Changes in version 0.6.3.0

• 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.

Changes in version 0.6.2.0

• Drop support for GHCs before 7.4

• SmallArray support

• ArrayArray# based support for more efficient arrays of unlifted pointer types

• Make Array and the like instances of various classes for convenient use

• Add Prim instances for Ptr and FunPtr

• Add ioToPrim, stToPrim and unsafe counterparts for situations that would otherwise require type ascriptions on primToPrim

• Add evalPrim

• Add PrimBase instance for IdentityT

Changes in version 0.6.1.0

• 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

Changes in version 0.6

• Split PrimMonad into two classes to allow automatic lifting of primitive operations into monad transformers. The internal operation has moved to the PrimBase class.

• Fixed the test suite on older GHCs

Changes in version 0.5.4.0

• Changed primitive_ to work around an oddity with GHC's code generation on certain versions that led to side effects not happening when used in conjunction with certain very unsafe IO performers.

• Allow primitive to build on GHC 7.9

Changes in version 0.5.3.0

• Implement cloneArray and cloneMutableArray primitives (with fall-back implementations for GHCs prior to version 7.2.1)

Changes in version 0.5.2.1

• Add strict variants of MutVar modification functions atomicModifyMutVar' and modifyMutVar'

• Fix compilation on Solaris 10 with GNU C 3.4.3

Changes in version 0.5.1.0

• Add support for GHC 7.7's new primitive Bool representation

Changes in version 0.5.0.1

• Disable array copying primitives for GHC 7.6.* and earlier

Changes in version 0.5

• New in Data.Primitive.MutVar: atomicModifyMutVar

• Efficient block fill operations: setByteArray, setAddr

Changes in version 0.4.1

• New module Data.Primitive.MutVar

Changes in version 0.4.0.1

• Critical bug fix in fillByteArray

Changes in version 0.4

• Support for GHC 7.2 array copying primitives

• New in Data.Primitive.ByteArray: copyByteArray, copyMutableByteArray, moveByteArray, fillByteArray

• Deprecated in Data.Primitive.ByteArray: memcpyByteArray, memcpyByteArray', memmoveByteArray, memsetByteArray

• New in Data.Primitive.Array: copyArray, copyMutableByteArray

• New in Data.Primitive.Addr: copyAddr, moveAddr

• Deprecated in Data.Primitive.Addr: memcpyAddr
