If you are interested in the changes from the Beta you can check this MSDN Page, you can find also a lot of information from the Visual Studio ALM Rangers, that released the Readiness RC Wave full of important information. We have a good improvement on the upgrade process as described in This post, that explains the new upgrade procedure and how the wizard can avoid breaking something if you have customized a standard TFS Process.
