Hi Leif,
Was wondering if we should make a tool or if we already have one to see which packages we maintain have updates available.
I use the following short program to do that: http://github.com/peti/arch-haskell/blob/master/scripts/find-updates.hs
One thing that could be done would be monitoring the .rss feed version of this page: http://hackage.haskell.org/packages/archive/recent.html
Yes, that would be quite straight-forward, too.
Those of course would want to be checked against something like http://packdeps.haskellers.com/ and/or http://bifunctor.homelinux.net/~roel/hackage/packages/archive/pkg-list.html to make sure the updates won't break things.
We also have http://github.com/peti/arch-haskell/blob/master/scripts/find-conflicts.hs ..., which verifies that all dependencies in a given package set can be fulfilled. Take care, Peter
