Changelog of @hackage/base-orphans 0.7

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

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

Backported Bits, FiniteBits, Floating, Fractional, Integral, IsString, Num, Real, RealFloat, and RealFrac instances for Identity and Const (introduced in base-4.9)

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

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)

The Storable instances for Complex and Ratio are now exactly as lazy as their counterparts in base (see issue #36)

GHC 8.0 compatibility
Backported instances introduced in GHC 8.0/base-4.9 (see https://github.com/haskell-compat/base-orphans/issues/32)

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)

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

Removed all Generic and Generic1 instances. These have been moved to the generic-deriving library.

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

Storable (Complex a) instance no longer requires a RealFloat a constraint if using base-4.4 or later

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

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
