+
+** C-u M-x goto-line now switches to the most recent previous buffer,
+and goes to the specified line in that buffer.
+
+When goto-line starts to execute, if there's a number in the buffer at
+point then it acts as the default argument for the minibuffer.
+
+** Emacs now responds to mouse-clicks on the mode-line, header-line and
+display margin, when run in an xterm.
+
+** M-SPC (just-one-space) when given a numeric argument N
+converts whitespace around point to N spaces.
+
+** Control characters and escape glyphs are now shown in the new
+escape-glyph face.
+
+** Non-breaking space and hyphens are now prefixed with an escape
+character, unless the new user variable `show-nonbreak-escape' is set
+to nil.
+
+---
+** The type-break package now allows `type-break-file-name' to be nil
+and if so, doesn't store any data across sessions. This is handy if
+you don't want the .type-break file in your home directory or are
+annoyed by the need for interaction when you kill Emacs.
+
+** display-battery has been replaced by display-battery-mode.
** calculator.el now has radix grouping mode, which is available when
`calculator-output-radix' is non-nil. In this mode a separator
boundries etc. For more info, see the documentation of the variable
`calculator-radix-grouping-mode'.

** You can now follow links by clicking Mouse-1 on the link.
Traditionally, Emacs uses a Mouse-1 click to set point and a Mouse-2
click to follow a link, whereas most other applications use a Mouse-1
click for both purposes, depending on whether you click outside or
-inside a link. With release 21.4, the behaviour of a Mouse-1 click

cursor, and the fancy startup screen.

+** New command line option -nbc or --no-blinking-cursor disables
+the blinking cursor on graphical terminals.
+
** C-h v and C-h f commands now include a hyperlink to the C source for
variables and functions defined in C (if the C source is available).
*** Grep commands now have their own submenu and customization group.
++++
+*** `grep-find' is now also available under the name `find-grep' where
+people knowing `find-grep-dired' would probably expect it.
+
*** The new variables `grep-window-height', `grep-auto-highlight', and
`grep-scroll-output' can be used to override the corresponding
compilation mode settings for grep commands.
*** Buffers are saved in the desktop file in the same order as that in the
buffer list.
+*** The desktop package can be customized to restore only some buffers immediately,
+remaining buffers are restored lazily (when Emacs is idle).
+
*** New commands:
- desktop-revert reverts to the last loaded desktop.
- desktop-change-dir kills current desktop and loads a new.
- desktop-save-in-desktop-dir saves desktop in the directory from which
it was loaded.
+ - desktop-lazy-complete runs the desktop load to completion.

*** New customizable variables:
- desktop-save. Determins whether the desktop should be saved when it is
killed.
- - desktop-file-name-format.
+ - desktop-file-name-format. Format in which desktop file names should be saved.

+*** isearch in Info uses Info-search and searches through multiple nodes.
+Failed isearch wraps to the top/final node. The user option
+`Info-isearch-search' controls whether to use Info-search or the
+default isearch search function.
*** New search commands: `Info-search-case-sensitively' (bound to S),
`Info-search-backward', and `Info-search-next' which repeats the last
search without prompting for a new search string.
+*** New command `Info-history-forward' (bound to r and new toolbar icon)
+moves forward in history to the node you returned from after using
+`Info-history-back' (renamed from `Info-last').
+
*** New command `Info-history' (bound to L) displays a menu of visited nodes.
*** New command `Info-toc' (bound to T) creates a node with table of contents
** Unexpected yanking of text due to accidental clicking on the mouse
wheel button (typically mouse-2) during wheel scrolling is now avoided.

optional arguments, in order to only report on the specified holiday

** New user option `add-log-always-start-new-record'.
---
** Rmail now displays 5-digit message ids in its summary buffer.
++++
+** Support for `movemail' from GNU mailutils was added to Rmail.
+This version of `movemail' allows to read mail from a wide range of
+mailbox formats, including remote POP3 and IMAP4 mailboxes with or
+without TLS encryption. If GNU mailutils is installed on the system
+and its version of `movemail' can be found in exec-path, it will be
+used instead of the native one.
+
---
** On MS Windows, the "system caret" now follows the cursor.
This enables Emacs to work better with programs that need to track
`list-colors-display' shows the list of System color names, in case
you wish to use them in other faces.
+---
+** On MS Windows NT/W2K/XP, Emacs uses Unicode for clipboard operations.
+Those systems use Unicode internally, so this allows Emacs to share
+multilingual text with other applications. On other versions of
+MS Windows, Emacs now uses the appropriate locale coding-system, so
+the clipboard should work correctly for your local language without
+any customizations.

+** `suppress-keymap' now works by remapping `self-insert-command' to
+the command `undefined'. (In earlier Emacs versions, it used
+`substitute-key-definition' to rebind self inserting characters to
+`undefined'.)

:propertize and :eval forms in the value of a variable whose
`risky-local-variable' property is nil.

+* Lisp Changes in Emacs 22.1

+** An element of buffer-undo-list can now have the form (FUNNAME .
+ARGS), where FUNNAME is a symbol other than t or nil. That stands for
+a high-level change that should be undone by evaluating (apply FUNNAME
+ARGS).
+
++++
+** The line-move, scroll-up, and scroll-down functions will now
+modify the window vscroll to scroll through display rows that are
+taller that the height of the window, for example in the presense of
+large images. To disable this feature, Lisp code may bind the new
+variable `auto-window-vscroll' to nil.
