* Changes in Emacs 21.4
+** When used interactively, `format-write-file' now asks for confirmation
+before overwriting an existing file, unless a prefix argument is
+supplied. This behavior is analogous to `write-file'.
+
+** You can now use Auto Revert mode to `tail' a file.
+If point is at the end of a file buffer before reverting, Auto Revert
+mode keeps it at the end after reverting. Similarly if point is
+displayed at the end of a file buffer in any window, it will stay at
+the end of the buffer in that window. This allows to tail a file:
+just put point at the end of the buffer and it will stay there. This
+rule applies to file buffers. For non-file buffers, the behavior may
+be mode dependent.
+
** Auto Revert mode is now more careful to avoid excessive reverts and
other potential problems when deciding which non-file buffers to
revert. This matters especially if Global Auto Revert mode is enabled

+
+ * backups.texi: Various small changes in addition to:
+ (Making Backups): Mention return value of `backup-buffer'.
+ (Auto-Saving): Mention optional FORCE argument to
+ `delete-auto-save-file-if-necessary'.
+ (Reverting): Mention optional PRESERVE-MODES argument to
+ `revert-buffer'. Correct description of `revert-buffer-function'.
