+* Changes in XEmacs 20.4
+========================
+** XEmacs 20.4 is a bugfix release with no user-visible changes.
+* Changes in XEmacs 20.3
+========================
+** Quail input method is now available.
+Quail is a simple key-translation system that allows users to input
+any multilingual text from normal ASCII keyboard.  This means that
+XEmacs with Mule now supports a number of European languages.
+** More Windows NT support.
+Thanks to efforts of many people, coordinated by David Hobley
+<davidh@wr.com.au> and Marc Paquette <marcpa@cam.org>, beta versions
+of XEmacs now run on 32-bit Windows platforms (Windows NT and Windows
+95).  The current betas require having an X server to run XEmacs;
+however, a native NT/95 port is in alpha, thanks to Jonathan Harris
+<jhar@tardis.ed.ac.uk>.
+The NT development is now coordinated by a mailing list at
+<xemacs-nt@xemacs.org>.  Mail to <xemacs-nt-request@xemacs.org> to
+subscribe.
+** Multiple TTY frames are now available.
+On consoles that display only one frame at a time (e.g. TTY consoles),
+creating a new frame with `C-x 5 2' also raises and selects that
+frame.  The behavior of window system frames is unchanged.
+** Package starting changes.
+State of Emacs should never be changed with loading a package.  The
+following XEmacs packages that used to break this have been changed.
+*** Loading `paren' no longer enables paren-blinking.  Use
+`paren-set-mode' explicitly, or customize `paren-mode'.
+*** Loading `uniquify' no longer enables uniquify.  Set
+`uniquify-buffer-name-style' to a legal value.
+*** Loading `time' no longer enables display time.  Invoke
+`display-time' explicitly.
+*** Loading `jka-compr' no longer enables on-the-fly compression.  Use
+`toggle-auto-compression' instead.
+*** Loading `id-select' no longer enables its behaviour.  Use
+`id-select-install' instead.
+** Zmacs region is not deactivated when an error is signaled.
+The behavior of the zmacs region can now be controlled in the event of
+a signaled error.  The new variable `errors-deactivate-region' may be
+set to nil to revert to the old behaviour.  As before, typing C-g
+deactivates the region.
+** Multiple Info `dir' functionality has been merged with GNU Emacs
+19.34.
+XEmacs will now correctly merge all the `dir' files in
+`Info-directory-list' (initialized from either the `INFOPATH'
+env. variable or `Info-default-directory-list'.)  These files may be
+full-fledged info files containing subnodes or menus.  Previously
+supported `localdir' files are looked for also, secondary to `dir's.
+See the manual for details.
+** Abbreviations can now contain non-word characters.
+This means that it is finally possible to do such simple things as
+define `#in' to expand to `#include' in C mode, `s-c-b' to
+`save-current-buffer' in Lisp mode, `call/cc' to
+`call-with-current-continuation' in Scheme mode, etc.
+** `C-x n d' now runs the new command `narrow-to-defun',
+which narrows the accessible parts of the buffer to just
+the current defun.
+** The new command `C-x 4 0' (kill-buffer-and-window) kills the
+current buffer and deletes the selected window.  It asks for
+confirmation first.
+** `ESC ESC ESC' (keyboard-escape-quit) will now correctly abort
+recursive edits (as documented.)
+** arc-mode has a new function called `archive-quit' bound to q, which
+quits archive mode in the same fashion dired-quit works.
+** A `tetris' clone is now available within XEmacs, written by Glynn
+Clements.  Try it out with `M-x tetris'.
+** The feature to teach the key bindings of extended commands now
+prints the message after the command finishes.  After some time, the
+previous echo area contents are restored (in case the command prints
+something useful).
+** If you set scroll-conservatively to a small number, then when you
+move point a short distance off the screen, XEmacs will scroll the
+screen just far enough to bring point back on screen, provided that
+does not exceed `scroll-conservatively' lines.
+** Face background colors now take precedence over the default face
+background pixmap, which means that background pixmaps no longer clash
+with zmacs-regions, or clickable buttons.
+** Regexps can now contain additional Perl-like constructs.
+** Modifiers can be added to a keystroke by preceding it with a `C-x @
+<x>' sequence where <x> is one of letters `S', `c', `m', `a', `h', `s'
+corresponding to shift, control, meta, alt, hyper, and super modifiers,
+respectively.  It is possible to add several modifiers by repeating this
+sequence.  This feature is especially useful on text terminals where it
+allows one to enter keystrokes like, e.g., `M-home'.
+** An arbitrary keystroke can be generated by entering `C-x @ k
+<keysym-name> RET'.  For example a sequence:
+C-x @ c C-x @ k b a c k s p a c e RET
+will result in a `C-backspace' keystroke even on text terminals.
