## 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`
