Title: Cherry-picked commits from 0.12.1 release

At release time, there are always a bunch of little things that I end up fixing, and it's not practical to hold up the actual release to review them (we'd never release, basically). But now that 0.12.1 is out, it's worth reviewing those changes *for 0.13*, since we're in no hurry. I applied only the commits I made today during the release work, so most of this should be very safe.
