        NOTE: During the development cycle for this release, SourceForge
                changed their bug numbering system.  Bug numbers are recorded
                here as they were generated by the current system at the time
                they were filed.  The older ones (prefixed "SF") have since
                been renumbered or may no longer be in the system.
        Feature request #169: Discontinue libxml2 support in the reputation
                code.
        Feature request #174: Drop internal libstrl implementation.
        Feature request #175: Discontinue support for libdkimrep.
        Feature request #176: Update to the final REPUTE RFCs.
        Activate _FFR_REDIRECT.
        Fix bug #178: Add support for "dmarc" as an authentication method
                (though it hasn't been formally registered yet) and fix
                a minor Authentication-Results parsing problem.
        Fix bug #179: Correct handling of SignatureTTL.
        Fix bug #180: Drain results object when doing a DB walk of a postgresql
                table.
        Fix bug #182: Add an Authentication-Results header field even for
                messages with no valid From: field or a fatal structural
                violation.
        Teach dkimf_db_walk() about LDAP soft starting, and don't escape the
                forced "*" when walking.  Also handle incorrect attribute
                counts without causing an assertion failure.
        Call dkimf_config_free() on shutdown so that all DBs get properly
                closed and everything gets deallocated.
        LIBOPENDKIM: Fix bug #168: Report an unresolved CNAME for ADSP records
                as simply absent.
        LIBOPENDKIM: Add DKIM_LIBFLAGS_REQUESTREPORTS to request that an
                "r=y" tag be added to signatures, per RFC6651.
        TOOLS: Fix boundary condition in opendkim-testmsg.
        DOCS: Feature request #168: Improve documentation of signature
                verification failure debugging features.
        DOCS: Feature request #172: Describe socket selection procedure in
                detail, and mention selinux command to get set up.
