Highlights: 0) don't forget that the distro
Update (1/Jul/2002): I have since decided to faithfully post on the SpamBouncer freshmeat page about all the updates I learn of from the upstream page, to compensate for the broken updates list. There have been 2 more updates since the one originally mentioned here, and all the three were published on freshmeat. Subscribe to the project's update notification mechanism on freshmeat, and you'll learn about the updates as soon as I do (typically some 3 days later down from their release date).
Update (4/Jul/2004): due to personal reasons, last half a year I couldn't make up with the SB updates tracking. Hopefully, today it's back to normal.
