Estel, I do not think it is that dramatic at the moment, the fix could be as simple as removing the config file setting on the call to john and adding sudo to the call of john, which the new version now seems to require. I will do some testing and revert back soon. Just managed to mess up my device installation with my upgrade to PR 1.3.1, so still trying to get my normal development environment back . Edit: Confirmed the fix described above in the john.sh script . Back to working basic john functionality (ie. 8 characters/numbers only as described in first post). This is obviously an area of future tweaks/development.
