New in JPA 2.1 Early Draft
By alexismp on Jan 24, 2012
The blog entry covers Stored Procedures (similar to named queries, defined on the entities themselves), bulk operations, new FUNCTION, ON, TREAT JPQL keywords, more alignment with CDI and unsynchronized persistence context.
There are more features planned for JPA 2.1 that didn't get in the early draft (such as multi-tenancy). As a reminder, EclipseLink is the reference implementation (RI) for this specification while GlassFish 4.0 will deliver the overal Java EE 7 RI.
