i think that generally requirement to update libraries to meet 6.8 reqirements isn't a good idea. can we provide full support of old packages in 6.8, for example by inclusion both new and old Cabal versions in default installation?
FWIW, Cabal is independent of GHC, they are just distributed together. As such, updating packages adds a dependency on Cabal 1.2, not on GHC. Cabal intentionally uses only Haskell98 features in order to be as portable as possible. Having build environments require the latest version of the build tool is rather common, too. This is not necessarily good in any case[*], but we try to make it as little hassle as possible. / Thomas [*] .. I'd personally like to avoid these problems as well, but many seem to consider them as transitional, and I agree that, ATM, hackage is small enough to fix problems in a decent amount of time.
