GHC 7.8.3 release

[Manuel M T Chakravarty]

I believe #9078 affects all EDSLs that use Andy Gill’s stable name method to implement observable sharing. It certainly crashes Accelerate.

I would very much appreciate if 7.8.3 would be released in time to make it into the upcoming Haskell Platform. (If the platform would ship with 7.8.2., that would be a quite bad for all affected EDSL libraries.)

Do we know the projected release date for the platform?

PS: For Accelerate, the situation is actually rather awkward right now. Due to the changes re ambiguous signatures in GHC 7.8, Accelerate needs to introduce a breaking API change to compile with 7.8. However, we can’t really fully transition to 7.8 until #9078 is fixed.