+** Customize changes.
+*** Customize has undergone a massive speedup, and should now operate
+acceptably fast.  Slowness of the interface used to be the biggest
+gripe.
+*** Many more packages have been modified to use the facility, so
+almost all of XEmacs options can now be examined through the Customize
+groups.
+*** There is a new `browser' mode of traversing customizations, in
+many ways easier to follow than the standard one.  Try it out with
+`M-x customize-browse'.
+** Pending-delete changes.
+*** Pending-delete is now a minor mode, with the normal minor-mode
+semantics and toggle functions.  Old functions are left for
+compatibility.
+*** Loading pending-del no longer turns on pending-delete mode.  In
+fact, it is no longer necessary to explicitly load pending-del.  All
+you need to do to turn on pending-delete is run the pending-delete
+function:
+Within XEmacs:   Type      M-x pending-delete <ret>
+not      M-x load-library <ret> pending-delete <ret>
+In .emacs:       Use       (turn-on-pending-delete)
+not       (load "pending-del")
+** XEmacs can now save the minibuffer histories from various
+minibuffers.  To use this feature, add the line:
+(savehist-load)
+to your .emacs.  This will load the minibuffer histories (if any) at
+startup, as well as instruct XEmacs to save them before exiting.  You
+can use Customize to add or remove the histories being saved.
+** The default format for ChangeLog entries (as created by `C-x 4 a')
+is now the international ISO 8601 format.
+To revert to the old behaviour, use:
+(setq add-log-time-format 'current-time-string)
+Or `M-x customize RET add-log RET'.
+** In ChangeLog mode, you can now press `C-c C-c' to save the file
+and restore old window configuration, or `C-c C-k' to abandon the
+changes.
+** The key `C-x m' no longer runs the `mail' command directly.
+Instead, it runs the command `compose-mail', which invokes the mail
+composition mechanism you have selected with the variable
+`mail-user-agent'.  The default choice of user agent is
+`sendmail-user-agent', which gives behavior compatible with the old
+behavior.
+C-x 4 m now runs compose-mail-other-window, and C-x 5 m runs
+compose-mail-other-frame.
+** When you kill a buffer that visits a file, if there are any
+registers that save positions in the file, these register values no
+longer become completely useless.  If you try to go to such a register
+with `C-x j', then you are asked whether to visit the file again.  If
+you say yes, it visits the file and then goes to the same position.
+** When you visit a file that changes frequently outside Emacs--for
+example, a log of output from a process that continues to run--it may
+be useful for Emacs to revert the file without querying you whenever
+you visit the file afresh with `C-x C-f'.
+You can request this behavior for certain files by setting the
+variable revert-without-query to a list of regular expressions.  If a
+file's name matches any of these regular expressions, find-file and
+revert-buffer revert the buffer without asking for permission--but
+only if you have not edited the buffer text yourself.
+** Gnuserv changes
+*** The Lisp part of gnuserv has been rewritten to allow for more
+flexibility and features.
+*** Many new options and variables are now customizable.  Try
+`M-x customize RET gnuserv RET'.
+*** The functionality of `gnuattach' and `gnudoit' programs is
+provided by `gnuclient', which now accepts the standard `-nw',
+`-display', `-eval' and `-f' options.
+** Etags changes.
+*** In C, C++, Objective C and Java, Etags tags global variables by
+default.  The resulting tags files are inflated by 30% on average.
+Use --no-globals to turn this feature off.  Etags can also tag
+variables that are members of structure-like constructs, but it does
+not by default.  Use --members to turn this feature on.
+*** C++ member functions are now recognized as tags.
+*** Java is tagged like C++.  In addition, "extends" and "implements"
+constructs are tagged.  Files are recognised by the extension .java.
+*** Etags can now handle programs written in Postscript.  Files are
+recognised by the extensions .ps and .pdb (Postscript with C syntax).
+In Postscript, tags are lines that start with a slash.
+*** Etags now handles Objective C and Objective C++ code.  The usual C and
+C++ tags are recognized in these languages; in addition, etags
+recognizes special Objective C syntax for classes, class categories,
+methods and protocols.
+*** Etags also handles Cobol.  Files are recognised by the extension
+.cobol.  The tagged lines are those containing a word that begins in
+column 8 and ends in a full stop, i.e. anything that could be a
+paragraph name.
+*** Regexps in Etags now support intervals, as in ed or grep.  The syntax of
+an interval is \{M,N\}, and it means to match the preceding expression
+at least M times and as many as N times.
+** Ada mode changes.
+*** There is now better support for using find-file.el with Ada mode.
