## 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

 * Efficient block fill operations: `setByteArray`, `setAddr`

## Changes in version 0.4.1

 * New module `Data.Primitive.MutVar`

## Changes in version 0.4.0.1
