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)

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