+If you switch between spec and body, the cursor stays in the same
+procedure (modulo overloading).  If a spec has no body file yet, but
+you try to switch to its body file, Ada mode now generates procedure
+stubs.
+*** There are two new commands:
+- `ada-make-local'   : invokes gnatmake on the current buffer
+- `ada-check-syntax' : check syntax of current buffer.
+The user options `ada-compiler-make', `ada-make-options',
+`ada-language-version', `ada-compiler-syntax-check', and
+`ada-compile-options' are used within these commands.
+*** Ada mode can now work with Outline minor mode.  The outline level
+is calculated from the indenting, not from syntactic constructs.
+Outlining does not work if your code is not correctly indented.
+*** The new function `ada-gnat-style' converts the buffer to the style of
+formatting used in GNAT.  It places two blanks after a comment start,
+places one blank between a word end and an opening '(', and puts one
+space between a comma and the beginning of a word.
+** New demand based locking implementation
+A faster, but experimental replacement for lazy-lock (called lazy-shot) is
+provided.  Like lazy-lock it provides demand based and idle time
+font-lock-ing.  However the lazy-lock versions that came with previous
+versions slowed down XEmacs (possibly quite a lot).  Lazy-shot solves
+this problem by relying on new support from the C code part of XEmacs.
+The support however is experimental and will cause some flashing as
+parts of the buffer are colored.  This likely to change in the future
+as the C support is completed.
+The current lazy-shot implementation is mostly interface compatible
+with lazy-lock v2.06 (the version shipped with XEmacs is v1.x).
+*** To enable:
+1. Despite the flashing, lazy-shot was deemed such an improvement by
+the majority of beta testers that it is now the standard method
+provided by the options menu. Alternatively add
+	(add-hook 'font-lock-mode-hook 'turn-on-lazy-shot)
+to '.emacs'.
+2. If you were using lazy-lock before, just replace all occurrences of
+"lazy-lock" by "lazy-shot" in your '.emacs' file.
+*** To disable:
+If prefer to use lazy-lock in stead of lazy-shot, put
+	(remove-hook 'font-lock-mode-hook 'turn-on-lazy-shot)
+	(add-hook 'font-lock-mode-hook 'turn-on-lazy-lock)
+at the END of `.emacs'.
+** RefTeX mode
+RefTeX mode is a new minor mode with special support for \label{}, \ref{}
+and \cite{} macros in LaTeX documents.  RefTeX distinguishes labels of
+different environments (equation, figure, ...) and has full support for
+multifile documents.  To use it, select a buffer with a LaTeX document and
+turn the mode on with M-x reftex-mode.  Here are the main user commands:
+C-c (    reftex-label
+Creates a label semi-automatically.  RefTeX is context sensitive and
+knows which kind of label is needed.
+C-c )    reftex-reference
+Offers in a menu all labels in the document, along with context of the
+label definition.  The selected label is referenced as \ref{LABEL}.
+C-c [    reftex-citation
+Prompts for a regular expression and displays a list of matching BibTeX
+database entries.  The selected entry is cited with a \cite{KEY} macro.
+C-c &    reftex-view-crossref
+Views the cross reference of a \ref{} or \cite{} command near point.
+C-c =    reftex-toc
+Shows a table of contents of the (multifile) document.  From there you
+can quickly jump to every section.
+Under X, RefTeX installs a "Ref" menu in the menu bar, with additional
+commands.  Full documentation and customization examples are in the file
+reftex.el.  You can use the finder to view this information:
+C-h p --> tex --> reftex.el
+* Lisp and internal changes in XEmacs 20.3
+==========================================
+** Autoconf 2 is supported, making XEmacs more conforming to
+conventions used by other free software.
+** `tty-erase-char' is a new variable that reports which character
+was set up as the terminal's erase character at the time Emacs was
+started.
+** It is now possible to attach the menubar accelerator keys to menu
+entries.  Look at the Lispref under Menus->Menu Accelerators for
+details.
+** `insert-file-contents' can now read from a special file,
+as long as the arguments VISIT and REPLACE are nil.
+** `string-to-number' now accepts an optional BASE argument that
+specifies which base to use.  The default base is 10.
+** The TIME argument to `format-time-string' is now optional and
+defaults to the current time.
+** The PATTERN argument to `split-string' is now optional and defaults
+to whitespace ("[ \f\t\n\r\v]+").
+** `set-extent-properties' is a new function that can be used to
+change properties of an extent at once, and is analogous to
+`set-frame-properties'.
+** If a format field width is specified as `*', the field width is
+now assumed to have been specified as an argument (as in C.)
+(format "%*s" 10 "abc")
+=> "       abc"
+** The new macro `with-current-buffer' lets you evaluate an expression
+conveniently with a different current buffer.  It looks like this:
+(with-current-buffer BUFFER BODY-FORMS...)
