Does ACF 2021 Update 17 seem solid at this point? I thought there were some issues initially, but I'm not sure if they were all resolved or not?

Only issue I had was that the installer initially failed to run, for some unknown reason, on 2 of 4 servers. It may not have had anything to do with the actual installer, since copying a binary- and permission-identical one from a successful server fixed the issue in both cases. Other than that, beautifully uneventful.

Brian, its solid. I don't think there's any major blocker issues I know of.
