That's a quite old release.

The kernel and libraries have performance enhancements and cluster
extensions.  For instance, Scyld added LFS (Large File Summit) support,
which was not in the 2.2 kernels or libraries of that time.  There are
hooks for the BProc system, which has changed its interface over
time.  We've written cross-compatible libraries, but only for a subset
of the functions.

There were many other bug fixes and performance enhancements we added,
but most are either now incorported in the standard package releases or
are transparent if missing.
