Release Notes: This version updates the kernel to 2.4.20-rc1, and a 2.4.20-pre5 kernel is also included. Booting from a USB CD-ROM should actually work now.
Release Notes: This version fixes a number of bugs in the build script, which was basically unusable in 2.0.0. Like all "letter" releases, this update affects you only if you intend to build custom versions using the build scripts.
Release Notes: This fixes a one-line bug in the build script. As usual, lettered releases differ only if you are using the build scripts to build your own customized version, and if you already have the unlettered version, you can download the "buildtree" tarball instead of the full ISO image.
