+ * 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) \ No newline at end of file
