[Dovecot] Which dovecot-antispam with dovecot 2?

Hi

I'm a little confused as there are two repos for the dovecot-antispam plugin. Eugene's hg repo is explicitly labeled "for Dovecot 2", but the Johannes' git repo has commits later in date:

hg: http://wiki2.dovecot.org/Plugins/Antispam git: http://git.sipsolutions.net/?p=dovecot-antispam.git

I guess the unrelease hg code ist the one for Dovecot 2, but what is Eugene's 1.4 code for?

Thanks!
