Saul Giordani, from the community perspective, we are no longer maintaining Hibernate 4.x. Even within the 5.x release stream, we typically do not backport features to previous non-master branches unless there is team consensus or a strong community request that it makes sense to do so.

I'm going to go ahead and tentatively add 6.0.0.alpha1 to this issue, at least that gives you and others an idea when to likely expect it. If we decide to do another point-release of version 5.x and the code is ready, I may backport it to that.

Regarding 4.2.x support, if the author of the extension code base at https://github.com/skuzniarz/hibernate-envers-ext wishes to make a version that is available for 4.2.x users, they're welcomed to do so; however, I won't be officially on the community fork.