+BUFFER is the expression that says which buffer to use.
+BODY-FORMS say what to do in that buffer.
+The old `eval-in-buffer' macro is obsoleted by `with-current-buffer'.
+** The new primitive `save-current-buffer' saves and restores the
+choice of current buffer, like `save-excursion', but without saving or
+restoring the value of point or the mark.  `with-current-buffer'
+works using `save-current-buffer'.
+** The new macro `with-temp-file' lets you do some work in a new buffer and
+write the output to a specified file.  Like `progn', it returns the value
+of the last form.
+** The variable `debug-ignored-errors' now works in XEmacs.  It allows
+one to ignore the debugger for some common errors, even when
+`debug-on-error' is t.  It has no effect when `debug-on-signal' is
+non-nil.
+** The new function `current-message' returns the message currently
+displayed in the echo area, or nil if there is none.
+** File-access primitive functions no longer discard an extra redundant
+directory name from the beginning of the file name.  In other words,
+they no longer do anything special with // or /~.  The same goes for
+`expand-file-name'.  That conversion is now done only in
+`substitute-in-file-name'.
+This makes it possible for a Lisp program to open a file whose name
+begins with ~.
+** The regexp matcher has been extended to recognize the following
+constructs, borrowed from Perl:
+*** Additional quantifiers.
+In addition to `*', `+' and `?', XEmacs now recognizes the following
+quantifiers:
+\{n\}    Match exactly n times
+\{n,\}   Match at least n times
+\{n,m\}  Match at least n but not more than m times
+*** Non-greedy quantifiers.
+Any of the standard quantifiers (`*', `+' and others) can now be
+followed by an optional `?', which will make them become "non-greedy",
+i.e. they will match as little text as possible.  Note that the
+meanings don't change, just the "gravity."
+*** Shy groups.
+The \(?: ... \) groups things like \( ... \), but doesn't record the
+context for backreferences or future use.  This is useful when you
+need a lot of groups for the sake of priorities, but actually want to
+record only one or two.
+** The new function `regexp-opt' returns an efficient regexp to match
+a string.  The arguments are STRINGS and (optionally) PAREN.  This
+function can be used where regexp matching or searching is intensively
+used and speed is important, e.g., in Font Lock mode.
+** The featurep syntax has been extended to resemble the Common Lisp
+one, as suggested by Erik Naggum.
+*** The `xemacs' feature is defined in XEmacs by default.
+*** The expression `#+fexp form' is equivalent to
+(when (featurep fexp) form), only it is evaluated at read-time.  Also,
+`#-fexp form' is equivalent to (unless (featurep fexp) form).
+*** In addition to symbols, a FEXP can also be a number, or a logical
+operator.  Here are some examples:
+;; evaluates to non-nil on XEmacs:
+(featurep 'xemacs)
+;; evaluates to non-nil on XEmacs 20.3 or later:
+(featurep '(and xemacs 20.03))
+;; evaluates to non-nil either on Emacs, or on XEmacs built without
+;; X support:
+(featurep '(or emacs (and xemacs (not x))))
+* Changes in XEmacs 20.2
+========================
+** Why XEmacs 20.1 is called 20.2
+Testing of XEmacs 20.1 revealed a number of showstopping bugs at the
+very final moment.  Instead of confusing the version numbers further,
+the `20.1' designation was abandoned, and the release was renamed to
+`20.2'.
+** Delete/backspace keysyms have been separated
+The Delete and Backspace keysyms are now no longer identical.  A better
+version of delbackspace.el has been added called delbs.el.
+** XEmacs 20.0 MULE API supported for backwards compatibility
+XEmacs 20.2 primarily supports the MULE 3 API.  It now also supports
+the XEmacs 20.0 MULE API.
+** The logo has been changed, and the default background color is
+now a shade of gray instead of the eye-burning white.
+The sample .Xdefaults and .emacs files contain examples of how to
+revert to the old background color.
+** Default modeline colors are now less of a color-salad.
+** The `C-z' key now iconifies only the current X frame.  You can use
+`C-x C-z' to get the old behavior.
+On the tty frames `C-z' behaves as before.
+** The command `display-time' now draws a pretty image in the modeline
+when new mail arrives.  It also supports balloon-help messages.
+** Various commands that were previously disabled are now enabled, like
+eval-expression (`M-:') and upcase-region (`C-x C-u')/downcase-region
+(`C-x C-l').
+** It is now possible to customize the functions called by XEmacs toolbar.
+Type `M-x customize RET toolbar RET' to customize it.  Customizations
+include the choice of functions for the buttons to invoke, as well as
+a wide choice of mailers and newsreaders to invoked by the respective
+functions.
