* [[Dynamic_Live_Mode|Dynamic Live Mode (DLM)]] - All MetaClasses are always in Live Mode now. If you change a MetaClass, {{UBIK}} adapts the database automatically.
* Relational Polymorphism - Override MetaProperty assignments for MetaClasses and MetaProxyProperty assignments for MetaProxies.
Revision D:
* A set of methods for hard-deleting objects from the database is now available for the IDataFactory:
<syntaxhighlight lang="csharp">
bool HardDeleteRecords(MetaClass mc, DateTime? markedBefore = null);
bool HardDeleteRecords(MetaClass mc, List<Guid> idsToDelete);
</syntaxhighlight>
E.g.:
<syntaxhighlight lang="csharp">
environment.UBIKDataFactory().HardDeleteRecords(metaclass);
</syntaxhighlight>
