 2004-12-28  Stefan Eilers <stefan@eilers-online.net>
 	* Make improved query by example accessable via frontend
-	* Some API improvement
+	* 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
 2004-11-18  Holger Freyther  <freyther@handhelds.org>
 	* Every Access can give a set of Occurrences for a period or a datetime
 	* QueryByExample, Find, Sort can be generically accessed by OPimBase 
 	  pointer interface
 	* OPimBackendOccurrence gets split up to OPimOccurrences by 
 	  OPimTemplateBase
 	* Add safeCast to various OPimRecords
 	* Kill memleak in OPimTodo
