I'm probably going to push the release back to this Friday if that's cool with everyone.

There's some regression fixes that I'd like to get into 2.1.4.

Note that this will be the last release of the 2.1.x series (assuming no surprises happening), so if you have something you'd like to get in, it'd be good to edit the OP to keep track of that.
