Please keep in mind that the Beta code can potentially become unstable or buggy at any time, so USE AT YOUR OWN RISK. You will. of course, find bugs in the more stable Officially released versions too (see the man page for a note on this). Please report new bugs to the FVWM Workers Mailing List (see below).
Development right now (10/98) is quite active, expect to see a new release "Real Soon Now".
