Thanks for the feedback!
Josh, we are preparing the official announcement and release notes, they should be on our web site shortly. We are not able to provide the changes in the ControlTemplates. There are almost no changes in them, so we suggest you to take only those for the Images and Documents module for now. If you experience any problems - please get back to us.
One more thing that was supposed to be a secret - we are working on different concept with the templates. Starting from the next major version, you will not have to worry about overriding your changes in templates after upgrading.
