Hibernate ORM 4.3.0.Beta5 发布，该版本对 JPA 2.1 的支持越来越完善了，包括：
- HHH-8478 - which should complete AttributeConverter support.
- HHH-8445 - which adds support for REF_CURSOR parameters and should complete StoredProcedureQuery support.
- HHH-8276 - which was the major prerequisite step for entity graph support. You'll be using that anytime you load entities directly or by to-one association.
- HHH-8523 - which improves support for parameters and returns using an explicit TemporalType and defined as Calendar
