Changes

Version 2.2.1

  • Actually export Imperial units, along with bugfixes (thanks to @Bebere).
  • Export Eurocard units (thanks to @mlang).

Version 2.2

  • Add support for new PlaneAngle and SolidAngle dimensions, thanks to @gittywithexcitement.

Version 2.1.0.1

  • Update .cabal file to export Data.Units.Astronomical.

Version 2.1

  • Add support for Imperial and astronomical units, thanks to @Bebere.

Version 2.0.1.1

  • Drop 7.8 support, fixing warnings on 8.0.

Version 2.0.1

  • Added the universal gravitational constant, thanks to @hesiod.

Version 2.0.0.1

  • Typos in documentation. Thanks to Doug Burke for a pull request!

Version 2.0

  • Full re-organization of modules.
  • Addition of US customary units, CGS units, and a few other gubbins.

Version 1.1

  • Added si parser.
  • Moved DefaultUnitOfDim instances from SI.MonoTypes to SI.Mono. This allows client code to import the monomorphic types without getting these instances. But, it may mean that your imports have to change.

Version 1.0.1

  • Added derived SI units.
  • Added British-spelled synonyms for SI units.

Version 1.0

  • First release, contains implementations for SI.
