** Emacs can now be compiled with ACL support.
28 29
This happens by default if a suitable support library is found at
build time, like libacl on GNU/Linux.  To prevent this, use the
30
configure option `--disable-acl'.

** Emacs can now be compiled with file notification support.
33 34
This happens by default if a suitable system library is found at
build time.  To prevent this, use the configure option
35
`--without-file-notification'.  See below for file-notify features.
36
FIXME?  This feature is not available for the Nextstep port. (?)

decompress gzip- and zlib-format compressed data.

63 64 65 66 67 68 69 70 71 72
+++
** When initializing `load-path', an empty element in the EMACSLOADPATH
environment variable (either leading, e.g., ":/foo"; trailing, e.g.,
"/foo:"; or embedded, e.g., "/foo::/bar") is replaced with the default
load-path (the one that would have been used if EMACSLOADPATH was unset).
This makes it easier to _extend_ the load-path via EMACSLOADPATH
(previously, EMACSLOADPATH had to specify the complete load-path,
including the defaults).  (In older versions of Emacs, an empty element
was replaced by ".", so use an explicit "." now if that is what you want.)

73 74
+++
** The -L option, which normally prepends its argument to load-path,
75 76
will instead append, if the argument begins with `:' (or `;' on MS Windows;
i.e., `path-separator').
77

78 79 80 81 82 83
+++
** If you use either site-load.el or site-init.el to customize the dumped
Emacs executable, any changes to `load-path' that these files make
will no longer be present after dumping.  To affect a permanent change
to `load-path', use the `--enable-locallisppath' option of `configure'.

** New option `gnutls-verify-error', if non-nil, means that Emacs
should reject SSL/TLS certificates that GnuTLS determines as invalid.
(This option defaults to nil at present, but this is expected to change
in a future release.)

** Emacs now supports menus on text-mode terminals.
If the terminal supports a mouse, clicking on the menu bar, or on
sensitive portions of the mode line or header line, will drop down the
menu defined at that position.  Likewise, clicking C-mouse-2 or
C-mouse-2 or C-mouse-3 on the text area will pop up the menus defined
for those locations.

If the text terminal does not support a mouse, you can activate the
first menu-bar menu by typing F10, which invokes `menu-bar-open'.

If you want the previous behavior, whereby F10 invoked `tmm-menubar',
customize the option `tty-menu-open-use-tmm' to a non-nil value.
Glenn Morris's avatar
Glenn Morris committed

(Typing M-` always invokes `tmm-menubar', even if `tty-menu-open-use-tmm'
is nil.)

** The *Messages* buffer is created in `messages-buffer-mode',
a new major mode, with read-only status.  Any code that might create
the *Messages* buffer should call the function `messages-buffer' to do
so and set up the mode.

** Emacs now supports ACLs (access control lists).
120 121 122 123
+++
*** Emacs preserves the ACL entries of files when backing up.
+++
*** New functions `file-acl' and `set-file-acl' get and set the ACL
124 125 126
entries of a file.  On GNU/Linux, the POSIX ACL interface is used via
libacl.  On MS-Windows, the NT Security APIs are used to emulate the
POSIX ACL interfaces.
127

128 129 130 131 132 133
** Multi-monitor support has been added.

*** New functions `display-monitor-attributes-list' and
`frame-monitor-attributes' can be used to obtain information about
each physical monitor on multi-monitor setups.

134 135 136
*** The functions `display-pixel-width' and `display-pixel-height' now
behave consistently among the platforms: they return the pixel width
or height for all physical monitors associated with the given display

137
as if they were on X11.  To get information for each physical
138 139 140 141
monitor, use the new functions above.  Similar notes also apply to
`x-display-pixel-width', `x-display-pixel-height', `display-mm-width',
`display-mm-height', `x-display-mm-width', and `x-display-mm-height'.

*** The command `apropos-variable' is renamed to `apropos-user-option'.
`apropos-user-option' shows all user options while `apropos-variable'
shows all variables.  When called with a universal prefix argument,
the two commands swap their behaviors.  When `apropos-do-all' is
non-nil, they output the same results.

165 166 167 168

`describe-class', `describe-constructor' and `describe-generic' were
removed.

*** When using `create-image' with image data, you can pass a :format
attribute (via the property-list argument) in order to help
ImageMagick detect the image type.  The value should be a MIME
content-type that is found in the new variable `image-format-suffixes'.

190 191 192 193
*** New command `frameset-to-register' is now bound to `C-x r f', replacing
`frame-configuration-to-register'.  It offers similar functionality,
plus enhancements like the ability to restore deleted frames.  The
command `frame-configuration-to-register' still exists, but is unbound.

+++
Chong Yidong's avatar

196 197 198

*** Emacs can now draw dividers between adjacent windows.
To put dividers between side-by-side/vertically stacked windows
customize the frame parameter `right-divider-width'/`bottom-divider-width'
to some positive integer.  You can drag dividers with the mouse
(they show a corresponding cursor when the mouse hovers over them).
You can change the appearance of dividers by customizing the faces
`window-divider', `window-divider-first-pixel', and
`window-divider-last-pixel'.  The last two are useful to provide a 3D
effect, or to better distinguish dividers from surrounding display objects.

*** `split-window' is now a non-interactive function, not a command.
As a command, it was a special case of `C-x 2' (`split-window-below'),
and as such superfluous.  After being reimplemented in Lisp, its
interactive form was mistakenly retained.

using the scroll bar (i.e. dragging the thumb down even when the end
of the buffer is visible).

229 230 231
and `eval-print-last-sexp' (`C-j' in Lisp Interaction mode) can take a
zero prefix argument.  This disables truncation of lists in the output,
equivalent to setting `(eval-expression-)print-length' and

** `read-regexp-defaults-function' defines a function to provide default
values for reading regexps by commands like `rgrep', `lgrep' `occur',
`highlight-regexp', etc.  You can customize this to specify a function
that provides a default value from the regexp last history element,
or from the symbol found at point.

Chong Yidong committed

versions of a file exist, and the caller did not explicitly specify
which one to load, then the newer file is loaded.  The default, nil,
means to always load the .elc file.

* Editing Changes in Emacs 24.4

** Indentation changes

+++
*** The behavior of `C-x TAB' (`indent-rigidly') has changed.
When invoked without a prefix argument, it now activates a transient
mode in which typing <left>, <right>, <S-left>, and <S-right> adjusts
the text indentation in the region.  Typing any other key resumes
normal editing behavior.

** New option `visual-order-cursor-movement'.

bidirectional context.
