6 [2021.mm.dd]

  • Invert dependency between comonad and distributive
  • Drop support for GHC < 8.6
  • Add Generic, Generic1 instances where possible
  • Stop exporting Control.Comonad from all the Control.Comonad.Foo modules to match style with the upcoming mtl release.
  • Add Eq(1), Ord(1), Read(1), and Show(1) instances for EnvT.

5.0.8 [2020.12.30]

  • Explicitly mark modules as Safe or Trustworthy
  • The build-type has been changed from Custom to Simple. To achieve this, the doctests test suite has been removed in favor of using cabal-docspec to run the doctests.

5.0.7 [2020.12.15]

  • Move FunctorWithIndex (TracedT m w) instance from lens. This instance depends on the indexed-traversable package. This can be disabled using the flag of the same name.

5.0.6 [2019.11.26]

5.0.5 [2019.05.02]

  • Raised the minimum semigroups version to 0.16.2. In addition, the package will only be required at all for GHCs before 8.0.
  • Drop the contravariant flag from comonad.cabal, as comonad no longer depends on the contravariant library.

5.0.4 [2018.07.01]

  • Add Comonad instances for Tagged s with s of any kind. Before the change, s had to be of kind *.
  • Allow containers-0.6.

5.0.3 [2018.02.06]

  • Don't enable Safe on GHC 7.2.

5.0.2

  • Support doctest-0.12

5.0.1

  • Revamp Setup.hs to use cabal-doctest. This makes it build with Cabal-1.25, and makes the doctests work with cabal new-build and sandboxes.

5

  • Removed module Data.Functor.Coproduct in favor of the transformers package's Data.Functor.Sum. n.b. Compatibility with older versions of transformers is possible using transformers-compat.
  • Add Comonad instance for Data.Functor.Sum.Sum
  • GHC 8 compatibility

  • instance Monoid m => ComonadTraced m ((->) m)

4.2.5

  • Added a MINIMAL pragma to Comonad.
  • Added DefaultSignatures support for ComonadApply on GHC 7.2+

4.2.4

  • Added Kenneth Foner's fixed point as kfix.

4.2.3
