## Changes in 0.9.2 [2024.04.30]
- Backport new instances from GHC 9.10/`base-4.20`:
* `Fractional`, `RealFrac`, `Floating`, and `RealFloat` instances for `Compose`
## Changes in 0.9.1 [2023.10.11]
- Backport new instances from GHC 9.8/`base-4.19`:
* `Eq` and `Ord` instances for `SChar`, `SNat`, and `SSymbol`
* `Enum`, `Bounded`, `Num`, `Real`, and `Integral` instances for `Compose`
## Changes in 0.9.0 [2023.03.05]
- Adapt to recent changes to `Down` instances:
* The `Bounded` instance for `Down` was changed in `base-4.15.0.0` to swap
the values of `minBound` and `maxBound` for the underlying type. This
change has now been propagated to `base-orphans`.
* The `Enum` instance for `Down` was removed in `base-4.15.0.0`, but a
different version of the instance was added back in `base-4.18.0.0`, where
`succ` and `pred` are swapped. We have changed the backported version of
this instance in `base-orphans` to match the behavior of the instance
added in `base-4.18.0.0`.
* The `Integral` instance for `Down` was removed from `base` entirely in
`base-4.15.0.0`. We have finally removed it from `base-orphans` in this
release, as it actively makes it more difficult to define the
aforementioned `Enum` instance.
## Changes in 0.8.8.1 [2023.03.05]
- Fix GHC 9.4 build error that was accidentally introduced in
`base-orphans-0.8.8`.
## Changes in 0.8.8 [2023.03.05]
- Backport new instances from GHC 9.6.1/`base-4.18.0.0`:
* `Functor` instances for the `(,,,,) a b c d`, `(,,,,,) a b c d e`, and
`(,,,,,) a b c d e f` tuple types.
* `Eq` and `Ord` instances for `Generically1`
## Changes in 0.8.7 [2022.08.11]
- Backport new instances from GHC 9.2.2/`base-4.16.1.0`:
* `Ix` instances for various integral types in `Foreign.C.Types`,
`Foreign.Ptr`, and `System.Posix.Types`. For a complete list of such types,
see https://gitlab.haskell.org/ghc/ghc/-/merge_requests/7385.
- Backport a bugfix for the `Ord1 Down` instance from GHC 9.4/`base-4.17` such
that it now uses reverse sort order.
## Changes in 0.8.6 [2021.10.29]
- Backport `Eq`, `Ord`, `Bounded`, `Enum`, and `Ix` instances for `Solo`,
introduced in GHC 9.2/`base-4.16`
- Remove the backported `Eq1` and `Ord1` instances for `Fixed` that were
introduced in `base-orphans-0.8.5`. While these briefly appeared in a
release candidate version of GHC 9.2.1, they were ultimately removed from
the final 9.2.1 release. This release of `base-orphans` synchronizes with
that change.
## Changes in 0.8.5 [2021.08.29]
- Backport new instances from GHC 9.2/`base-4.16`
* `Eq1`, `Read1`, and `Show1` instances for `Complex`
* `Eq1` and `Ord1` instances for `Fixed`
* `Eq{1,2}`, `Ord{1,2}`, `Show{1,2}`, and `Read{1,2}` instances for `(,,)`
and `(,,,)`
* `Semigroup` and `Monoid` instances for `Data.Functor.Product` and
`Data.Functor.Compose`
## Changes in 0.8.4 [2020.12.09]
- Backport the `Ord` instances for `TyCon` and `TypeRep` to be available on
GHC 7.0.
## Changes in 0.8.3 [2020.09.30]
- Backport new instances from GHC 9.0/`base-4.15`
* `MonadFix` and `MonadZip` instances for `Complex`
* `Ix` instances for tuples of size 6 through 15
## Changes in 0.8.2 [2020.01.27]
- Backport new instances from GHC 8.10/`base-4.14`
* `Bits`, `Bounded`, `Enum`, `FiniteBits`, `Floating`, `Fractional`,
`Integral`, `Ix`, `Real`, `RealFrac`, `RealFloat` and `Storable` instances
for `Data.Ord.Down`
* `Functor`, `Applicative`, `Monad`, `Alternative`, and `MonadPlus` instances
for `Kleisli`
* `Functor`, `Applicative`, and `Monad` instances for
`(,,) a b` and `(,,,) a b c`
* `Data` instances for `WrappedArrow` and `WrappedMonad`
* `Data` and `IsList` instances for `ZipList`
* `TestEquality` instance for `Compose`
- Backport the `Typeable (() :: Constraint)` instance to be available on
GHC 7.8.
## Changes in 0.8.1 [2019.03.25]
- Ensure that the test suite passes non-negative numbers to `Bits` methods
that require them, such as `bit`, `setBit`, `clearBit`, `complementBit`,
and `testBit`.
## Changes in 0.8 [2018.07.02]

- `Monoid` instances for `U1`, `Par1`, `Rec1`, `K1`, `M1`, `(:*:)`, and `(:.:)`
* `Foldable` and `Traversable` instances for `Data.Monoid.Alt`
* `MonadFix`, `MonadZip`, `Data`, `Foldable`, `Traversable`, `Eq1`, `Ord1`,
`Read1`, and `Show1` instances for `Data.Ord.Down`
## 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]

`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

`base-4.9`)
## Changes in 0.5.1
