Hi,

I heard on the #haskell irc channel that there might be a way to get cabal to automatically update a new version of ghc with all the previously installed packages. Is that true? If so, I would love to know how.

Yes, I was referring to a feature in cabal-install for which there are patches available (by Peter Robinson) but I have not yet got round to reviewing and applying them. So the answer is wait for the next release. Duncan
