I see that 1.6.0-GA has been formally released! YEAH!!!

We originally started building our application based on 1.5.0-GA and have been upgrading along as the patch releases came out. Is there an existing list of any schema changes that we should make sure are applied before we upgrade to 1.6.0-GA? If not, I guess I'll generate a new project based on the Maven archetype and get it to generate a new schema so I can do a diff.
Thanks for all your continual efforts!
