0.6.1

• Added covariant Day convolution. It isn't contravariant, but it is inspired by the contravariant construction.

0.5.1

• transformers 0.4 compatibility

0.5

• Added (>$)
• Added instances for GHC.Generics

0.4.4

• Fixed compatibility with GHC 7.7 and tightened Safe Haskell support.

0.4.1

• Added Day convolution under Data.Functor.Contravariant.Day.

0.3

• Added Backwards and Reverse instances for transformers 0.3
• Added instance (Functor f, Contravariant g) => Contravariant (Compose f g). (This is non-canonical, but is necessary to support other packages.)
• Added Functor instances to ComposeFC and ComposeCF for use when modeling phantom type parameters caused mixing Functor + Contravariant.
