Module documentation for 1.1.2

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

Changes

1.1.2

  • Conditionally disable Polykinds to support older versions of GHC

1.1.1

  • Increase upper bound on transformers-compat

1.1.0

  • 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
