** In keymaps where SPC scrolls forward, S-SPC now scrolls backward.
This affects View mode, etc.
++++
+** The default value of `make-backup-file-name-function' is no longer nil.
+Instead it defaults to a function that does what the nil value used to.
+
** Help changes
+++
** Frame and window changes
++++
+*** The function `window-in-direction' introduced in Emacs 24.1 now
+takes additional arguments for specifying a reference point, wrapping
+selection around frame borders, and specifying ways to select the
+minibuffer window.
+
+++
*** New commands `toggle-frame-fullscreen' and `toggle-frame-maximized',
bound to <f11> and M-<f10>, respectively.
*** New hooks `focus-in-hook', `focus-out-hook'.
These are normal hooks run when an Emacs frame gains or loses input focus.
++++
*** Emacs can now change frame sizes in units of pixels, rather than
text rows or columns. When maximizing a frame or making it fullscreen,
remaining extra pixels are no longer given to the minibuffer, the rightmost
is non-nil, all frame size changes happen pixelwise and set the
corresponding size hints for the window manager.
++++
*** Emacs can now change window sizes in units of pixels.
Mouse-dragging a mode line or window divider now changes the size of
adjacent windows pixelwise. If the new option `window-resize-pixelwise'
window sizes now have an additional argument that allows changes to apply,
or values to be returned, in pixels instead of lines/columns.
++++
+*** The functions `window-body-height' and `window-body-width' now never
+count partially visible lines or columns if called with a nil PIXELWISE
+argument.
+
++++
*** Emacs can now draw dividers between adjacent windows. To put
dividers between side-by-side/vertically stacked windows customize the
frame parameters `right-divider-width' and `bottom-divider-width' to
two are useful to provide a 3D effect, or to better distinguish dividers
from surrounding display objects.
++++
*** New functions are provided to return the pixel sizes of window
components, namely `window-scroll-bar-width', `window-mode-line-height'
`window-header-line-height', `window-right-divider-width' and
`window-bottom-divider-width'.
++++
*** The new function `window-text-pixel-size' returns the size of the
text of a window's buffer in pixels. This allows functions like
`fit-frame-to-buffer' and `fit-window-to-buffer' to accurately fit a
window to its buffer as it will be displayed.
-*** `fit-window-to-buffer' can now resize windows horizontally.
++++
+*** `fit-window-to-buffer' can now resize windows in both dimensions.
This behavior is controlled by the new option
-`fit-window-to-buffer-horizontally'.
+`fit-window-to-buffer-horizontally'. The new option
+`fit-frame-to-buffer' allows to fit the window's frame to its buffer.

+*** `fit-frame-to-buffer' now fits frames in both dimensions. The new
+options `fit-frame-to-buffer-margins' and `fit-frame-to-buffer-sizes'
control the size of the frame and its position on screen.
+---
*** Temp Buffer Resize Mode can now adjust height and width of windows
and frames. `temp-buffer-resize-mode' is now able to adjust the height
and the width of a window displaying a temporary buffer. The new option
`display-buffer' choose or make a window at the bottom of the selected
frame.
++++
*** New display action function `display-buffer-no-window' to not
display the buffer in a window.
++++
*** New display action alist entry `allow-no-window' to indicate the
caller of `display-buffer' is ready to handle the case of not
displaying the buffer in a window.
** Indentation changes
++++
+*** `electric-indent-mode' is now enabled by default.
+Typing RET reindents the current line and indents the new line.
+`C-j' inserts a newline but does not indent. In some programming modes,
+additional characters are electric (eg `{').
+
++++
+*** New buffer-local `electric-indent-local-mode'.
+
+++
*** The behavior of `C-x TAB' (`indent-rigidly') has changed.
When invoked without a prefix argument, it now activates a transient
the text indentation in the region. Typing any other key resumes
normal editing behavior.
-*** `electric-indent-mode' is enabled by default.
-
+++
*** `tab-stop-list' is now implicitly extended to infinity by repeating
the last step. Its default value is changed to nil, which means a tab
+++
** Uniquify is enabled by default, with `post-forward-angle-brackets' style.
+In other words, if you visit two files that have the same base name,
+then rather than creating buffers basename and basename<2>,
+Emacs uses basename<dirA> and basename<dirB>. To change this,
+customize `uniquify-buffer-name-style'. Set it to nil for the old behavior.
+++
** New command `C-x SPC' (`rectangle-mark-mode') makes a rectangular region.
This searches the region for identical lines, and removes all but one
copy of each repeated line. The lines need not be sorted.
++++
+** `blink-matching-paren' now only highlights the matching open-paren
+by default, instead of moving cursor. Set this variable to `jump' to
+enable the old behavior.

* Changes in Specialized Modes and Packages in Emacs 24.4
*** EDE

**** The cpp-root project now supports executing a compile command.
It can be set through the new :compile-command slot or the
buffer-local variable `compile-command'.

Include directories now support out-of-tree build directories and
target architecture auto-detection.

** You can enable ElDoc inside the `eval-expression' minibuffer with:
** Package
++++
+*** The package library now supports digital signing of packages.
+Maintainers of package archives should consider signing their packages
+to enhance security.
+
++++
+**** If the user option `package-check-signature' is non-nil,
+Emacs tries to check package signatures at install time.
+The value `allow-unsigned' allows installation of unsigned packages.
+
++++
+**** The user option `package-unsigned-archives' lists archives where
+Emacs will not try to check signatures.
+
++++
+*** New option `package-pinned-packages'. This is useful if you have multiple
+archives enabled, with more than one offering a package that you want.
+
+++
*** In the `list-packages' buffer, you can use `f' (`package-menu-filter')
to filter the list of packages by a keyword.

+*** You can customize the SMIE indentation of a mode via `smie-config'.
+The command `smie-config-guess' can help you derive the appropriate
+indentation settings, if you provide it with an indented sample file.
+Use `smie-config-save' to save the result.
+
++++
+*** You can customize the SMIE indentation of a file by adding an entry to
+the file's local variables of the form: `eval: (smie-config-local '(RULES))'.

+*** New commands `smie-config-show-indent' and `smie-config-set-indent'.

* Incompatible Lisp Changes in Emacs 24.4
++++
+** Do not assume that the priority of all overlays will be numeric.
+(You should still only specify integer priorities on overlays you create.)
+If you need to sort arbitrary overlays into priority order, `overlays-at'
+can now optionally do this.
+
---
** `kill-region' has lost its `yank-handler' optional argument.
** The cars of the elements in `interpreter-mode-alist' are now
treated as regexps rather than literal strings.
+---
+** Overlay priority does not have to be nil or a non-negative integer.
+Overlay priority can be other kinds of Lisp objects. We didn't yet
+decide whether other types of values are stable enough, and therefore
+don't feel it's right to document them. For now, don't assume in your
+code that the values of overlay priority can only be either nil or an
+integer, always test them with an appropriate predicate to be one or
+the other.

+To use the old font backend, use the following on the command line:

GNUstep and Mac OS X 10.4 use the old font backend.
-To use the old backend by default, do on the command line:

-** Improved fullscreen support on Mac OS X.
-Emacs supports both native (Mac OS X 10.7 and newer) and "old style" fullscreen.
-Customize `ns-use-native-fullscreen' to change the style.
-For Mac OS X 10.7 and newer, native is the default.
