[Nix-dev] Say hello to Haskell Platform 2012.4.0.0 (was: Should we switch the default Haskell compiler to GHC 7.4.2?)

[Peter Simons]

Hi guys,

we have switched our default Haskell environment to Haskell Platform
version 2012.4.0.0. This means that GHC 7.4.2 is now the default
compiler.

As far as I can tell, all packages built fine. Anyway, please let me if
you run into any trouble because of that change.

Take care,
Peter
