     251=== `array-0.5.1.0`
     252
     253In 0.5.0.0, one could derive Data.Array.Unboxed instances for newtype Int's, Word64's etc.:
     254
     255{{{#!hs
     256newtype N = MkN Word64
     257  deriving (IArray UArray)
     258}}}
     259
     260After https://ghc.haskell.org/trac/ghc/ticket/9220 changed the UArray role to nominal, one has to manually create instances (see http://stackoverflow.com/a/40988667/69663 for an example).
