+	* Added new OPimEventSortVector class, improved OPimSortVector
+	* OPimAccessBackend now supports generic sorting.
 2005-01-03 Stefan Eilers <stefan@eilers-online.net>
 	* Fixing bug in API documentation
 	* Moving hasQuerySettings() and querySettings() to OPimAccessTemplate to be available for all frontends
 2004-12-28  Stefan Eilers <stefan@eilers-online.net>
 	* Make improved query by example accessable via frontend
 	* Some API documentation improvement
 	* Cleanup of backend api..
 	* Fixing bug #1501
 2004-11-23  Stefan Eilers <stefan@eilers-online.net>
 	* Implement fast and full featured version of sorted() for addressbook
 	* Implement generic queryByExample for all Addressboook backends. It allows incremental search.
 	* Update of API Documentation
