Project Revisions in v11

Just starting to explore v11 (Enterprise). Reading one of the older blog posts, I saw a couple really great features.

• Revisions. You can review all revisions, can open an old version of the project in read-only mode, can rollback to that revision if required. Open two copies of the same project in two different instances of PHPRunner or ASPRunner.NET, one is current and another one is an older revision, and then copy something from one project to another.
• Adding comments to saves/revisions ( manually and automatically ). Comments will be searchable that will help you quickly locate the revision you looking for.

I have not been able to find these in v11. I cannot find anything in v11 that allows me to access pervious revisions of my project. Am I looking right past it somewhere?
