Hi,
Hibernate Validator 5.2.1.Final was just released. Most important
new feature is Java 8 support, but there is more - http://in.relation.to/2015/07/30/hibernate-validator-521-final/
All artifacts are available in the Maven repositories (JBoss and Maven Central), but distribution
bundle upload is still pending while SourceForge struggles to recover from its storage fault.
Enjoy!
