Thanks, the latest is 12.5.6, released last week, I am avoiding it like the plague...and the bug fix doesn't apply to us.
I am going with 12.5.5 (released in August). I already have release keys (Cisco AM sent them over)... Hybrid services are on a separate VCS-C that is already 12.5. My plan is to get new certs if we have any issues Thanks!
