The second release candidate for Hibernate ORM 4.3.0 is just released. There were a few issues with CR1 that required a second CR, especially HHH-8739 and HHH-8759.
The full change log for the release can be seen at https://hibernate.atlassian.net/browse/HHH/fixforversion/15150.
In 2 weeks we'll decide whether a CR3 is needed or release Final at that time.
Thanks for all the feedback!
