Bean Validation, Hibernate Validator (its Reference Implementation) and the Test Compatibility Kit have been handed over to the JCP for what is called the Final Approval Ballot. That's when the expert committee votes for the go / no-go of the specification going final as it is.
We have found a few glitches when working on both the RI and the TCK in the last month but everything is in order now. The biggest visible change for you is that we renamed @ValidateExecutable into @ValidateOnExecution and we added a way to disable method validation entirely via the XML deployment descriptor.
We worked hard to make a stellar TCK. Let's speak numbers: the specification has 549 assertions including 492 testable. We cover 98,8% of them with 1500 tests. Good luck to all future Bean Validation 1.1 implementors :)
Everything is already available for you to use:
