Hi, It's with great pleasure that I announce the release of Hibernate Validator 6.0.0.Alpha1. This release is coordinated with the Bean Validation 2.0 Early Draft 1 release that happened earlier this week [1]. Hibernate Validator 6 will be the reference implementation of Bean Validation 2.0, but it's also a place to experiment with the future additions to the spec. Apart from initial Bean Validation 2.0 support, this version comes with a lot of good things: - some Java 8 goodness, - nested type use constraints and nested cascaded validation - lambda based constraint definition - Duration support (and a much improved java.time support coming as part of Bean Validation 2.0) As explained in the announce on in.relation.to [2], we are looking forward to your feedback on these features. They might be refined and included in the next Bean Validation 2.0 iteration if they get enough traction. Have a nice day!
