Ah, great !   on PyPI side, we will be able to mark releases as being
beta thanks to PEP 386.
Maybe the simple index could differentiate them somehow.

+1. An explicit upgrade step would be perfect: people won't have to

by adding options. I am wondering how hard it would be to apply the
same principal
to all eggs in the buildout, but maybe this is a bit out of scope
