GHC 6.8 has just made it into Debian in a usable form. (w00t!)

Due to the library split my old cabal files don't work any longer. updating them isn't the problem, the problem is keeping them compatible with both versions of Cabal. I searched the wiki (quickly) but didn't find anything on this topic. Is there a cookbook out there for it?

Cabal is backwards compatible for .cabal files, so if it works with the old one it'll still be ok. If you need a complex custom Setup.hs file then that's quite a different matter and there's no sensible way of making that work with both (unless you can find some hack using type classes or cpp). If you want to take advantage of new features in Cabal then unless it's something very simple like using new fields (which old cabal versions will warn about but otherwise ignore) then you can't really use them and remain compatible with older cabal versions. This applies particularly to the new configurations which uses new syntax that the Cabal-1.1.x versions to not understand. Duncan
