+* Installation Changes in Emacs 24.5
+
++++
+** Building Emacs now requires C99 or later.
+
+** Building Emacs now requires GNU make.
+
+** By default, Emacs no longer works on IRIX. We expect that Emacs
+users are not affected by this, as SGI stopped supporting IRIX in
+December 2013. If you are affected, please send a bug report. You
+should be able to work around the problem either by porting the Emacs
+undumping code to GCC under IRIX, or by configuring --with-wide-int,
+or by sticking with Emacs 24.4.
+

+** The configure option `--with-pkg-config-prog' has been removed.

+for use in Emacs bug reports.

+\f
+* Editing Changes in Emacs 24.5
+
+Emacs now supports "bracketed paste mode" when running on a terminal
+that supports it. This facility allows Emacs to understand pasted
+chunks of text as strings to be inserted instead of interpreting each
+character in the pasted text as actual user input, resulting in a
+paste experience similar to that under a window system and significant
+performance improvements when pasting large amounts of text.

selection around frame borders, and specifying ways to select the
minibuffer window.
*** 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'

or values to be returned, in pixels instead of lines/columns.

*** 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.

+additional characters are electric (eg `{').
