+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](http://en.wikipedia.org/wiki/Band_(mathematics)#Rectangular_bands) `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

+description:
+ Provides a wide array of (semi)groupoids and operations for working with them.
+ .
+ A 'Semigroupoid' is a 'Category' without the requirement of identity arrows for every object in the category.
+ .
+ A 'Category' is any 'Semigroupoid' for which the Yoneda lemma holds.
+ .
+ When working with comonads you often have the @\<*\>@ portion of an @Applicative@, but
+ not the @pure@. This was captured in Uustalu and Vene's \"Essence of Dataflow Programming\"
+ in the form of the @ComonadZip@ class in the days before @Applicative@. Apply provides a weaker invariant, but for the comonads used for data flow programming (found in the streams package), this invariant is preserved. Applicative function composition forms a semigroupoid.
+ .
+ Similarly many structures are nearly a comonad, but not quite, for instance lists provide a reasonable 'extend' operation in the form of 'tails', but do not always contain a value.
+ .
+ Ideally the following relationships would hold:
+ .
+ > Foldable ----> Traversable <--- Functor ------> Alt ---------> Plus Semigroupoid
+ > | | | | |
+ > v v v v v
+ > Foldable1 ---> Traversable1 Apply --------> Applicative -> Alternative Category
+ > | | | |
+ > v v v v
+ > Bind ---------> Monad -------> MonadPlus Arrow
+ >
+ .
+ Apply, Bind, and Extend (not shown) give rise the Static, Kleisli and Cokleisli semigroupoids respectively.
+ .
+ This lets us remove many of the restrictions from various monad transformers
+ as in many cases the binding operation or @\<*\>@ operation does not require them.
+ .
+ Finally, to work with these weaker structures it is beneficial to have containers
+ that can provide stronger guarantees about their contents, so versions of 'Traversable'
+ and 'Foldable' that can be folded with just a 'Semigroup' are added.

+-- If extended to an 'Alternative' then '<!>' should equal '<|>'.
+--
+-- Ideally, an instance of 'Alt' also satisfies the \"left distributon\" law of

+-- > pure a <!> b = pure a
+--
+-- However, this variation cannot be stated purely in terms of the dependencies of 'Alt'.
+--
+-- When and if MonadPlus is successfully refactored, this class should also
+-- be refactored to remove these instances.
+--
+-- The right distributive law should extend in the cases where the a 'Bind' or 'Monad' is
+-- provided to yield variations of the right distributive law:
