5.1

• The remaining orphan instances in Data.Traversable.Instances have been replaced in favor of the orphan instances from transformers-compat-0.5.
• The documentation now states laws that instances of Apply are expected to uphold.
• doctest-0.11 support
• Fixed compilation of tests with stack

5.0.1

• transformers-compat 0.5 support
• Removed some redundant constraints.
• GHC 8 support

5.0.0.4

• doctest 0.10 support

5.0.0.2

• Bugfix for GHC 7.4. PolyKinds on 7.4 cause all sorts of haskell interface file errors. One of the #if guards that turned it off on 7.4 was missing and has been fixed.

5.0.0.1

• Added the CHANGELOG to the distribution so that hackage can link to it in the haddocks.

5

• Absorbed Data.Bifunctor.Apply, Data.Semigroup.Bifoldable and Data.Semigroup.Traversable from bifunctors.
• This caused us to pick up a dependency on tagged.
• Exiled Data.Semifunctor.*, Data.Semigroupoid.Product and Data.Semigroupoid.Coproduct to semigroupoid-extras.
• This let us open up to older versions of GHC again.
• Set an explicit fixity for -<- and ->-.

4.5

• Major changes to the API to support PolyKinds and DataKinds. This necessarily shuts off GHC <= 7.4.
• Orphan instances have moved upstream into a common base-orphans package.

4.3.1

• Added asum1 to Data.Semigroup.Foldable.

4.3.0.1

• Support for 'ConstrainedClassMethods' is currently required for GHC HEAD.

4.3

• Added missing instances for ExceptT. Obtain it via transformers-compat if need be for old transformers versions.
• Several Bind and Apply instances now require somewhat more minimal contexts.

4.2

• Backported Foldable/Traversable instances from lens

4.1

• Foldable1/Traversable1 for tuples

4.0.4

• contravariant 1.0 support.

4.0.3

• Added flags to provide unsupported cabal sandbox build modes.

4.0.1

• Fixed bitrot in the Data.Functor.Extend documentation.
• Fixed warnings on GHC 7.8.1rc2 caused by importing Control.Monad.Instances.

4.0

• Merged in the contents of the groupoids and semigroupoid-extras packages.

3.1

• Added the rectangular band Semigroupoid for (,). Would that make it a Bandoid?

3.0.3

• Claim to be Trustworthy where necessary

3.0.2

• Tightened the upper bounds slightly to enable PVP compliance while retaining a flexible development cycle.
• Raised the upper bound on contravariant.

3.0.1

• Removed upper bounds relative to my other packages
• Refactored directory layout
