##
- Fixed both false negative and false positive result in -m 3000 in -a 3 (affected only NVIDIA GPU)
- Fixed buffer overflow in -m 1800 in -O mode which is optimized to handle only password candidates up to length 15
- Fixed incorrect maximum password length support for -m 400 in optimized mode (reduced from 55 to 39)
- Fixed internal access on module option attribute OPTS_TYPE_SUGGEST_KG with the result that it was unused
- Fixed invalid handling of outfile folder entries for -m 22000
