Ok, it's been about a month now since Justin left us to our own devices,
and it's time for my first release announcement.

There's a complete changelog in the distribution, but here are some
highlights:

* CHECK method added to the spamc/spamd protocol, and the '-c' flag to
spamc
* Implemented method to place actual score of message in rewritten
subject line
* Completely revamped the autowhitelisting stuff -- it's now recommended
that AWL be used again; also enabled AWL in spamassassin.
* A number of NoMailAudit/email parsing issues cleared up
* Fixed some major problems with common phrase checking and scoring
* Lots of rule fixes
* Lots of new scores for new and old rules

This new release also features scores allocated by the new GA of my own
design (well, based on jm's original).  Annecdotal evidence of running
my GA vs JM's on the same data set shows mine to do a somewhat better
job of optimization, and in a much shorter time (plus mine uses MPI to
spread load across multiple CPUs).  Now, it remains however to be seen
whether or not the new scores work as well -- the main problem being the
dataset used to feed the GA.  Justin had a pretty good corpus of spam
and nonspam emails (along with many false positives, etc) which he used
to use to generate scores from.  In the transition, we've had one or two
issues with getting a sufficiently good replacement archive up and
running -- I have hand-examined the scores output but the GA and they
actually look pretty decent, but please let me know if they look like
they're misbehaving in a big way.  I know that these scores work better
on the corpus than the old scores, but I don't know if this corpus is as
good as the old one.  It's larger, but it might not be better.

Thank you very much to everyone who has helped out in keeping things
going during the changeover in maintainership, and thanks also to
everyone who has contributed to this release, in bug reports, with code,
with new rules, or just in discussion on this list.  We're continuing to
refine the package and make it better and better.  The focus for 2.2
development will probably be on performance increases and refinement of
the rules (once bugzilla #47 is cleared).

PS I'm not sure how long it'll take the changes to propagate on
www.spamassassin.org, but they should be there before long.  If you're
desperate, you can get the release from CVS under the
spamassassin_release_2_1_0 tag.  New RPMs are available too from
http://www.hughes-family.org/spamassassin/
