Whoops, wrong link :)

The release notes for 2.6.0 say that there is python3 support, but it
doesn't actually build. I see that the 3.0.0 alpha support done by a
handful of folks, but it's not clear from the issue tracker what the
status is. Anyway, good to hear that it will be supported, it
surprised me that it wasn't already.

Do you have any idea when a 3.0.0 final will be tagged? I don't mind
porting crit/p.haul to python3, but I would like to have something
that we can release in Ubuntu 16.04.
