1.2rc3 -- pushing back

According to the schedule (which I don't consider very rigid), we're set to tag rc3 today.

I see there are a number of PRs tagged for 1.2.x that it would be nice to polish a little before putting in, so I'm inclined to push back the rc3 tagging for a bit. I'm attending a conference Tues-Thurs, so probably wouldn't be able to look at this until Friday at the earliest, but I think that will give sufficient time to make these last few PRs as good as they can possibly be.

In the meantime, please label any PRs or Issues you're aware of that should go into 1.2.0 as 1.2.x -- I've done a few, but it's easy to miss things if I'm not entirely familiar with the content of a PR.
