling and merging on distributed version
+control systems, and the ability to view inline log entries in the log
+buffers made by @kbd{C-x v L}.
@item
To keep up with decreasing computer memory capacity and disk space, many
-other functions and files have been eliminated in Emacs 21.4.
