 - Module Structure: Add 3rd party library hook management functions. This also requires an update to all existing module_init()
 - Hash-Mode 13200 (AxCrypt): Changed the name to AxCrypt 1 to avoid confusion
 - Hash-Mode 13300 (AxCrypt in-memory SHA1): Changed the name to AxCrypt 1 in-memory SHA1
+- OpenCL Runtime: Switched default OpenCL device type on macOS from GPU to CPU. Use -D 2 to enable GPU devices.
 - Unit tests: Added Python 3 support for all of the Python code in our test framework
 - Unit tests: Fixed the packaging of test (-p) feature
