Actually, having just tried to do this, I'm not sure how it's meant to
work in practice.

Bumping unix's version requires relaxing the dependencies in Cabal and
haskeline on unix. One way to do this is to get upstream to relax the
dependency and updating our lagging repo. That will mean a version of
the library will be uploaded to hackage with the relaxed dependency. But
we don't know what the release 2.7.0.0 of unix will look like yet;
perhaps by the time it is released it will not work with the current
Cabal/haskeline code.

The other way is to make local ghc-only changes to relax the
dependencies, but that would increase the risk that we'd release with a
ghc branch of the library by mistake.

Wouldn't it be better to go back to the previous scheme, where we didn't
update version numbers until release time?


Thanks
