Version 1.3.141 of the DCC source is in
http://www.dcc-servers.net/dcc/source/dcc.tar.Z  and
http://www.rhyolite.com/dcc/source/dcc.tar.Z

Commercial version 2.3.141 of the DCC Reputation code is in the usual place.

The CHANGES file in
http://www.dcc-servers.net/dcc/dcc-tree/CHANGES and
http://www.rhyolite.com/dcc/dcc-tree/CHANGES and
starts with
    Fix "MTA-last" in dcc man page as suggested by Bram Grietens.
    Fix no_forced-discard typo reported by Bram Grietens.
    Fix dccm to honor `hackmc -R` and discard relay attacks.
    misc/DCC.pm, which is generated from misc/DCC.pm.in, is now very
	similar to what will probably be in SpamAssassin 3.4.
    Fix problems finding native milter library for dccm pointed out by
	Kevin A. McGrail.
    Improve documentation or help output from the nagios plugin,
	/var/dcc/libexec/dcc-nagios
    Fix bug in misc/DCC.pm in dealing with mail that already has an
	X-DCC header found and diagnosed by Herbert J. Skuhra.

dcc_learn_score probably would not help sites that have set their
DCC threshold below "many", but it seems to help the many
DCC+SpamAssassin installations that use the default "many" thresholds.
Late last year sites in Germany using SpamAssassin with DCC switched
to that new version of DCC.pm and turned on dcc_learn_score to
report mail declared spam by SpamAssassin to DCC.  Immediately after
that, server graphs for some other German DCC installations suggested
significantly improved DCC hit rates.  I theorize that there is
plenty of spam targeting mailboxes in Germany but not spam traps
in the U.S.

/var/dcc/libexec/updatedcc should automagically fetch, build, and
install the commercial or free version, depending on the .updatedcc_pfile
file, unless you have installed a version of Linux with the broken
default `sort` collating sequence since last upgrading.  If so, an
easy way to get the old updatedcc script working is to delete the
entire /var/dcc/build/dcc directory before running updatedcc.
