Release Notes: Reliability related fixes have been made. There are also some new utilities. This release needs only one disk to work. LIBC now uses the QuickFit based allocation system, which has proven to be working quite well. This release has also passed a new stress test(runner.bin), such as repeated application launching for over 30,000 times.
