- Reduce max. number of allowed function calls per rule from 256 to 32 to save GPU memory
- Status display shows what's the base and modifier keyspace currently in use
- Added a workaround for some OpenCL kernel to compile with amd-gpu-pro
- Added hardware management support (temperature, clocks, fans) for AMD-GPU-PRO driver
- Added support for --powertune-enable for AMD-GPU-PRO driver
- Added option --keep-guessing to continue cracking hashes even after they have been cracked (to find collisions)
- Fixed a bug when cracking a large salted hashlist: If a word is rejected this produces so high CPU load that cracking process doesn't start
