[Haskell-cafe] No upgrade of GHC version in Ubuntu repository

Hi Caffe, deb packages of GHC (and Haskell Platform) in Ubuntu's (LTS Precise, 12.04) "universe" are not upgrading at all. GHC package is almost two years old, still on version 7.4.1, and GHC site still recommends to use Haskell Platform from repository. Even kernel is upgrading more often, and one would expect it is much more difficult. :-) What would be the reason for that? Is it abandoned? Best regards, vlatko
