This release includes improvements to UTF8 handling and internationalization, fixes to file uploading, and several other issues.

Gotchas:

 * WebGUI 7.5.6 uses a Unicode database connection, but this can cause problems
   with old data stored in an erroneous format.  The 7.5.6 upgrade has been
   adjusted to compensate for this.  If you are upgrading from prior to 7.5.6,
   the data should be repaired automatically.  However, if you had already upgraded
   past 7.5.6, there is no automated way to resolve the differences in the data.
   For information on how to resolve this if you have already upgraded, see
        http://www.webgui.org/bugs/tracker/charset-db-connection
