++++
+*** The default of `send-mail-function' is now `sendmail-query-once',
which asks the user (once) whether to use the smtpmail package to send
email, or to use the old defaults that rely on external mail
facilities (`sendmail-send-it' on GNU/Linux and other Unix-like

of user names and passwords, that setting is now ignored; you will be
prompted for the user name and the password, which will then be saved

+see the auth-source manual. You may want to change the auth-source
+preferences if you want to store the credentials encrypted, for
+instance.)
You can also manually copy the credentials to your ~/.authinfo file.
For example, if you had

** Emacs server and client changes
+++
*** New emacsclient argument --frame-parameters can be used to set the
frame parameters of a newly-created graphical frame.

+*** If emacsclient shuts down as a result of Emacs signaling an
error, its exit status is 1.
+++
*** New emacsclient argument --parent-id ID.
** New basic faces `error', `warning', `success' are available to
highlight strings that indicate failure, caution or successful operation.
+---
** Lucid menus and dialogs can display antialiased fonts if Emacs is built
with Xft. To change font, use the X resource font, for example:
Emacs.pane.menubar.font: Courier-12
when `scroll-error-top-bottom' is non-nil.
+++
*** New variable `scroll-error-top-bottom' (see above).
-
++++
*** New scrolling commands `scroll-up-line' and `scroll-down-line'
scroll a line instead of full screen.
+++
by default.
** Menu-bar changes

+---
*** `menu-bar-select-buffer-function' lets you choose another operation
instead of `switch-to-buffer' when selecting an item in the Buffers menu.
display actions, taking precedence over `display-buffer-base-action'.
+++
-*** New option `window-nest'.
-The new option `window-nest' allows to return the space obtained for
-resizing or creating a window more reliably to the window from which
-such space was obtained.
+*** New option `window-combination-limit'.
+The new option `window-combination-limit' allows to return the space
+obtained for resizing or creating a window more reliably to the window
+from which such space was obtained.
+++
-*** New option `window-splits'.
-The new option `window-splits' allows to split a window that otherwise
-cannot be split because it's too small by stealing space from other
-windows in the same combination.
+*** New option `window-combination-resize'.
+The new option `window-combination-resize' allows to split a window that
+otherwise cannot be split because it's too small by stealing space from
+other windows in the same combination. Subsequent resizing or deletion
+of the window will resize all windows in the same combination as well.
+++
*** New commands `maximize-window' and `minimize-window'.
-These maximize and minize the size of a window within its frame.
+These maximize and minimize the size of a window within its frame.

*** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'.
prompts for a number to count from and for a format string.
+++
-** The default value of redisplay-dont-change is now t
+** The default value of redisplay-dont-pause is now t
This makes Emacs feel more responsive to editing commands that arrive
at high rate, e.g. if you lean on some key, because stopping redisplay
in the middle (when this variable is nil) forces more expensive
updates later on, and Emacs appears to be unable to keep up.
++++
+** The behavior of <TAB> for active regions in Text mode has changed.
+In Text and related modes, typing <TAB> (`indent-for-tab-command')
+when the region is active causes Emacs to indent all the lines in the
+region, aligning them with the line previous to the first line in the
+region (or with the left margin if there is no previous line).

+** MH-E has been upgraded to MH-E version 8.3.1.
See MH-E-NEWS for details.
** Modula-2 mode provides auto-indentation.
*** The command `rmail-epa-decrypt' decrypts OpenPGP data
in the Rmail incoming message.
-** Shell mode
+---
+*** The variable `rmail-message-filter' no longer has any effect.
+This change was made in Emacs 23.1 but was not advertised at the time.

+** Shell mode
++++
*** Shell mode uses pcomplete rules, with the standard completion UI.
-

*** The `shell' command prompts for the shell path name if the default
directory is a remote file name and neither the environment variable
$ESHELL nor the variable `explicit-shell-file-name' is set.

-If set to an appropriate regexp, Shell mode can track your cwd by
-reading it from your prompt.
-
---
** SQL Mode enhancements.
** VC and related modes
++++
*** Support for pulling on distributed version control systems.
-The vc-pull command runs a "pull" operation, if it is supported.

-means to prompt the user for specifics, e.g. a pull location.
+`C-x v +' (`vc-pull') runs a "pull" operation, if it is supported, to

**** `vc-update' is now an alias for `vc-pull'.
**** Currently supported by Bzr, Git, and Mercurial.
++++

shows a diff while querying the user. It defaults to t.
++++
*** Log entries in some Log View buffers can be toggled to display a
longer description by typing RET (log-view-toggle-entry-display).
In the Log View buffers made by `C-x v L' (vc-print-root-log), you can
**** Packages using Log View mode can enable this functionality by
binding `log-view-expanded-log-entry-function' to a suitable function.
++++
*** New command `vc-ediff' allows visual comparison of two revisions
of a file similar to `vc-diff', but using ediff backend.
---
*** `copyright-fix-years' can optionally convert consecutive years to ranges.
++++
*** New command `nato-region' converts text to NATO phonetic alphabet.
\f
** cl.el no longer provides `cl-19'.

