Haskell Platform 2014.2.0.0, based on GHC 7.8.3 just went alpha! I expect the platform team to run it through its paces and hope that we'll have no barrier to a release within two weeks at most - perhaps much sooner! If you want to be intrepid and try it - head to to the haskell-platform mailing list and look for announcements.

As for versioning: The situation is that we can't (on Mac OS X at least) install two versions of Platform at the same time with the same GHC release. For patch release, 2014.2.0.0 and 2014.2.x.y this is fine and probably what we want: If we update a patch release, we sort of want people to use that, and not use the earlier vesion anymore. 2014.4.0.0 will need a new version of GHC... or will else we'll live with the idea that it isn't installable at the same time as 2014.2.0.0.
