Changes

4.3.1

Compatibility with GHC 8.4.x: added Semigroup (End r) instance.

4.3

Compatibility with GHC 8.0.x
Dropped incomplete instance for Algebra r (Map a b) instance
Restructured Ring hierarchy (Thanks @dfoxfranke!)
Added DecidableNilpotence class (Thanks @dfoxfranke!)

4.2

Support for nats version 1 and base 4.8’s version of Numeric.Natural. This required monomorphizing some stuff to Natural, but that is more accurate than the previous hack anyways.

4.1

Added Euclidean domains and the field of fractions.

4.0

Compatibility with GHC 7.8.x
Removed keyed and representable-tries dependencies

3.0.2

Started CHANGELOG
