FYI, the test suites now appear to fail for GHC < 8. I've disabled the test suites for LTS 6.

tfausak commented 8 years ago

I'm alright with that as long as it's not a problem for Stackage.

snoyberg commented 8 years ago

It just means that we won't be able to catch semantic breakages in future release of LTS Haskell.
