Changelog for deepseq package

1.4.5.0

• Add GNFData for URec This will enable deriving NFData instances for unboxed types

1.4.4.0 Sep 2018

• Bundled with GHC 8.6.1

• Add NFData instance for MaskingState (#38)

• Define the NFData instances for TypeRep and TyCon on all supported versions of base, not just 4.8 and later (#40)

1.4.3.0 Apr 2017

• Bundled with GHC 8.2.1

• Drop support for GHC 7.0 & GHC 7.2

• Changed strictness behavior of generic NFData instances for constructor-less data types. Before, a generic rnf implementation would always error on a data type with no constructors. Now, it will force the argument, so if the argument is a diverging computation, a generic rnf implementation will actually trigger the diverging computation. (#19)

• Add new rwhnf function defined as rwhnf !_ = () (#3)

• Add (<$!!>) :: (Monad m, NFData b) => (a -> b) -> m a -> m b (#13)

• Add NFData1 and NFData2 type classes (#8)

• Add NFData instance for Down for base versions prior to base-4.6.0 which didn't yet export it via Data.Ord (#28)

• Add NFData instance for Foreign.C.Types.CBool (#33)

• Add NFData instance for Ordering (#25)

• Add NFData1 and NFData instances for Data.Functor.{Compose,Sum,Product} (#30)

• Add NFData, NFData1, and NFData2 instances for (:~:) and (:~~:) from Data.Type.Equality (#31)

1.4.2.0 Apr 2016

• Bundled with GHC 8.0.1

• New instances for types provided by semigroups prior to base-4.9 (i.e. NonEmpty, Min, Max, Arg, Semigroup.First, Semigroup.Last, WrappedMonoid, and Option) (#11)

• New instances for Ptr and FunPtr (#10)

• New instances for IORef, STRef, and MVar (#6)

• New instance for ExitCode (#4)

• New instances for CallStack and SrcLoc

• Make NFData (Proxy a) instance poly-kinded

1.4.1.2 Aug 2015

• Avoid the broken combination of GHC-7.2 with array>=0.4 (#7)

1.4.1.1 Mar 2015

• Bundled with GHC 7.10.1
• Drop redundant ghc-prim dependency

1.4.1.0 Mar 2015

• Drop redundant constraints from a few NFData instances (if possible for a given base version)

1.4.0.0 Dec 2014

• Switch to Generics based DefaultSignature rnf method implementation (based on code from deepseq-generics)

  Compatibility Note: if you need the exact default-method semantics of deepseq prior to 1.4, replace occurences of

  instance NFData XYZ

  by

  instance NFData XYZ where rnf x = seq x ()

  • Control.Applicative.Const

  • Data.Ord.Down
  • Data.Proxy.Proxy
  • Data.Typeable.Internal.TyCon
