It says that anything beyond the minor version is optional. Also, in the cabal files I looked at, most seemed to use the major version for dependencies, e.g. package >= 0.5 < 0.6.
So I wondered if I misunderstood, or if the maintainers of those packages just live with the risk of minor breakage once in a while.

But anyway, I'm not trying to be overly pedantic - I'm just new to the Haskell community, so I ask a lot of questions ;-)

Thanks again,
