And we now know that the version that will appear now is the version of the github release tag. Where exactly does that go?

Splendid

thank you both @davidhassell and @bnlawrence - BTW @davidhassell you can now access the development version (which is something like eg pyfive-1.1.0.dev2+gb796a04e4) - if you still see eg 0.10.guff, just do a pip install -e .
