We currentl have FindBugs 1.3.9 in Central and JBDS Extras.

But there's a 2.0.1.rc2 out now, as well as 2.0.0.

"Anyone currently using FindBugs 1.3.9 should find FindBugs 2.0 to largely be a drop-in replacement that offers better accuracy and performance." - http://findbugs.sourceforge.net/findbugs2.html
