As of June 9, 2012, our version of Blackboard is 9.1, Service Pack 7. This was primarily a maintenance service pack, so it won't look much different from what you've been seeing. Check out the changes in What's New in Blackboard 9.1, SP7.
Please note: Blackboard works best in tested OS/browser configurations. Find out if you're using a supported browser: Supported Browsers for Blackboard 9.1, SP7
As you prepare for your 12-13 courses, please check out Blackboard Essential Info.
Help tab: Don't forget that documentation is all linked from the "Help" tab after logging into Blackboard:

Unavailable courses that are older than two years will no longer be displayed to faculty. We believe that this will cut down on the number of courses listed and make management of course materials easier. Faculty can request access to older courses (up to 5 years) by sending an email to UnivITHelp@rochester.edu with the name of the course and the semester it was taught.
