Quick update. The repos have been updated and the mirrors should be all up-to-date within a few hours. That's the second time this has happened in recent months and it we certainly have to make sure it doesn't happen again.
I've just looked at the ClearCARE support queue and I'm not seeing any open issues that seem to have been related to the 6.6 roll-out.
Granted, it didn't go perfectly and we're looking at ways in v7 to be able to stagger the updates so we can have the same sort of QC process that is in place and successful in normal updates (eg. goes to Community firs for testingt unless security-related and deemed urgent, in which case it's reversed), however, any Pro users who had problems were handled by the ClearCenter support team (not on Community forums but through the support ticket queue).
If you have any issues related to 6.6 update and are on Professional, please, throw us a ticket, even if you don't have a subscription that includes support. At least it will be logged and reviewed by the devel team, and if we've broken something for the masses, we'll fix it...we're not going to ding you for per-incident costs. That would be...dirty.
