*** New property `scroll-command' should be set on a command's symbol to
define it as a scroll command affected by `scroll-preserve-screen-position'.
*** `menu-bar-select-buffer-function' lets you choose another operation
instead of `switch-to-buffer' when selecting an item in the Buffers menu.
+** Window changes
+
++++
+*** Resizing an Emacs frame now preserves proportional window sizes,
+modulo restrictions like window minimum sizes and fixed-size windows.
+
+*** The behavior of `display-buffer' is now customizable in detail.
++++
+**** New option `display-buffer-base-action' specifies a list of
+user-determined display "actions" (functions and optional arguments
+for choosing the displaying window).
+
+This takes precedence over the default display action, which is
+specified by `display-buffer-fallback-action'.
+
++++
+**** New option `display-buffer-alist' maps buffer name regexps to
+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-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 commands `maximize-window' and `minimize-window'.
+These maximize and minize the size of a window within its frame.
+
++++
+*** New commands `switch-to-prev-buffer' and `switch-to-next-buffer'.
+These functions allow to navigate through the live buffers that have
+been shown in a specific window.
+
++++
+*** New functions `window-state-get' and `window-state-put'.
+These functions allow to save and restore the state of an arbitrary
+frame or window as an Elisp object.
+
** The inactive minibuffer has its own major mode `minibuffer-inactive-mode'.
This is handy for minibuffer-only frames, and is also used for the "mouse-1
pops up *Messages*" feature, which can now easily be changed.
*** M-s C-e in Isearch is now bound to isearch-yank-line.

+** The default value of redisplay-dont-change 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.

+original buffers. It is bound to "e" in Occur mode.
** New global minor modes electric-pair-mode, electric-indent-mode,
and electric-layout-mode.
** 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.
+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
+set to any of the values 'below, 'right, 'above, or 'left to make the
+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.
+
++++
+*** `adjust-window-trailing-edge' adjustments.
+`adjust-window-trailing-edge' can now deal with fixed-size windows and
+is able to resize other windows if a window adjacent to the trailing
+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
+from display in a window will preferably show the buffer previously
+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.
-*** FIXME: buffer-display-alist changes
+*** `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.
+
+*** Display actions
+
+**** The second arg to `display-buffer' and `pop-to-buffer' is now
+named ACTION, and takes a display action of the same form as
+`display-buffer-base-action' (see Changes, above). A non-nil,
+non-list value is treated specially, as the old meaning.
+
+**** New variable `display-buffer-overriding-action'.
+
+**** The procedure of `display-buffer' etc. to choose a window is
+determined by combining `display-buffer-overriding-action',
+`display-buffer-alist', the ACTION arg, `display-buffer-base-action',
+and `display-buffer-fallback-action'. The second and fourth of these
+are user-customizable variables.
+
+See the docstring of `display-buffer' for details.
+
++++
+*** New behavior of `quit-window'.
+The behavior of `quit-window' has been changed in order to restore the
+state before the last buffer display operation in that window.
