Any FTD 6.4.0.8 issues, mainly concerning Anyconnect VPN?

Hey! Just wanted to check of anyone here have run into any major issues with version 6.4.0.8?

We're about to upgrade our 2110's this weekend because of some major bugs in our current version (6.4.0.6) . And we've had some major bugs in 6.5.x so we're avoiding that track for now.

6.4.0.7 is the recommended for now but the there are quite a few bugs fixed in 6.4.0.8

Main concern in Anyconnect VPN, since we're going live with our deployment on Monday.

Thanks!
