This section of the CygUtils site contains software for B20 and older Cygwin releases. It's pretty much frozen; new software is being added only to the newer sections of the site. If you're still running B20.1, I urge you to upgrade to the Cygwin CD v1.0 or newer (yes, that costs money). An alternative is to use the development snapshots (2000-Jan-05 or newer) or the v1.1 netrelease, due out sometime in 2Q2000 I think. However, you should be aware that the development snapshots are by definition unstable, although they contain many bugfixes and improvements compared to stock B20.1.
