Revision history for dependent-sum

0.6.1.0 - 2019-08-04

• Add legacy eqTagged and compareTagged functions. Fix deprecated OrdTag synonym (it was missing the Has' Eq constraint). To upgrade from dependent-sum <0.6, you will likely need to add enable the FlexibleContexts language extension, and possible others.

0.6 - 2019-03-21

• Use constraints-extras ArgDict/Has' to define the instances of Eq, Ord, Read and Show for DSum. This obviates the need for the EqTag, OrdTag, ReadTag and ShowTag classes.

0.5.1.0

• Add mkSome and mapSome to Data.Some.
• Add GEq, GCompare, GShow, and GRead instances for Sum and Product (Except GRead (Product a b)).
• Deprecate (:=) for (:~:) from Data.Type.Equality. In GHC 7.8 and above, this is the same as (:~:). But now we no longer support earlier GHCs, so there's no point of the alias.
• Remove support for GHC 7.x.
• The git repositories for dependent-sum and dependent-sum-template are now the same, though the Haskell packages remain separate.

0.5.0.0

• Make Some a newtype with associated pattern synonyms using unsafeCoerce to avoid the GADT performance overhead. This shouldn't affect users.
• Deprecate the constructor name This in favor of Some.
• Drop support for GHC older than 8.0.
