No. I think it was 3.1.0.beta3.
Glancing at my badge notifications, they were awarded long ago.
I told people to click “Dismiss” and call me in the morning.
It was an import, but I don’t think anyone has moved things around.
My current best guess is that they didn’t notice these notifications before (but weren’t they the same just 2 beta releases ago?) and if they click Dismiss it’ll be OK.
Thanks for your help.
I moved this to Support . Had it been earlier in the day yesterday I’d have done more to try to figure this out, but they were all yelling and I was about to quit fo the day. It was minutes after the upgrade (why did I upgrade so late in the day? 
) so I thought I’d post in case it was something we should worry about.
