# Changelog for [`deepseq` package](http://hackage.haskell.org/package/deepseq)

## 1.4.0.0  *Dec 2014*

  * Bundled with GHC 7.10.1
  * 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 ()

  * New `NFData` instances for `base` types:

     - `Control.Applicative.Const`
     - `Control.Applicative.ZipList`
     - `Control.Concurrent.ThreadId`
     - `Data.Functor.Identity.Identity`
     - `Data.Monoid.{Dual,First,Last,Any,All,Sum,Product}`
     - `Data.Ord.Down`
     - `Data.Proxy.Proxy`
     - `Data.Typeable.Internal.TyCon`
     - `Data.Typeable.Internal.TypeRep`
     - `Data.Unique.Unique`
     - `Data.Void.Void`
     - `GHC.Fingerprint.Type.Fingerprint`
     - `Numeric.Natural.Natural`
