> Oh, that's very strange. The Mercurial and GitHub repos are supposed to be mirrors of each other. It looks like there might be an issue with the mirroring process. I'm not sure if it's automated or manual. Dan, any thoughts?

Yeah, I guess I haven't pushed the py3 branch from git to mercurial, and on to the main repo that redmine looks at. TBH it's a pain, and I'd be happy to just keep the py3 stuff on the github side to avoid having to sync that stuff.
