 - Made it possible to override the tuning parameters in the clients straight from JSON tuning files
 - Added OpenCL pre-processor to unroll loops and perform array-to-register promotions for compilers
   which don't do this themselves (ARM Mali) - greatly improves performance on these platforms
+- Various minor fixes and enhancements
 - Added tuned parameters for various devices (see README)
