## Changes in 0.7 [2018.03.08]
- Backported new instances from GHC 8.4/`base-4.11`
* `Alternative` instance for `ZipList`
* `Data` instance for `IntPtr` and `WordPtr`
* `Num`, `Functor`, `Applicative`, `Monad`, `Semigroup`, and `Monoid`
instances for `Data.Ord.Down`
* `MonadFail`, `Semigroup`, and `Monoid` instances for strict `ST`
## Changes in 0.6 [2017.04.10]
- Backported new instances from GHC 8.2/`base-4.10`
(see https://github.com/haskell-compat/base-orphans/issues/39):
* `Data` instance for `Const`
* `Eq1`, `Ord1`, `Read1`, and `Show1` instances for `NonEmpty`
* `Semigroup` instances for `IO`, `Event`, and `Lifetime`
- Backported `Typeable` instances for `(:+:)`, `(:*:)`, `(:.:)`, `M1`, `Rec1`,
`ArrowMonad`, `Kleisli`, `WrappedArrow`, `WrappedMonad`, and `Any` on GHC
7.6 and earlier
- Backported `Data` instances for `(:+:)`, `(:*:)`, `(:.:)`, `M1`, and `Rec1`
on GHC 7.6 and earlier
## Changes in 0.5.4
- Backported `Bits`, `FiniteBits`, `Floating`, `Fractional`, `Integral`,
`IsString`, `Num`, `Real`, `RealFloat`, and `RealFrac` instances for
`Identity` and `Const` (introduced in `base-4.9`)
## Changes in 0.5.3
- Backported `Alternative`, `MonadPlus` and `MonadZip` instances for `U1` and
`Proxy`, and made the `Functor`, `Foldable`, `Traversable`, `Alternative`,
and `Monad` instances for `U1` lazier to correspond with `base-4.9`
## Changes in 0.5.2
- Backported `Enum`, `Bounded`, `Ix`, `Functor`, `Applicative`, `Monad`,
`MonadFix`, `MonadPlus`, `MonadZip`, `Foldable`, `Traversable`, and
`Data` instances for datatypes in the `GHC.Generics` module (introduced in
`base-4.9`)
## Changes in 0.5.1
- 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
- GHC 8.0 compatibility
- Backported instances introduced in GHC 8.0/`base-4.9`
(see https://github.com/haskell-compat/base-orphans/issues/32)
## Changes in 0.4.5
- Import `Control.Monad.Instances` (which exports `Functor` and `Monad`
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
- Fix build on OSes where `HTYPE_DEV_T = Int32` (e.g., OS X)
## Changes in 0.4.2
- `Functor` instances for `Handler`
- `Functor`. `Applicative`, `Alternative`, and `MonadPlus` instances for
`ArrowMonad`
- Expose `Read` and `Show` instances for `Down` on GHCs before 7.8
- `Bits`, `Bounded`, and `Integral` instances for `CDev`
## Changes in 0.4.1
- Fixed imports on GHC < 7.8 on Windows
## Changes in 0.4.0
- Removed all `Generic` and `Generic1` instances. These have been moved to the
`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`
* `U1`, `Par1`, `Rec1`, `K1`, `M1`, `(:+:)`, `(:*:)`, `(:.:)`, `Arity`,
`Associativity`, and `Fixity` from `GHC.Generics`
## Changes in 0.2.0
- Drop GHC 6.12 (and `base-4.2.0.0`) compatibility
- Fix Windows, GHCJS build
- `Read` instance for `Fixed`
- `Applicative` instances for strict and lazy `ST`
- `Typeable` instance for `SampleVar`
- `Applicative` and `Alternative` instances for `ReadP` and `ReadPrec`
- `Typeable` instance for `KProxy`
- `Typeable` instances for more data types in `GHC.`-prefixed modules
- `Generic` instances for `Arity`, `Associativity`, and `Fixity` from
the `GHC.Generics` module
- Corrected the `Generic` instance for `(:*:)` to work around GHC bug #9830
