We already have that in place, and once we release we'll be much
stricter with version number checks.  But we didn't actually bump the
version number with this change (perhaps we should have, I hope it
won't be too much of a hassle since right now only people running off
git can use it, and it's a 'git pull' away).

Currently the version string is at v2, and when we make another round
of larger changes post 0.12 for features we want in that case, we'll
certainly update that.
