Just running QA now, looks to have fixed a number of untraced SMB 2.0 issues with Windows 7 (besides the prev version tab) we found in 7.3.3 and 7.3.4.
I heard there is an FCP BURT in 7.3.5 that was found but isn't in 7.3.4 or prior releases... 7.3.5P1 will fix it and should be available soon (this week I think?)... if you have FCP LUNs, I would wait for P1.
