Issue #2 resolved
There is no issue tracker on hackage for monad-parallel, so I report this here:
The transformers upper bound is breaking stackage nightly for GHC 8.0.1:
transformers: needed (>=0.2 && <0.5), 0.5.2.0 found (latest applicable is 0.4.3.0) needed for package monad-parallel-0.7.2.1
Is it possible to lift this bound?
