- Fixed the parsing of command line options. It doesn't show two times the same error about an invalid option anymore
- Fixed the parsing of DCC2 hashes by allowing the "#" character within the user name
- Fixed the parsing of descrypt hashes if the hashes do have non-standard characters within the salt
- Fixed the output of --show when used together with the collider modes -m 9710, 9810 or 10410
- Fixed the version number used in the restore file header
