Release Notes: This major release delivers many improvements that have been developed in the mainline branch since March 2011, including the deliverables from GSoC 2011. Some of the noteworthy new features are USB support, a reimplemented networking stack with full TCP support and new network drivers (including Realtek RTL8139 and Intel E1000), read-only ext2 and ISO 9660 file system support, read-write MINIX FS support, and several ported applications (GNU Binutils, PCC, MSIM).
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 version contains the new file system framework, including the VFS service, supporting libraries and an example, memory-based, file system implementation called TMPFS. This release also brings important improvements of the ia64 port as well as enhancements of the IPC subsystem.
Release Notes: This release fixes many bugs and adds new functionality to the kernel and userspace. The kernel supports graceful task destruction and cleanup, and contains reworked memory sharing and asynchronous IPC. The userspace layer was extended with textual and graphical framebuffer and console services. BSD Tetris has been ported to demonstrate the userspace capabilities of HelenOS. The AMD-64, IA-32, IA-64, MIPS-32, and PPC-32 ports are roughly equal in functionality. It comes with official documentation.
Release Notes: Userspace support for the PPC32 architecture, B+trees, a device driver interface for userspace drivers, sharing memory, AMD-64 and IA-32 framebuffer support, initial userspace PCI and keyboard drivers, an improved naming service, and many bugfixes.
