• Fix #30

0.7 August 26th 2018

• Solve "known" type-level Booleans, also inside If (GHC 8.6+)

0.6 September 14th 2018

• Move KnownNat2 instances for Div and Mod from ghc-typelits-extra to ghc-typelits-knownnat

0.5 May 9th 2018

• Fix Inferred constraint is too strong #19

0.4.2 April 15th 2018

0.4.1 March 17th, 2018

• Add support for GHC 8.4.1

0.4 January 4th, 2018

• Add partial GHC 8.4.1-alpha1 support
• Drop singletons dependency #15
  • KnownNatN classes no longer have the KnownNatFN associated type family

0.3.1 August 17th 2017

• Fix testsuite for GHC 8.2.1

0.3 May 15th 2017

• GHC 8.2.1 support: Underlying representation for KnownNat in GHC 8.2 is Natural, meaning users of this plugin will need to update their code to use Natural for GHC 8.2 as well.

0.2.4 April 10th 2017

• New features:
  • Derive constraints for unary functions via a KnownNat1 instance; thanks to @nshepperd #11
  • Use type-substituted [G]iven KnownNats (partial solve for #13)

0.2.3 January 15th 2017

• Solve normalised literal constraints, i.e.:
  • KnownNat (((addrSize + 1) - (addrSize - 1))) ~ KnownNat 2

0.2.2 September 29th 2016

• New features:
  • Derive smaller constraints from larger constraints when they differ by a single variable, i.e. KnownNat (a + b), KnownNat b implies KnownNat a.

0.2.1 August 19th 2016

• Fixes bugs:
  • Source location of derived wanted constraints is, erroneously, always set to line 1, column 1

0.2 August 17th 2016

• New features:
  • Handle GHC.TypeLits.-
  • Handle custom, user-defined, type-level operations
  • Thanks to Gabor Greif (@ggreif): derive smaller from larger constraints, i.e. KnownNat (n+1) implies KnownNat n

0.1.2

• New features: Solve "complex" KnownNat constraints involving arbitrary type-functions, as long as there is a given KnownNat constraint for this type functions.

0.1.1 August 11th 2016

• Fixes bug: panic on a non-given KnownNat constraint variable

0.1 August 10th 2016

• Initial release
