Changes

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
