The NetBSD Project announced that NetBSD 1.6.1 has been tagged and the release engineering process has begun. NetBSD 1.6.1 is a maintenance (or patch) release for users of NetBSD 1.6, not to be confused with NetBSD-current (which will become the next major release). As a patch release, it will not be branched off the head of the CVS source tree, but instead includes all security fixes and patches applied to the 1.6 branch.
Also, Jason R Thorpe from WasabiSystems, has checked in some experimental support for RAID volumes found on ATA “RAID” controllers. These controllers are just IDE controllers with a BIOS that can configure RAID volumes, write config blocks to the disks, and do I/O to the volumes, for the purpose of booting. The OS has to implement the RAID in software, using the configuration data that is written to the disks by the BIOS.
