Jose Barreto just informed me that he has an excellent list of what has changed between Server 2008 Beta 3 and Server 2008 June CTP. The link shows what changed with Enterprise Edition and Server Core. What I really enjoy about this list is that:

1. It is simple to read and understand (follows the KISS rule)
2. It shows what is new from Beta 3
3. Shows the newly renamed features

Thanks for the update Jose this is something I have been waiting to see!
