 ** Emacs can now draw horizontal scroll bars on some platforms that
 provide toolkit scroll bars, namely Gtk, Lucid, Motif and Windows.
-Horizontal scroll bars are turned off by default.  Use the command
-`horizontal-scroll-bar-mode' to toggle them on all frames; the frame
-parameter `horizontal-scroll-bars' to turn them on/off on individual
-frames; the function `set-window-scroll-bars' to turn them on/off on
-individual windows.

+Horizontal scroll bars are turned off by default.
+*** New mode `horizontal-scroll-bar-mode' to toggle horizontal scroll
+    bars on all existing and future frames.
+*** New frame parameters `horizontal-scroll-bars' and
+    `scroll-bar-height' to set horizontal scroll bars and their height
+    for individual frames and in `default-frame-alist'.
+*** New function `frame-scroll-bar-height' to return the height of
+    horizontal scroll bars on a specific frame.
+*** `set-window-scroll-bars' now accepts five parameters where the last
+    two specify height and type of the window's horizontal scroll bar.
+
+** The height of a frame's menu and tool bar are no more counted in the
+frame's text height.  This means that the text height stands only for
+the height of the frame's root window plus that of the echo area (if
+present).  This was already the behavior for frames with external tool
+and menu bars (like in the Gtk builds) but has now been extended to all
+builds.
+
+** Frames now do not necessarily preserve the number of columns or lines
+they display when setting default font, menu bar, fringe width, or
+scroll bars.  In particular, maximized and fullscreen frames are
+conceptually never resized if such settings change.  For fullheight and
+fullwidth frames, the behavior may depend on the toolkit used.
+*** New option `frame-inhibit-implied-resize' if non-nil, means that
+   setting default font, menu bar, fringe width, or scroll bars of a
+   specific frame does not resize that frame in order to preserve the
+   number of columns or lines it displays.
