SenderID milter のBeta0が出ていた

2008/5月中に，1.0.0を公開するつもりだったみたい。

1.0.0           2008/05/??
        Update to the latest Authentication-Results header format.
        Include SMTP AUTH status on the Sender ID Authentication-Results:
                header field and allow authenticated mail to pass.  Based
                on a patch from Adrian Havill.
        Add new command line flag "-n" which suppresses use of SPF scope
                rules while processing Sender ID.  Patch from Dick St.
                Peters.
        The rule processor can now return "none" as its own result.
        The "-r" command line flag now refers to rejection "modes" instead
                of "levels".  Also a fifth mode has been added.  Based on
                a patch from Dick St. Peters.
        Take advantage of some of the optimizations in milter v2, such
                as suppressing altogether the body I/O.
        When auto-restart is in use, have the parent wait around for the
                child and then remove its pid file so that scripts
                watching for termination can be properly synchronized.
        Feature request #SF1481668: Add new command line flag "-Q" which
                suppresses some informational logging.  Requested by
                Steve McKenna.
        Feature request #SF1491790: Add new command line flag "-c" which
                continues processing a message when its PRA could not be
                determined rather than rejecting it.
        Feature request #SF1510079: The peerlist now handles IPv6 addresses
                as well as negations.  Requested by Nick Sayer.
        Feature request #SF1681069: Add new command line flag "-B" which
                replaces NXDOMAIN replies to TXT queries with the
                "best guess" SPF record.  See
                http://www.openspf.org/FAQ/Best_guess_record for more
                information.
        Add _FFR_NH_MFROM which enables some suggested additional handling
                of the different record types within the different scopes.
                See the code for documentation.
        LIBMARID: Several fixes from Dick St. Peters, including a fix
                to "redirect" parsing, tolerance of multiple records when
                they are just different SPF versions, and addition of the
                "mfrom" spf2.0 scope to the parser.
        LIBMARID: Fix bug #1608836: Handle a/CIDR and mx/CIDR rules
                correctly.  Problem noted by John Villalovos.