+** `temp-buffer-shrink-to-fit' now defaults to nil.
+There are unresolved issues regarding this feature, which is why the
+XEmacs developers decided to disable it by default.
+** `ps-print-color-p' now defaults to nil.
+This is because the new default background color is non-white.  The
+`Printing Options' in the `Options' menu now include an item that
+enables color printing, and sets the white background.
+** `line-number-mode' should be used to get line numbers in the
+modeline, and `column-number-mode' to get column numbers.  Line
+numbers now number from 1 by default.
+** font-lock-mode will now correctly fontify `int a, b, c;'
+expressions in C mode.
+** The blinking cursor is always "on" during movement.
+** The XEmacs build process has been changed to make site
+administration easier.  See lisp/site-load.el for details.
+** Numerous causes of crashes have been fixed.  XEmacs should now be
+even more stable than before.
+** configure no longer defaults to using --with-xim=motif if Motif libraries
+are linked.
+There are many bugs in the Xlib XIM support in X11R6.3.
+** A number of new packages are added, and many packages were
+updated.
+** Gnus-5.4.52, courtesy of Lars Magne Ingebrigtsen
+*** nntp.el has been totally rewritten in an asynchronous fashion.
+*** Article prefetching functionality has been moved up into
+Gnus.
+*** Scoring can now be performed with logical operators like
+`and', `or', `not', and parent redirection.
+*** Article washing status can be displayed in the
+article mode line.
+*** gnus.el has been split into many smaller files.
+*** Suppression of duplicate articles based on Message-ID.
+(setq gnus-suppress-duplicates t)
+*** New variables for specifying what score and adapt files
+are to be considered home score and adapt files.  See
+`gnus-home-score-file' and `gnus-home-adapt-files'.
+*** Groups can inherit group parameters from parent topics.
+*** Article editing has been revamped and is now usable.
+*** Signatures can be recognized in more intelligent fashions.
+See `gnus-signature-separator' and `gnus-signature-limit'.
+*** Summary pick mode has been made to look more nn-like.
+Line numbers are displayed and the `.' command can be
+used to pick articles.
+*** Commands for moving the .newsrc.eld from one server to
+another have been added.
+`M-x gnus-change-server'
+*** A way to specify that "uninteresting" fields be suppressed when
+generating lines in buffers.
+*** Several commands in the group buffer can be undone with
+`M-C-_'.
+*** Scoring can be done on words using the new score type `w'.
+*** Adaptive scoring can be done on a Subject word-by-word basis:
+(setq gnus-use-adaptive-scoring '(word))
+*** Scores can be decayed.
+(setq gnus-decay-scores t)
+*** Scoring can be performed using a regexp on the Date header.  The
+Date is normalized to compact ISO 8601 format first.
+*** A new command has been added to remove all data on articles from
+the native server.
+`M-x gnus-group-clear-data-on-native-groups'
+*** A new command for reading collections of documents
+(nndoc with nnvirtual on top) has been added -- `M-C-d'.
+*** Process mark sets can be pushed and popped.
+*** A new mail-to-news backend makes it possible to post
+even when the NNTP server doesn't allow posting.
+*** A new backend for reading searches from Web search engines
+(DejaNews, Alta Vista, InReference) has been added.
+Use the `G w' command in the group buffer to create such
+a group.
+*** Groups inside topics can now be sorted using the standard
+sorting functions, and each topic can be sorted independently.
+See the commands under the `T S' submap.
+*** Subsets of the groups can be sorted independently.
+See the commands under the `G P' submap.
+*** Cached articles can be pulled into the groups.
+Use the `Y c' command.
+*** Score files are now applied in a more reliable order.
+*** Reports on where mail messages end up can be generated.
+`M-x nnmail-split-history'
+*** More hooks and functions have been added to remove junk
+from incoming mail before saving the mail.
+See `nnmail-prepare-incoming-header-hook'.
+*** The nnml mail backend now understands compressed article files.
+** Custom 1.86, courtesy of Per Abrahamsen
+The Customize library enables Emacs Lisp programmers to specify types
+of their variables, so that the users can customize them.
+Invoke the customizations buffer using the menus (Customize is at the
+top of the Options menu), or using commands `M-x customize',
+`M-x customize-variable' and `M-x customize-face'.  Customize can save
+the changed settings to your `.emacs' file.
+Customize is now the preferred way to change XEmacs settings.  Tens of
+packages have been converted to take advantage of the Customize
+features, including Gnus, Message, Supercite, Psgml, Comint, W3,
+cc-mode (and many other programming language modes), ispell.el,
+ps-print.el, id-select.el, most of the programming language modes, and
+many many more.
