Changes

0.11.0.3

  • Support GHC 9.2

0.11.0.2

  • Support GHC 9.0

0.11.0.0

  • Added makeAdaptorAndInstanceInferrable which has better inference properties, at the cost having to turn on UndecidableInstances. The tuple instances are now made by this method too.

    Please note that if you have written your own Default instances containing tuples they will no longer work, or may break in unexpected ways. For example, the following are no longer supported

    instance Default MyProfunctor (Foo, Bar) Baz
instance Default MyProfunctor Foo,  (Bar, Baz)

0.10.0.1

  • Added Data.Profunctor.Product.Examples

0.10.0.0

  • Removed ProductContravariant, AndArrow, defaultContravariantProduct, PPOfContravariant, unPPOfContravariant, cdef

  • Deprecated defaultEmpty, defaultProfunctorProduct, defaultPoint

0.9.0.0

  • Added more ProductProfunctor/SumProfunctor instances including for types in Data.Bifunctor

  • Added Data.Profunctor.Product.Adaptor which derives genericAdaptor with Generic

  • Added ability to derive Default instance with Generic

Sorry, we didn’t track changes before version 0.9.0.0
