Changelog for barbies

2.0.5.0

• Add helper class Barbies.Constraints.(&) (#46)

2.0.4.0

• Add FunctorT and DistributiveT instances for AccumT

2.0.3.1

• Compatibility changes for GHC 9.2 (Dan Dart)

2.0.3.0

• Add Barbies.Bi.bttraverse_
• Add Barbies.Bi.btfoldMap
• Fix failure to derive Constraints{B,T} for proper bi-barbies.
• Builds with ghc 9 (Fumiaki Kinoshita)

2.0.2.0

• Add Barbies.Bare.WearTwo type family to support having field-specific newtype wrappers that get applied only to the covered barbie (Lennart Spitzner).

2.0.1.0

• Add the DistributiveB class (Gergő Érdi).

2.0.0.0

• Builds with ghc 8.8, but drops support for ghc 8.0 and 8.2
• Fix failure to derive TraversableB and ConstraintsB when using a type parameter not under the functor argument.
• Fix failure to derive instances for types with arguments of kind k -> Type.
• Fix failure to derive instances where functor arg is applied under a functor.
• Derive instances for nested barbies occurring under two functors (Matthew Peddie).
• Add foldMapC and bzipWithxC (Matthew Peddie).
• Create a Barbies module, to contain wrappers, basic docs, etc. Data.Functor.Barbie contains only functor-related stuff.
• Replace ProductB by ApplicativeB, with more lax laws. Now we can derive more instances than before, since arbitrary monoids are allowed as fields of the record.
• Add Data.Functor.Transformer, operations for bi-barbies, including support for nesting.
• Add a ErrorContainer wrapper, similar to Container but for Either e.
• Remove ProductBC, since bdicts can now be defined in terms of ApplicativeB and ConstraintsB.
• Remove functions deprecated on release 1.0
• Deprecate Data.Functor.Prod, (/*) and (/*/).
• Deprecate Data.Barbie, in favor of Data.Functor.Barbie.
• Deprecate Data.Barbie.Bare, in favor of Barbies.Bare.
• Deprecate Data.Barbie.Constraints, in favor of Barbies.Constraints.

1.1.3.0

• Wear will raise a TypeError instead of getting stuck (Alex Peitsinis).

1.1.2.1

• Uploaded 1.1.2.0 was broken (missing btraverseC)

1.1.2.0

• Add traverseC (Ole Krüger).
• Fix typo in ProductB laws (thanks to Ben Radford).

1.1.1.0

• Add bmapC (Chris Penner).

1.1.0.0

• Make all classes poly-kinded (#7): a barbie can now be any type parameterised by a type (k -> Type). In particular, a (higher-kinded) barbie is a type parameterised by a barbie. Thanks to Ole Krüger.

• Add instances for functor transformers: Proxy, Const, Product, Sum and Compose (Ole Krüger).

1.0.0.0

• Replaced ConstraintsOf in ConstraintsB by AllB, which allows constraints to be given on a instead of on f a. The ClassF class lets us specify constraints on f a by doing AllB (ClassF c f) b. ConstraintsOf becomes then a type alias. Credit goes to Csongor Kiss.

• ConstraintsOf was ultimately deprecated in favour of AllBF, which is shorter and more consistent with AllB.

• Renamed ConstraintsB(adjProof) to ConstraintsB(baddDicts).

• Renamed ProofB(bproof) to ProductBC(bdicts).

• Changed the way Wear works: now wear-types need to have an extra type parameter that controls whether they are Bare or Covered. This let us remove all the "magic" that was involved, in the sense that one couldn't have instances of FunctorB, etc, for wear-types wihtout using unsafeCoerce (this was true also for handwritten instances).

• Added bsequence', a frequent specialisation of bsequence.

• Added bfoldMap.

• Added buniqC and bmempty.

• Improved the internal instance derivation mechanism. We no longer need unsafeCoerce and the code should be in general indistinguishible from hand-written instances (not currently verified).

• Fixed support for barbie-types that have additional type parameters (#5).

0.1.4.0

• Added btraverse_

• Added the trivial Void and Unit barbies

0.1.3.1

• Fixed issue on Barbie-types with strictness annotations.

0.1.3.0

• Use both Monoid and Semigroup as constraints for the Monoid instance, so that this works with ghc 8.0 to 8.4 (Fraser Murray)

0.1.2.0

• Use Monoid and not Semigroup as constraints for the Monoid instance

0.1.1.0

• Added instance Semigroup (Barbie b) to go along the Monoid instance

0.1.0.1

• Works under GHC 8.0.2, but notice one needs to use empty instance declarations, because ghc chokes on deriving clauses.

0.1.0.0 - Initial release
