You upgraded early too though so...
Not trying to win any points here. Point fingers wherever but at the end of the day, the decision to upgrade is your own and should always be based on your own testing. If on Cloud, let someone else suffer first. If self-hosted, test because you can.
I am sticking on 4.7.10 for the moment - I tested 4.7.11 beta 1, reported stuff i found, saw those were fixed in beta 2 and then final appeared. It's the weekend so I am not touching the final release.
