Yeah; sorry about that. Until about mid-2002, hashcash changed formats twice, but there was no indication of the format version in the hashcash token itself, and I didn't know whether it would change again, or whether it would always be possible to tell what version you had just from looking at the stamp, so I invented a version number for it; hashcash.el calls for the original 1997 format version 1.0, the later version with the colons version 1.1, and what Adam called "version 0" version 1.2. As of (Adam's) version 0, hashcash tokens contain their own version number, so there's no need to change the 1.2; just add support for recognising the version number in the token. My local copy has had support for "version 1" stamps since they were announced, but I forgot to update my web site since my CVS server had a disk failure and was down at the time. I'll correct that right now: http://users.actrix.co.nz/mycroft/hashcash.el Simon: I assigned copyright to the FSF about 18 months ago, when you first asked me to. --=20 Malum est consilium quod mutari non potest -- Publilius Syrus (setq reply-to (concatenate 'string "Paul Foley " ""))