+
** The following obsolete functions and aliases were removed:
comint-kill-output, decompose-composite-char, outline-visible,
internal-find-face, internal-get-face, frame-update-faces,
of the line.
** Window changes
-
+++
*** Window tree functions are accessible in Elisp.
Functions are provided to return the parent, siblings or child windows
of any window including internal windows (windows not associated with a
buffer) in the window tree.
-
+++
-*** Window manipulation can deal with internal windows.
+**** New function `window-valid-p' gives non-nil for live and internal
+windows.
++++
+**** Window manipulation can deal with internal windows.
Many window handling functions like `split-window', `delete-window', or
`delete-other-windows' as well as the window resizing functions can now
act on any window including internal ones.
-
+++
*** window-total-height/-width vs window-body-height/-width.
The function `window-height' has been renamed to `window-total-height'
and `window-width' has been renamed to `window-body-width'. The old
names are provided as aliases. Two new functions `window-total-width'
and `window-body-height' are provided.
-
+++
*** Window parameters specific to window handling functions.
For each window you can specify a parameter to override the default
behavior of a number of functions like `split-window', `delete-window'
and `delete-other-windows'. The variable `ignore-window-parameters'
allows to ignore processing such parameters.
-
+++
*** New semantics of third argument of `split-window'.
The third argument of `split-window' has been renamed to SIDE and can be
new window appear on the corresponding side of the window that shall be
split. Any other value of SIDE will cause `split-window' to split the
window into two side-by-side windows as before.
-
+++
*** Window resizing functions.
A new standard function for resizing windows called `window-resize' has
been introduced. This and all other functions for resizing windows no
longer delete any windows when they become too small.
-
+++
*** Deleting the selected window now selects the most recently selected
live window on that frame instead.
-
+++
*** `adjust-window-trailing-edge' adjustments.
`adjust-window-trailing-edge' can now deal with fixed-size windows and
edge cannot be shrunk any more. This makes its behavior more similar to
that of Emacs 21 without compromising, however, its inability to delete
windows which was introduced in Emacs 22.
-
+++
*** Window-local buffer lists.
Windows now have local buffer lists. This means that removing a buffer
shown in that window with its previous window-start and window-point
positions. This also means that the same buffer may be automatically
shown twice even if it already appears in another window.
-
+++
*** `switch-to-buffer' has a new optional argument FORCE-SAME-WINDOW,
which if non-nil requires the buffer to be displayed in the currently
selected window, signaling an error otherwise. If nil, another window
can be used, e.g. if the selected one is strongly dedicated.
-
++++
*** `split-window-vertically' and `split-window-horizontally' renamed
-to `split-window-above-each-other' and `split-window-side-by-side'
-respectively. The old names are kept as aliases.
-
+to `split-window-below' and `split-window-right' respectively.
+The old names are kept as aliases.
++++
*** Display actions
**** The second arg to `display-buffer' and `pop-to-buffer' is now
+++
*** The new option `frame-auto-hide-function' lets you choose between
-iconfying or deleting a frame when burying a buffer shown in a dedicated
+iconifying or deleting a frame when burying a buffer shown in a dedicated
frame or quitting a window showing a buffer in a frame of its own.
** Completion
** pre/post-command-hook are not reset to nil upon error.
Instead, the offending function is removed.
-** New low-level function run-hook-wrapped.
+** New hook types
+
+*** New function `run-hook-wrapped' for running an abnormal hook by
+passing the hook functions as arguments to a "wrapping" function.
++++
+*** New macro `with-wrapper-hook' for running an abnormal hook as a
+set of "wrapping" filters, similar to around advice.
** `server-eval-at' is provided to allow evaluating forms on different
Emacs server instances.
** frame-local variables cannot be let-bound any more.
+** Major and minor mode changes
+++
-** prog-mode is a new major-mode meant to be the parent of programming mode.
-The prog-mode-hook it defines can be used to enable features for
-programming modes. For example:
-(add-hook 'prog-mode-hook 'flyspell-prog-mode)
-enables on the fly spell checking for comments and strings for
-programming modes.
+*** `prog-mode' is a new major mode from which programming modes
+should be derived.
+
+**** `prog-mode-hook' can be used to enable features for programming
+modes, e.g. (add-hook 'prog-mode-hook 'flyspell-prog-mode) to enable
+on-the-fly spell checking for comments and strings.
+
+*** New hook `change-major-mode-after-body-hook', run by
+`run-mode-hooks' just before any other mode hooks.
-** define-minor-mode accepts a new keyword :variable.
+*** Enabled globalized minor modes can be disabled in specific modes,
+by running (FOO-mode-hook 0) via a mode hook.
+
+*** `define-minor-mode' accepts a new keyword :variable.
+++
** `delete-file' and `delete-directory' now accept optional arg TRASH.
** `facemenu-read-color' is now an alias for `read-color'.
The command `read-color' now requires a match for a color name or RGB
-triplet, instead of signalling an error if the user provides a invalid
+triplet, instead of signaling an error if the user provides a invalid
input.
** Tool-bars can display separators.
STARTTLS opportunistically or use plain SSL, depending on your needs.
Only versions 2.8.x and higher or GnuTLS have been tested.
+[FIXME: this statement needs clarifying, given that GnuTLS >= 2.6.6
+is the test used by configure.]
*** gnutls-log-level
Set `gnutls-log-level' higher than 0 to get debug output. 1 is for
** keymaps can inherit from multiple parents.
+** `debug-on-event' lets you debug Emacs when stuck because of inhibit-quit.
+
+++
** New reader macro ## which stands for the empty symbol.
This means that the empty symbol can now be read back. Also, #: by itself
** New make target `dist' to create binary distribution for MS Windows.
+** Function `w32-default-color-map' is now obsolete.
+
** On Nextstep/OSX, the menu bar can be hidden by customizing
