Reviewed my server versions after rolling back to 7.6.3.20, that was a misunderstanding on my part. It's just 6.5 that we are primarily running that is now incompatible. I was mixing that up with another hypervisor's versioning system.

Wish there had been a notice that backwards compatibility was literally being nixxed. This removed compatibility with everything from XS 4.x to 6.5 which is 93% of the servers I had it hooked to.

If you don't mind, can you comment on that change in the release notes?
