 ** Code that uses `concat' with integer args now gets an error, as
 long promised.

-The new charsets `japanese-jisx0213-2', `mule-unicode-0100-24ff',
-`mule-unicode-2500-33ff', and `mule-unicode-e000-ffff' take up 4 slots
-for new charsets in the private area of the Mule internal character
-representation.  This might cause add-on packages which add
-dimension-2 charsets to fail, because there's no only 1 slot left for
-such charsets.  (There are still many free slots for dimension-1
-charsets.)
+** Not a Lisp incompatibility as such but, with the introduction of
+extra private charsets, there is now only one slot free for a new
+dimension-2 private charset.  User code which tries to add more than
+one extra will fail unless you rebuild Emacs with some standard
+charset(s) removed; that is probably inadvisable because it changes
+the emacs-mule encoding.  Also, files stored in the emacs-mule
+encoding using an Emacs 20 with additional private charsets defined
+will probably not be read correctly by Emacs 21.
