Versions 7 was released in preparation for the 2.4 kernel, although the first release still used the stable 2.2 kernel. Glibc was updated to version 2.1.92, which was a beta of the upcoming version 2.2 and Red Hat used a patched version of GCC from CVS that they called "2.96". The decision to ship an unstable GCC version was due to GCC 2.95's bad performance on non-i386 platforms, especially DEC Alpha

Partly as a result of this, some CD vendors offering Red Hat Linux call it by other names. For example, Lankum.com calls it "You-Know-Who" and LinuxCD.org calls it "Blue Jacket".
