Module documentation for 1.0.9

This library provides monad morphism utilities, most commonly used for manipulating monad transformer stacks.



  • Increase upper bound on transformers-compat


  • BREAKING CHANGE: Enable PolyKinds
    • This should in theory be a non-breaking change, but due to a bug in GHC 8.0.1 and kind inference ambiguities I'm marking this as a breaking change
