After the upgrade to Mercurial 4.2, I've noticed that some supposed-to-be draft changesets on non-publishing repos like autoland are appearing as public. I'm not sure why this is. I haven't had time to investigate this yet, as I've been busy with the Mercurial security release fire drill. If I had to venture a guess, I'd say it has to do with replication.
Sheriffs: have any of you noticed this problem recently? (I'm optimistic this was cleared up by fixing the SSH disconnect issue by upgrading to a custom version of 4.2 in bug 1388135.)
I haven't seen anything like it, I think.
