Changelog History

• v0.3.1.0 Changes

  February 23, 2020

  • ➕ Add a cabal flag to remove dependencies on finite-typelits and finitary, at the cost of the instances providing actions on finite types.

• v0.3.0.0 Changes

  February 16, 2020

  • 📦 Switch to using the groups package for the definition of the Group typeclass, 📦 splitting off the generic instances to the groups-generic package.

• v0.2.0.0 Changes

  February 14, 2020

  • ✂ Remove definition of cyclic groups. It is instead suggested to use a library which defines modular arithmetic.
    For instance: type C (n :: Nat) = Sum ( Finite n ), using the finite-typelits library.

  • CyclicEnum newtype changed to Finitely newtype, which uses Finitary instead of Bounded + Enum. This ensures that the action is by a semigroup of the right cardinality.

  • ✂ Remove Act instances for Max, Min to avoid possible overlap with user defined instances.

  • Add anti :: Group g => g -> Dual g function to construct elements in the opposite group.
    🚚 Obsoletes the Act instance for Dual (now removed).

  • ➕ Address a limitation of GHC < 8.10 with DerivingVia and MultiParamTypeClasses, by manually writing some instances.

• v0.1.0.0 Changes

  February 13, 2020

  • 🎉 Initial release.
