 --------------------------------------------------------------------
+     * The URL used by Display Message on Login always returns the user to 
+       the page where they logged in.  If your site depended on the old,
+       buggy behavior of returning the user to the home page after showing
+       a message, then in the Settings you can assign Redirect After Login Url
+       to /.
+
      * The UKPLayer - a slideshow that displays images as a movie - 
        is in WebGUI again. Licencing information was overlooked. An 
        upgrade to 7.10.1 will break the Matrix. This is fixed now.

      * WebGUI now depends on PerlIO::eol, for doing line ending translation.