+See the "Lisp Changes" section later for a short description of why
+and how to add custom support to your Lisp packages.  Custom is also
+documented in the XEmacs info manuals.
+** W3-3.0.86, courtesy of William Perry
+Version 3 of Emacs/W3, the Emacs World Wide Web browser, has been
+included.  It is significantly faster than any of the previous
+versions, and contains numerous new features.
+** AUCTeX-9.7k, courtesy of Per Abrahamsen
+AUC TeX is a comprehensive customizable integrated environment for
+writing input files for LaTeX using Emacs.
+AUC TeX lets you run TeX/LaTeX and other LaTeX-related tools, such as
+a output filters or post processor from inside Emacs.  Especially
+`running LaTeX' is interesting, as AUC TeX lets you browse through the
+errors TeX reported, while it moves the cursor directly to the
+reported error, and displays some documentation for that particular
+error.  This will even work when the document is spread over several
+files.
+AUC TeX automatically indents your `LaTeX-source', not only as you
+write it -- you can also let it indent and format an entire document.
+It has a special outline feature, which can greatly help you `getting
+an overview' of a document.
+Apart from these special features, AUC TeX provides an large range of
+handy Emacs macros, which in several different ways can help you write
+your LaTeX documents fast and painless.
+** redo.el-1.01, courtesy of Kyle Jones
+redo.el is a package that implements true redo mechanism in XEmacs
+buffers.  Once you load it from your `.emacs', you can bind the `redo'
+command to a convenient key to use it.
+Emacs' normal undo system allows you to undo an arbitrary number of
+buffer changes.  These undos are recorded as ordinary buffer changes
+themselves.  So when you break the chain of undos by issuing some
+other command, you can then undo all the undos.  The chain of recorded
+buffer modifications therefore grows without bound, truncated only at
+garbage collection time.
+The redo/undo system is different in two ways:
+*** The undo/redo command chain is only broken by a buffer modification.
+You can move around the buffer or switch buffers and still come back
+and do more undos or redos.
+*** The `redo' command rescinds the most recent undo without
+recording the change as a _new_ buffer change.
+It completely reverses the effect of the undo, which includes making
+the chain of buffer modification records shorter by one, to counteract
+the effect of the undo command making the record list longer by one.
+** edmacro.el-3.10, courtesy of Dave Gillespie, ported to XEmacs by
+Hrvoje Niksic.
+Edmacro is a utility that provides easy editing of keyboard macros.
+Originally written by Dave Gillespie, it has been mostly rewritten by
+Hrvoje Niksic, in order to make it distinguish characters and integer,
+as well as to adapt it to XEmacs keysyms.
+Press `C-x C-k' to invoke the `edit-kbd-macro' command that lets you
+edit old as well as define new keyboard macros.  You can also edit the
+last 100 keystrokes and insert them into a macro to be bound to a key
+or named as a command.  The recorded/edited macros can be dumped to
+`.emacs' file.

+XEmacs now includes a minesweeper game with a full-featured graphics
+and mouse interface.  Invoke with `M-x xmine'.
+** efs-1.15-x5 courtesy of Andy Norman and Michael Sperber

+* Lisp and internal changes in XEmacs 20.2
+==========================================
+** `defcustom' and `defgroup' can now be used to specify types and
+placement of the user-settable variables.
+You can now specify the types of user-settable variables in your Lisp
+packages to be customized by users.  To do so, use `defcustom' as a
+replacement for `defvar'.
+For example, the old declaration:
+(defvar foo-blurgoze nil
+"*non-nil means that foo will act very blurgozely.")
+can be rewritten as:
+(defcustom foo-blurgoze nil
+"*non-nil means that foo will act very blurgozely."
+:type 'boolean
+:group 'foo)
+From a package writer's point of view, nothing has been changed
+However, the user can now type `M-x customize RET foo-blurgoze RET' to
+customize the variable.
+Other, more complex data structures can be described with `defcustom'
+too, for instance:
+(defcustom foo-hairy-alist '((somekey . "somestring")
+(otherkey . (foo-doit))
+(thirdkey . [1 2 3]))
+"*Alist describing the hairy options of the foo package.
+The CAR of each element is a symbol, whereas the CDR can be either a
+string, a form to evaluate, or a vector of integers.
+New Emacs users simply adore alists like this one."
+:type '(repeat (cons (symbol :tag "Key")
+(choice string
+(vector (repeat :inline t integer))
+sexp)))
+:group 'foo)
+The user will be able to add and remove the entries to the list in a
+visually appealing way, as well as save the settings to his/her
+`.emacs'.
+Note that `defcustom' will also be included in GNU Emacs 19.35, and
+that both XEmacs and GNU Emacs will be using it in the future.
