 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.
-** Info "dir" functionality merged from Emacs-19.34
+** Multiple Info `dir' functionality has been merged with GNU Emacs
+19.34.
-------------------  DRAFT ------------------
+XEmacs will now correctly merge all the `dir' files in
-At the time it is dumped, XEmacs will initialize the value of
+`Info-directory-list' (initialized from either `INFOPATH'
-`Info-default-directory-list' from the value of the environment
+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.
-#### BETA Note: if the package startup stuff moves or changes, this
-next paragraph may need fixing.
-At runtime, the XEmacs startup code will loop through that list and
-collect all of the directories in it that satisfy `file-directory-p',
-and then appends any site package info directories found... ?? How do
-you want this worded? XXXXX !!!! (bright red bold DRAFT)
-When you start the info reader, `Info-directory-list' is initialized
-from either the environment variable "INFOPATH", if it exists, or
-`Info-default-directory-list'.  The first directory in this list must
-contain a "dir" file like the one supplied with XEmacs.  Note that if
-an INFOPATH variable is used, that only the directories in that path
-will be searched; no package info paths will be appended, as `Info-
-default-directory-list' will be ignored in that case.
-All of the directories on `Info-directory-list' will be searched for
-"dir" files, which may be full fledged Info files containing subnodes
-as well as menus.  They are merged to become one Info directory, with
-menus in like-named subnodes being coalesced from the several "dir"
-files.
-BETA Note: I have not tested this very thouroughly.  Does anyone out
-there actually have a dir file with real `info' subnodes in it?  I
-will create one and try it as I learn how. - karlheg
-"localdir" files are looked for also, secondary to "dir"'s. A localdir
-file should look like a section of the Info directory menu:
-|
-|* Gnus::                The all seeing all knowing News and Mail
-|                         interface for XEmacs.
-|* Calc::                HP-48 alike Calculator that can do algebra
-|
-The info reader will insert its contents into the main Info directory
-either at the end of the (dir)Top node, beginning at and replacing a
-line that looks like:
-|
-|* Locals:
-|
-BETA-Note:  Coming soon...
-... or, below a line that contains the exact text:
-|
-|Locally installed XEmacs Packages
-|
-... by default.  (This text is configurable--- see:
-`M-x customize-variable Info-localdir-heading-regexp'
-The `Info-localdir-heading-regexp' may be underlined with *'s, ='s, or
--'s, like any Info topic header.  When `Info-fontify' is non-nil, the
-underlineing characters will be elided and the topic heading itself
-will be given a face, according to `Info-title-face-alist'.
 ** 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
 ** 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).
 ** 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'.
 ** 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 be examined through the Customize
+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'.
 not      M-x load-library <ret> pending-delete <ret>
 In .emacs:       Use       (turn-on-pending-delete)
 not       (load "pending-del")
-** Package starting changes.
-*** 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.
 ** XEmacs can now save the minibuffer histories from various
 minibuffers.  To use this feature, add the line:
 (savehist-load)
 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
 *** 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-group RET gnuserv RET'.
+`M-x customize RET gnuserv RET'.
-*** The `gnuattach' and `gnudoit' programs have been abandoned in
+*** The functionality of `gnuattach' and `gnudoit' programs is
-favor of `gnuclient', which now accepts the standard `-nw',
+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
 *** 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
 ==========================================
 ** `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.
 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...)
 `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))))
