Gearing up (again) for the next release: 2014.2.0.0

[Yitzchak Gale]

There has been a new development regarding GHC 7.8.2.

A serious bug was inadvertently included in the released 7.8.1:

https://ghc.haskell.org/trac/ghc/ticket/8978

It has to do with a bad interaction between type families
and type aliases. So it might not even affect anything
in the platform. But it does, for example, break much of
the yesod ecosystem, in a way that cannot be worked
around without breaking support for recent versions of
GHC that they still support.

Therefore, the GHC team is now planning to release 7.8.2
very shortly, and tell everyone not to use 7.8.1.
They have stated that all previous discussions
about what will be in 7.8.2 and when it might come out should
now be assumed to be talking about 7.8.3 instead:

http://www.haskell.org/pipermail/ghc-devs/2014-April/004605.html
http://www.haskell.org/pipermail/ghc-devs/2014-April/004616.html

So I think that Mark's decision that we will
"stick with 7.8.1" should be reconsidered at this point.

Thanks,
Yitz