+Although the user-interface of customize may change, the Lisp
+interface will remain the same.  This is why we recommend that you use
+`defcustom' for user-settable variables in your new Lisp packages.
+** The `read-kbd-macro' function is now available.
+The `read-kbd-macro' function (as well as the read-time evaluated
+`kbd' macro) from the edmacro package is now available in XEmacs.  For
+example:
+(define-key foo-mode-map (kbd "C-c <up>") 'foo-up)
+is completely equivalent to
+(define-key foo-mode-map [(control ?c) up] 'foo-up)
+The `kbd' macro is preferred over `read-kbd-macro' function , as it
+evaluates before compiling, thus having no loading overhead.
+Using `kbd' is not necessary for GNU Emacs compatibility (GNU Emacs
+supports the XEmacs-style keysyms), but adds to clarity.  For example,
+(kbd "C-?") is usually easier to read than [(control ??)].  The full
+description of the syntax of keybindings accepted by `read-kbd-macro'
+is documented in the docstring of `edmacro-mode'.
+** Overlay compatibility is implemented.
+The overlay support in XEmacs is now functional.  Written by Joe
+Nuspl, the overlay compatibility library overlay.el is implemented on
+top of the native XEmacs extents, and can be used as a GNU
+Emacs-compatible way of changing display properties.
+** You should use keysyms kp-* (kp-1, kp-2, ..., kp-enter etc.)
+rather than the old form kp_*.  The new form is also compatible with
+GNU Emacs.
+** The keysyms mouse-1, mouse-2, mouse-3 and down-mouse-1,
+down-mouse-2, and down-mouse-3 have been added for GNU Emacs
+compatibility.
+** A new user variable `signal-error-on-buffer-boundary' has been
+added.
+Set this to variable to nil to avoid XEmacs usual lossage of zmacs
+region when moving up against a buffer boundary.
+** lib-complete.el was MULE-ized.
+The commands `find-library', `find-library-other-window' and
+`find-library-other-frame' now take an optional coding system
+argument.
+** Experimental support for Lisp reader macros #-, #+.
+The Common Lisp reader macros for feature test are now supported.  This
+feature is present for evaluation purposes and is subject to change.
+** `values' now has a setf method
+** The `eval-after-load' and `eval-next-after-load' functions are
+now available.
+** A bug that prevented `current-display-table' to be correctly set
+with `set-specifier' has been fixed.
+** The bug in easymenu which prevented multiple menus from being
+accessible through button3 has been fixed.
+You can now safely use easymenu to define multiple menu entries in a
+compatible way, with the added menus accessible via button3 as local
+submenus.
+** Many bugs in the scrollbar code have been fixed.
+** First alpha level support of MS Windows NT is available, courtesy
+of David Hobley and Marc Paquette.
+** Wnn/egg now has initial support Courtesy of Jareth Hein.
+** Some old non-working code has been removed until someone chooses
+to work on it.
+This includes much of the NeXTStep stuff.  The VMS support is also
+likely to be removed in the future.
+** Many files have been purged out of the etc/ directory.
+If you still need the purged files, look for them in the GNU Emacs
+distribution.
+* Major Differences Between 19.14 and 20.0
+===========================================
+XEmacs 20.0 is the first public release to have support for MULE
+(Multi-Lingual Emacs).  The --with-mule configuration flag must be
+used to enable Mule support.
+Many bugs have been fixed.  An effort has been made to eradicate all
+XEmacs crashes, although we are not quite done yet.  The overall
+quality of XEmacs should be higher than any previous release.  XEmacs
+now compiles with nary a warning with some compilers.
+-- Multiple character sets can be displayed in a buffer.  The file
+mule-doc/demo in the distribution contains a greeting in many
+different languages.
+-- Although the Mule work is for all languages, particular effort has
+been invested in Japanese, with particular focus on Japanese users
+of Sun WorkShop.  Many menubar labels have been translated into
+Japanese.  Martin Buchholz, the maintainer of MULE features within
+XEmacs normally runs XEmacs in a Japanese language environment.
+Some of the other contributors are Japanese, most importantly
+Morioka Tomohiko, author of the TM package, providing MIME support
+for Mail and News.
+-- Input for complex Asian languages is supported via XIM, a mechanism
+introduced in X11R5 to allow applications to get localized input
+without knowledge of the language.  The way XIM works is that when
+the locale has a complex character set, such as Japanese, and extra
+minibuffer-like status window appears attached to various
+application windows, and indicates the status of the input method.
+Composed input in XEmacs should work the same as with other
+applications.  If Motif and Mule support is configured into XEmacs,
+then XIM support is automatically configured in as well.
