Changes in version 0.13.0.0

• mkType from Data.Vector.Generic is deprecated in favor of Data.Data.mkNoRepType
• The role signatures on several Vector types were too permissive, so they have been tightened up:

  • The role signature for Data.Vector.Mutable.MVector is now type role MVector nominal representational (previously, both arguments were phantom). #224

  • The role signature for Data.Vector.Primitive.Vector is now type role Vector nominal (previously, it was phantom). The role signature for Data.Vector.Primitive.Mutable.MVector is now type role MVector nominal nominal (previously, both arguments were phantom). #316

  • The role signature for Data.Vector.Storable.Vector is now type role Vector nominal (previous, it was phantom), and the signature for Data.Vector.Storable.Mutable.MVector is now type role MVector nominal nominal (previous, both arguments were phantom). #235

    We pick nominal for the role of the last argument instead of representational since the internal structure of a Storable vector is determined by the Storable instance of the element type, and it is not guaranteed that the Storable instances between two representationally equal types will preserve this internal structure. One consequence of this choice is that it is no longer possible to coerce between Storable.Vector a and Storable.Vector b if a and b are nominally distinct but representationally equal types. We now provide unsafeCoerce{M}Vector and unsafeCast functions to allow this (the onus is on the user to ensure that no Storable invariants are broken when using these functions).

• Methods of type classes Data.Vector.Generic.Mutable.MVector and Data.Vector.Generic.Vector use concrete monads (ST, etc) istead of being polymorphic (PrimMonad, etc). #335. This makes it possible to derive Unbox with:
  • GeneralizedNewtypeDeriving
  • via UnboxViaPrim and Prim instance
  • via As and IsoUnbox instance: #378
• Add MonadFix instance for boxed vectors: #312
• Re-export PrimMonad and RealWorld from mutable vectors: #320
• Add maximumOn and minimumOn: #356
• The functions scanl1, scanl1', scanr1, and scanr1' for immutable vectors are now defined when given empty vectors as arguments, in which case they return empty vectors. This new behavior is consistent with the one of the corresponding functions in Data.List. Prior to this change, applying an empty vector to any of those functions resulted in an error. This change was introduced in: #382
• Change allocation strategy for unfoldrN: #387

• Add readMaybe: #425
• Add groupBy and group for Data.Vector.Generic and the specialized version in Data.Vector, Data.Vector.Unboxed, Data.Vector.Storable and Data.Vector.Primitive. #427
• Add toArraySlice and unsafeFromArraySlice functions for conversion to and from the underlying boxed Array: #434
