v0.9.1.0

Changes in version 0.9.1.0

• Make fromListN functions good consumers for list fusion.

• Add functions to improve MutVar's interoperability with IORef and STRef.

• Add createPrimArray and createByteArray.

• Add byteArrayAsForeignPtr and mutableByteArrayAsForeignPtr.

• Use copyMutableByteArrayNonOverlapping# in the implementation of copyMutableByteArray
  on sufficiently new GHCs. This does not change the contract for copyMutableByteArray.
  This function has always been documented as having undefined behavior when the slices
  overlap. However, overlaps previously were handled gracefully (with the semantics
  of C's memmove). Going forward, users who do not uphold copyMutableByteArray's
  precondition will be met with unpredictable results.

• Drop support for GHC 8.0.

v0.9.0.0

Changes in version 0.9.0.0

• Add withByteArrayContents, withMutableByteArrayContents,
  withPrimArrayContents, withMutablePrimArrayContents.

• Fix signature of keepAlive.

• Remove re-export of fromList and fromListN from Data.Primitive.Array.

• Use mutableByteArrayContents# in GHC 9.2+

• Add Prim instance for Complex.

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

• Add default definitions for the setByteArray# and setOffAddr# methods,
  so they don't need to be defined explicitly anymore.

• Add standalone sizeOfType/alignmentOfType (recommended over sizeOf/alignment)
  and Prim class methods sizeOfType#/alignmentOfType# (recommended over sizeOf#/alignment#)

• Change Show instances of PrimArray, Array, and SmallArray. These
  previously used the fromListN n [...] form, but they now used the more
  terse [...] form.

• Correct the Read instances of Array and SmallArray. These instances
  are supposed to be able to handle all three of these forms: fromList [...],
  fromListN n [...], and [...]. They had been rejected the last form, but
  this mistake was discovered by the test suite when the Show instances were
  changed.

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
