Changes in next [????.??.??]

  • Drop support for pre-8.0 versions of GHC.

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:
  • 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]

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]

    • 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]
