v1.1 is not working on dovecot 0.8.x anymore, the plugins-structure has changed to classes. Would you be so kind to provide an updated version for newer versions of roundcube?

Actually its very simple:

class rcube_dovecotpfd_password { function save($currpass, $newpass) {

}

instead of:

function password_save($currpass, $newpass)

Thanks a lot!
