v0.8.0.0

Changes in version 0.8.0.0

• Add resizeSmallMutableArray that wraps resizeSmallMutableArray# from
  GHC.Exts.

• New module Data.Primitive.PrimVar. This is essentially PrimArray with
  element length 1. For types with Prim instances, this is a drop-in
  replacement for MutVar with fewer indirections.

• PrimArray's type argument has been given a nominal role instead of a phantom role.
  This is a breaking change.

• Add readCharArray, writeCharArray, indexCharArray for operating on
  8-bit characters in a byte array.

• When building with base-4.17 and newer, re-export the ByteArray and
  MutableByteArray types from base instead of defining them in this
  library. This does not change the user-facing interface of
  Data.Primitive.ByteArray.

• Add keepAlive that wraps keepAlive# for GHC 9.2 and newer. It
  falls back to using touch for older GHCs.

v0.6.3.0

• Add PrimMonad instances for ContT, AccumT, and SelectT from
  transformers

• Add Eq, Ord, Show, and IsList instances for ByteArray

• Add Semigroup instances for Array and SmallArray. This allows
  primitive to build on GHC 8.4 and later.

v0.6.1.0

• Use more appropriate types in internal memset functions, which prevents
  overflows/segfaults on 64-bit systems.
• Fixed a warning on GHC 7.10
• Worked around a -dcore-lint bug in GHC 7.6/7.7
