- Added option --markov-inverse to inverse markov statistics, with the idea of reversing the order of the password candidates
- Added temperature watchdog and fanspeed readings for CPU and GPU on macOS using iokit
- Added temperature watchdog and utilization for CPU on linux using sysfs and procfs
- Added option --increment-inverse to increment masks from right-to-left instead of left-to-right
