I've also recently changed the version number scheme on most of the packages I maintain (which includes most of the packages required by Hope) from a date-based one to a major.minor scheme. This has the unfortunate side-effect of making newer versions have smaller version numbers than older ones, but it felt silly to start with a major version number of 2008. That might have been a bad decision.

The rPath Linux package management tool, conary, has a nice solution to the problem that software version numbers have inconsistent lexical ordering conventions between projects and sometimes within the same project. It does not compare version numbers at all, and (as far as I can tell) asks the package repository for the most recent package, unless you specify a particular version. Perhaps Cabal could do something similar?

Of course, this way you can't express "I want version >= 1.2" which is kind of a bummer.

Yeah, that would make specifying dependencies a bit of a drag. I think I'll just rerelease all the packages as version 3000.0.0 or something. Who cares if the version numbers look silly? /Björn
