I have released version 2.2.0.
The most interesting addition is support for batch lazy loading and "query joins". This is useful from a performance perspective in a number of scenarios ... multiple OneToMany's, using maxRows and joining to a OneToMany etc.
Quite a few bugs fixed as well.
The list of Enhancements and Bugs fixed can be seen at:
