            Release Notes: This version brings a simple user command line interface called bdsh and delivers a task loader and application tracer. Support for the FAT file system and RAM disk block device have been added. This release significantly improves native hardware support for the ia64, ppc32, and sparc64 ports. The configuration system has been reworked and the console subsystem is now much faster. As usual, this release brings lots of bugfixes and other improvements.

                  Release Notes: This release brings a more complete and more generic port to SPARC64, reworked IRQ dispatcher and IPC notifications, a kernel test framework integrated into the kernel console, thread and task processor cycle accounting and sampling, cleaned up type dependencies, and the ability to compile by Objective C and C++ compilers. Many bugfixes and the integration of a dummy ARM32 port. This release is intended to make a checkpoint before upcoming changes in the IA-64 port, timeout subsystem, the addition of RCU synchronization, and componentization of the kernel.

                    Release Notes: This release brings support for Xen 3.0 via the new xen32 port and more virtualization via partitioning resources into separate kernel contexts. The sparc64 port has been improved so that the kernel boots on a real Sun Ultra 5 workstation. A new sparc64 boot loader and support for more Sun-specific devices was added. Finally, HelenOS is now more portable because it is C99 compliant.
