* Changes in Emacs 21.4
+** Convenient commands to switch buffers in a cyclic order are C-x <left>
+(prev-buffer) and C-x <right> (next-buffer).
+
+** Commands winner-redo and winner-undo, from winner.el, are now bound to
+C-c <left> and C-c <right>, respectively. This is an incompatible change.
+
+** Help commands `describe-funcion' and `describe-key' now show function
+arguments in italics. To change the default highlighting customize the
+face `help-argument-name'.
