+where a "Backspace" key is not provided (e.g. old DEC keyboards.)
 Unless our implementation has bugs, the only reason why you would want
 to set `delete-key-deletes-forward' to nil is if you want to use the
 Delete key to delete backwards, despite the presence (according to
 Xlib) of a BackSpace key on the keyboard.
 `case-fold-search'.
 The new behavior affects all functions performing interactive
 searches, like `zap-to-char', `list-matching-lines', `tags-search'
 etc.  The incremental search facility has always behaved that way.
+** Incremental search will now highlight all visible matches, making
+it easier to anticipate where consecutive C-s or C-r will place the
+point.  If you want to disable the feature, set
+`isearch-highlight-all-matches' to nil.
+** You can now use the buffer tabs to switch between buffers.  The
+tabs are located between the toolbar and the uppermost window, in a
+location called "gutter".  If you dislike the buffer tabs, you can
+disable them by specifying:
+(set-specifier default-gutter-visible-p nil)
+in your `.emacs'.  You can change the location of the gutter with
+`set-default-gutter-position', however currently only MS-Windows
+supports tab widgets with orientations other than vertical..
+** When you press RET at a minibuffer prompt that provides a default
+value, the value is stored in history instead of an empty line.  Also,
+you can now edit the default value by pressing the down arrow,
+accessing the logical "future" value.  Not all minibuffer prompts have
+yet been converted to support this feature.
 ** The rectangle functions have been almost completely rewritten in
 order to avoid inserting undesirable spaces, notably at the end of
 lines.  Two typical examples of the old behavior were
 `string-rectangle', which filled all lines up to the right side of the
 As a side effect, the FORCE argument to `move-to-column' now
 understands the special value `coerce', which means that the line
 should not be filled if it is too short to reach the desired column.

-** You can now customize and save comments for faces and variables.
-In Custom buffers, a new menu entry allows you to add and edit a
-comment.  Comments for variables can also be assigned by calling
-`customize-set-(value|variable)' with a prefix argument.
 ** XEmacs now locates the early package hierarchies at
 ~/.xemacs/mule-packages/ and ~/.xemacs/xemacs-packages/.  Previously,
 the early packages were located in ~/.xemacs/.
 ** New variable `mswindows-meta-activates-menu'.
 If you set this variable to nil then pressing the Alt key under
 MS-Windows will no longer activate the menubar. The default is t.
+** Pixel-based scrolling has been implemented.
+By default this will attempt to scroll in increments equal to the
+height of the default face. Set `window-pixel-scroll-increment' to
+modify this behaviour.
 ** Etags changes.
 *** In DOS, etags looks for file.cgz if it cannot find file.c.
 *** New option --ignore-case-regex is an alternative to --regex.  It is now
 possible to bind a regexp to a language, by prepending the regexp with
-{lang}, where lang is one of the languages that `etags --help' prints out.

 * Lisp and internal changes in XEmacs 21.2
 ==========================================
-** A new portable dumper is available.
+** A new portable dumper is available for beta testing.
 Olivier Galibert has written a portable dumper for XEmacs, based on
 initial work by Kyle Jones.  Normally, XEmacs C sources link into an
 executable called `temacs', which loads the Lisp code and "unexecs"
 into a proper `xemacs' executable.  The unexec() process is hard to
 dumping `xemacs.dmp'.  This is because Makefiles have not yet been
 modified to not expect `temacs' producing an `xemacs' executable.  You
 can try it out by simply running `src/temacs'.  If it starts without
 failure, the portable dumping worked.
+#### NOTE: the portable dumper is not really usable yet, because the
+state of built-in variables is not yet saved.  Olivier promised to fix
+it.  Nag, nag.
 ** Much effort has been invested to make XEmacs Lisp faster:
 *** Many basic lisp operations are now faster.
 This is especially the case when running a Mule-enabled XEmacs.
 The glyph system has been extended to allow the display of glyphs that
 are implemented as native window-system widgets.  Thus you can embed
 buttons, scrollbars, combo boxes, edit fields and progress gauges in a
 buffer.  As a side effect subwindow support now works once again.

+The buffers-tab functionality and progress gauge have been implemented

-Also, `init-file-user' has been obsoleted in the process.
+** `user-init-file' and `user-init-directory' are now absolute
+file/directory names.  Previously, both variables used to be relative
+to (concat "~" init-file-user).  This turned out to be too complicated
+for most packages (and some core Lisp files) to use correctly.  Also,
+the `init-file-user' variable has been obsoleted in the process.
+The user-visible options like `-u' have not changed their behaviour.
 ** XEmacs finally has an automated test suite!
 Although this is not yet very sophisticated, it is already responsible
 for several important bug fixes in XEmacs.  To try it out, simply use
 the makefile target `make check' after building XEmacs.
 friendlier, but actually faster than checking for C-g.
 ** Functions for decoding base64 encoding are now available; see
 `base64-encode-region', `base64-encode-string', `base64-decode-region'
 and `base64-decode-string'.
+** The functions `read-string', `read-expression', `eval-minibuffer',
+`read-variable', `read-command', `read-function', `read-number',
+`read-shell-command', `read-from-minibuffer', and `completing-read'
+now take an additional argument which specifies the default value.  If
+this argument is non-nil, it should be a string; that string is used
+in two ways:
+It is returned if the user enters empty input.
+It is available through the history command M-n.
+** LDAP changes.
+*** The LDAP interface now consists of two layers, a low-level layer
+that closely matches the LDAP C API, and a more convenient
+higher-level set of functions.
+*** The low-level functions that used to be named *-internal are now
+named more simply: `ldap-open', `ldap-close', `ldap-search-basic',
+`ldap-add', and `ldap-modify'.  They should be used directly for very
+specific purposes (such as multiple operations on a connection) only.
+*** The higher-level functions provide a more convenient way to access
+LDAP directories hiding the subtleties of handling the connection,
+translating arguments and ensuring compliance with LDAP
+internationalization rules and formats (currently partly implemented
+only.)  This layer provides atomic operations for searches,
+modification, addition and deletion of multiple entries at once:
+`ldap-search-entries', `ldap-add-entries', `ldap-delete-entries', and
+`ldap-modify-entries'.
+*** To maintain compatibility with previous code, the now obsolete
+function `ldap-search' is now merely a wrapper that calls either
+`ldap-search-basic' or `ldap-search-entries'.  Please don't use the
+`ldap-search' function in your new programs -- a direct call to one of
+the two replacements is more efficient and unambiguous.
 ** The arguments to `locate-file' are now more Lisp-like.  As before,
 the usage is:
 (locate-file FILENAME PATH-LIST &optional SUFFIXES MODE)
