Version 1.3.25 of the DCC source is in
http://www.dcc-servers.net/dcc/source/dcc.tar.Z  and

Perhaps the most important change concerns reducing the number of
FUZ1 checksums kept in the database to reduce the load on servers.
The CHANGES file starts with:

    Fix dccproc crash when given a bogus env_From value diagnosed by
	Jeff Mincy.
    Fix greylist triple checksum in dccm and dccifd log files.
    Fix the default expiration of DCC Reputation checksums at 30 days and
	2 days unaffected by the system's amount of RAM.
    Expire FUZ1 checksums in reports that also have FUZ2 checksums.  This
	significantly reduces the size of the DCC server database.
    Remove new flood output rate limit using SO_SNDBUF because it causes some
	versions of Solaris to generate persistent EAGAIN errors for send().
    Fix at least some of the dccifd memory leak reported by Chris Mikkelson.
	It may be the same as the leak reported by Gunther Richter.
    Limit worst case DCC client delays exclusive of delays caused by waiting
	for DNS blacklists or external filters are limited to about 16 seconds.

/var/dcc/libexec/updatedcc should automagically fetch, build, and install
this version.
