I just created a new “Projects Using Envers” wikipage; so if you are using Envers in your project, make sure to add it to the list! :) If you are not yet using Envers, don’t forget to check it out when you have to implement data auditing/versioning next time.
Also, my company, SoftwareMill, is providing Envers support and services. If you are interested in a feature being added or a bug fixed, don’t hesitate to contact us!
