hey Philipp, we have only tested this version (6.1.1) in our lab environment with no major issues found. everything seems to be working correctly. the only problem i have noticed so far was regarding SMB signed traffic where the traffic is marked with "W" flag (wan secure) instead of "X" (SMB signed traffic) but the traffic is getting optimized/accelerated anyway so i assume it's only a "cosmetic" issue.
However i do not have any experience with 6.1.1 version in a production network yet.
