hashcash-1.22 provides a bug fix for a display glitch in the progress (-P) option as reported by Phil Marek. No other reason to upgrade. CHANGELOG entry: hashcash-1.22 - 08-Apr-2006 - Adam Back <adam@xxxxxxxxxxxxxxx> * fix progress display bug reported by Phil Marek. (When the progress reached 2^30 tests, it would reset the best seen). This involved multiple related bug fixes, complex thing to debug! * make percentage progress show more precision the larger the stamp, so progress is less boring. * remove some cruft from test.sh so it works again * change docs and code output to talk about partial hash preimages instead of partial collisions, as this is a more accurate description these days.
