Hi, We just released Hibernate Validator 6.0.4.Final. The main point of this release is to provide a patch file for WildFly 11 Final but we also included some nice performance improvements and bugfixes. It is a recommended upgrade for everyone already using 6.0.x. For more information, read the announcement here: http://in.relation.to/2017/10/25/hibernate-validator-604-final-out/ Have a nice day! -- Guillaume
