cabal: Failed to build rest-rewrite-0.1.1

5f71ee2 already added the necessary bound on hashable. Could you publish it as a Hackage revision?

Thanks for the report, and sorry for the delay. I've uploaded a new version of REST with some additional changes, including increasing the upper bound. New version is here: https://hackage.haskell.org/package/rest-rewrite-0.2.0.
