+        * Make improved query by example accessable via frontend
+        * Some API improvement
 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
         * Add SortVector implementations for OPimTodo and OPimContact
         
         2004-??-??The Opie Team <opie@handhelds.org>
         * Implemented some important modifications to allow to use OPimRecords as it is, without
           have to cast them. This makes it possible to write applications which handling pim
           data in a generic manner (see opimconvertion tool) (eilers)