+-- TM (Tools for Mime) now comes with XEmacs.  This provides MIME
+(Multipurpose Internet Mail Extensions) support for Mail and News.
+The primary author is Morioka Tomohiko.
+-- Japanese input can also be input using the `canna' input method.
+This support was contributed by Morioka Tomohiko.  Setting up canna
+usually requires more user effort (and better knowledge of Japanese!)
+than XIM, but provides a better-integrated input method.
+-- A mini-tutorial on using Mule:
+-- Every time data passes between XEmacs and the rest of the
+environment, via file or process input or output, XEmacs must
+convert between its internal multi-character representation and
+the external representation (`coding system').  Many
+difficulties with Mule are related to controlling these coding
+system conversions.
+-- file-coding-system, file-coding-system-for-read,
+overriding-file-coding-system, and file-coding-system-alist
+are used to determine the coding systems used on file input
+and output.
+-- For each process, (set-process-input-coding-system) and
+(set-process-output-coding-system) determine the coding
+system used for I/O from the process.
+-- Many other things are encoded using pathname-coding-system:
+-- file and directory names
+-- window manager properties: window title, icon name
+-- process names and process arguments
+-- XIM input.
+-- In many cases, you will want to have the same values for all
+the above variables in many cases.  For example, in a
+Japanese environment, you will want to use the 'euc-japan
+coding system consistently, except when running certain
+processes that do byte-oriented, rather than
+character-oriented I/O, such as gzip, or when processing Mail
+or News, where ISO2022-based coding systems are the norm,
+since they support multiple character sets.
+-- To add support for a new language or character set, start by
+trying to copy code in japanese-hooks.el.
+-- The traditional pre-Mule data conversion is equivalent to the
+'binary coding system under Mule.  In this case all characters
+are treated as iso8859-1 (i.e. characters for English + Western
+European languages).
+-- many fileio-related commands such as find-file and write-file
+take an extra argument, coding-system, which specifies the
+encoding to be used with the file on disk.  For example, here is
+a command that converts from the Japanese EUC to ISO2022 format:
+xemacs -batch -eval '(progn (find-file
+"locale-start.el.euc" (quote euc-japan)) (write-file
+"locale-start.el" nil (quote iso-2022-8-unix)))'
+Interactively, you can be prompted for a coding system by
+providing a prefix argument to the fileio command.  In
+particular, C-u C-x C-f is a useful sequence to edit a file
+using a particular coding system.
+-- In an Asian locale (i.e. if $LANG is set to ja, ko, or zh),
+XEmacs automatically sets up a language environment assuming
+that the operating system encodes information in the national
+version of EUC, which supports English and the national
+language, but typically no other character sets.
+-- Command line processing should work much better now - no more order
+dependencies.
+-- Many many package upgraded (thanks go to countless maintainers):
+-- ediff 2.64 (Michael Kifer)
+-- Gnus 5.2.40 (Lars Magne Ingebrigtsen)

+-- etags 11.78 (Francesco Potorti`)
+-- ksh-mode.el 2.9
+-- vhdl-mode.el 2.73 (Rod Whitby)
+-- id-select.el (Bob Weiner)
+-- EDT/TPU emulation modes should work now for the first time.
+-- viper 2.92 (Michael Kifer) is now the `official' vi emulator for XEmacs.

+-- crisp.el - crisp/brief emulation (Gary D. Foster)
+-- Johan Vroman's iso-acc.el has been ported to XEmacs by Alexandre Oliva
+-- psgml-1.01 (Lennart Staflin, James Clark)
+-- python-mode.el 2.83 (Barry Warsaw)
+-- vrml-mode.el (Ben Wing)
+-- enriched.el, face-menu.el (Boris Goldowsky, Michael Sperber)
+-- sh-script.el (Daniel Pfeiffer)
+-- decipher.el (Christopher J. Madsen)
+-- New function x-keysym-on-keyboard-p helps determine keyboard
+characteristics for key rebinding:
+x-keysym-on-keyboard-p: (KEYSYM &optional DEVICE)
+-- a built-in function.
+Return true if KEYSYM names a key on the keyboard of DEVICE.
+More precisely, return true if pressing a physical key
+on the keyboard of DEVICE without any modifier keys generates KEYSYM.
+Valid keysyms are listed in the files /usr/include/X11/keysymdef.h and in
+/usr/lib/X11/XKeysymDB, or whatever the equivalents are on your system.
+-- Installed info files are now compressed (support courtesy of Joseph J Nuspl)
+-- (load-average) works on Solaris, even if you're not root. Thanks to
+Hrvoje Niksic.
+-- OffiX drag-and-drop support added
+-- lots of syncing with 19.34 elisp files, most by Steven Baur
