I know you have been waiting in anticipation, but now it is available - Hibernate Validator 5.2.1.Final :-). Given that it is a drop-in replacement for all 5.x releases, there is no reason to delay an upgrade. Just go and get it.
For the more cautious, here again the highlights of the 5.2 release with pointers to more information.
Moving along towards a 5.2 Final, we are happy to announce the release of Hibernate Validator 5.2.0.CR1. The main goal of this release was to fix bugs and polish some of the new features. For example, we reviewed the Optional validation support and made sure its behavior is (what we think) consistent in all cases. You can find the full change log on JIRA.
Following on the heels of 5.2.0.Final, Hibernate Search 5.3.0.Beta1 is now out. This time the faceting engine got an overhaul.
While working on the finishing touches for Hibernate Search 5 and updating the projects integrating with Hibernate Search, we discovered a couple of issues which we needed to address to proceed. So without further ado, here comes:
After some time in the making, we are happy to announce the first Hibernate Validator release of the 5.2 series - 5.2.0.Alpha1. This release focuses mainly on Java 8 support, but we will get to this in a bit.
I am happy to announce Hibernate Validator 5.1.0.CR1, hopefully (fingers crossed) the last release prior Final. We used the release for last adjustments and some bug fixes.
This is just a quick note that the Hibernate Metamodel Generator code has moved and is now, as of version 4.3.0.Final, part of Hibernate ORM. You can find it in the tooling/metamodel-generator sub-directory of ORM. Unfortunately this news have been falling under the table during the announcement of ORM 4.3.0.Final. After all the focus was on JPA 2.1 support :-)
