So a good solution to this would be to have two version bumps: one for
development (2.7.x.x) and another bump for the final release (126.96.36.199).
Then Cabal can make releases that relax the unix dependency to 2.7,
which is fine because we'll never make a release of 2.7, it just keeps
things working during development.

There were serious problems with that scheme too, which is why we
changed. We get into a situation where people can't test HEAD because
some packages don't work with it, and they can't be updated because we
haven't bumped the version numbers.
