Just to be clear, Cabal will always support every major GHC version going back several years. I think it even supports GHC 6.12 still and Duncan tests with it. But, sometimes a GHC change may require you to use a newer version of Cabal, for things to work. So this just means that Cabal isn't necessarily *future compatible* with future GHCs - they may change the package format, etc. But it is backwards compatible with existing ones. -- Regards, Austin Seipp, Haskell Consultant Well-Typed LLP, http://www.well-typed.com/ _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://www.haskell.org/mailman/listinfo/ghc-devs
