Version 0.3.1.0 (2023-01-24)

• Bumping of version bounds, and support for GHC 9.4 and GHC 9.6. Now requires ghc-tcplugin-api 0.9 or above.

Version 0.3.0.0 (2021-09-01)

• Add the (||) constraint disjunction mechanism, with

dispatch :: ( c || d ) => ( c => r ) -> ( d => r ) -> r

This allows users to select between two different constraints. This is more general than ifCt, as it allows extra constraints in the fallback branch.

• Implement IfCt, ifCt in terms of (||) and dispatch. IfCt becomes a type synonym, which means that it no longer bundles ifCt.

Version 0.2.1.1 (2021-08-31)

• Minor documentation improvements.

Version 0.2.1.0 (2021-08-31)

• Require ghc-tcplugin-api >= 0.5.1.0.

Version 0.2.0.0 (2021-08-31)

• Add a type family IsSat :: Constraint -> Bool that computes whether a type-family is satisfied in the current context.

• Rename IfCt to IfSat.

Version 0.1.0.0 (2021-08-30)

Initial release.
