Hi all, in previous emails I mentioned I suggested to release a JPA3 compatible version of Hibernate ORM out soon, as I expected this to be the natural way forward, and soon to be needed by other projects such as WildFly. I had started working on this myself. However, the WildFly team hasn't decided if/when they will adopt the new Jakarta EE APIs, and I've been advised by many that this upgrade is unlikely to be in high demand: it brings no new benefits at all, while it introduces quite some annoying breaking changes. We have a fairly complete prototype in the draft PR I've sent here: - https://github.com/hibernate/hibernate-orm/pull/3373 And yet, I think I'll "put it in the freezer". Unfortunately I had already merged some preparations work in 5.5, such as upgrading to Validator 7.x: I will revert those changes, apologies for that mess but I think it's for the best to postpone this for later. When there will be more interest in this, it should not be too hard to adapt the work as it's mostly strucutured in the form of replacement scripts which should apply nicely w/o any conflict even on future branches. Thanks, Sanne
