 - The `Storable` instances for `Complex` and `Ratio` are now exactly as lazy
   as their counterparts in `base` (see issue
   [#36](https://github.com/haskell-compat/base-orphans/issues/36))

## Changes in 0.5.0

   (see https://github.com/haskell-compat/base-orphans/issues/32)

   instances for `(->) r`, and `Functor` instances for `(,) a` and `Either a`)
   on GHCs before 7.6. This ensures that these instances will always be in
   scope, and you won't have to import a module which is deprecated on recent
   GHC releases.
 - Fix build on GHC HEAD (again)

## Changes in 0.4.4
 - Fix build on GHC HEAD

## Changes in 0.4.3

 - `Functor`. `Applicative`, `Alternative`, and `MonadPlus` instances for
   `ArrowMonad`

 - `Bits`, `Bounded`, and `Integral` instances for `CDev`

## Changes in 0.4.1

   `generic-deriving` library.

## Changes in 0.3.3
 - `Typeable` instances for `(~)`, `Any`, `Constraint`, `CSigset`, `Handler`,
   `Opaque`, `SPEC`, and every promotable data constructor in `base`

## Changes in 0.3.2
 - `Storable (Complex a)` instance no longer requires a `RealFloat a`
   constraint if using `base-4.4` or later

## Changes in 0.3.1
 - `Functor`, `Applicative`, and `Monad` instances for `First` and `Last`

## Changes in 0.3.0
 - `Show` instance for `Fingerprint`
 - `Data.Orphans` is now `Trustworthy`
 - Backported the `Generic` and `Generic1` instances available in `base-4.7.0.0`
   to GHC 7.2, 7.4, and 7.6, namely
   * `Const`, `WrappedMonad`, and `ZipList` from `Control.Applicative`
   * `WrappedArrow` from `Control.Category`
   * `All`, `Any`, `Dual`, `Endo`, `First`, `Last`, `Product`, and `Sum` from
     `Data.Monoid`

   the `GHC.Generics` module
