 * Changes in Emacs 21.1
 
+** Changes to etags.el
+
+*** You can display additional output with M-x tags-apropos by setting
+the new variable tags-apropos-additional-actions.
+
+If non-nil, the variable's value should be a list of triples (TITLE
+FUNCTION TO-SEARCH).  For each triple, M-x tags-apropos processes
+TO-SEARCH and lists tags from it.  TO-SEARCH should be an alist,
+obarray, or symbol.  If it is a symbol, the symbol's value is used.
+
+TITLE is a string to use to label the list of tags from TO-SEARCH.
+
+FUNCTION is a function to call when an entry is selected in the Tags
+List buffer.  It is called with one argument, the selected symbol.
+
+A useful example value for this variable might be something like:
+
+  '(("Emacs Lisp" Info-goto-emacs-command-node obarray)
+    ("Common Lisp" common-lisp-hyperspec common-lisp-hyperspec-obarray)
+    ("SCWM" scwm-documentation scwm-obarray))
+
+*** The face tags-tag-face can be used to customize the appearance
+of tags in the output of M-x tags-apropos.
+
+*** Setting tags-apropos-verbose to a non-nil value displays the
+names of tags files in the *Tags List* buffer.
+
 ** Emacs can now support 'wheeled' mice (such as the MS IntelliMouse)
 under XFree86.  To enable this, simply put (mwheel-install) in your
 .emacs file.
