+* About external Lisp packages
+
+When you upgrade to Emacs 22 from a previous version, some older
+versions of external Lisp packages are known to behave badly.
+So in general, it is recommended that you upgrade to the latest
+versions of any external Lisp packages that you are using.
+
+You should also be aware that many Lisp packages have been included
+with Emacs 22 (see the extensive list below), and you should remove
+any older versions of these packages to ensure that the Emacs 22
+version is used.  You can use M-x list-load-path-shadows to find such
+older packages.
+
+Some specific packages which are known to cause problems are:
+
+** CEDET (upgrade to lastest version)
+** cua.el, cua-mode.el (remove old versions)
