Announcing NetBSD 3.0


The NetBSD Project is pleased to announce that release 3.0 of the NetBSD operating system is now available.

NetBSD is widely known as the most portable operating system in the world. It currently supports fifty seven different system architectures, all from a single source tree, and is always being ported to more.

NetBSD 3.0 continues our long tradition with major improvements in stability, performance, networking, security, also includes support for two new platforms (iyonix and hp700), and many new peripherals.

Far reaching improvements to the network stack will not only provide better performance but also make NetBSD an excellent choice for a VPN gateway. PAM (Pluggable Authentication Modules) framework adds more flexibility to NetBSD's user management and simplifies integration into heterogeneous networks. The kernel, libraries and utilities can now handle filesystems larger than two terabytes, and support for Xen 2.0 allows hosting many virtual servers on a single machine.

About NetBSD

The NetBSD operating system is a full-featured, open source, UNIX-like operating system descended from the Berkeley Networking Release 2 (Net/2), 4.4BSD-Lite, and 4.4BSD-Lite2. NetBSD 3.0 runs on 57 different system architectures featuring 17 machine architectures across 17 distinct CPU families, and is being ported to more. The NetBSD 3.0 release contains complete binary releases for 53 different machine types, with the platforms amigappc, bebox, pc532 and playstation2 released in source form only.

NetBSD is a highly integrated system. In addition to its highly portable, high performance kernel, NetBSD features a complete set of user utilities, compilers for several languages, the X Window System, firewall software and numerous other tools, all accompanied by full source code. The NetBSD Packages Collection, pkgsrc, contains over 5,700 packages. Binary package releases for a number of platforms are currently in progress.

Major Changes Between 2.0 and 3.0

The complete list of changes can be found in the CHANGES and CHANGES-3.0 files in the top level directory of the NetBSD 3.0 release tree. Some highlights include:

Supported platforms and machines

  • A port to new platform: iyonix. The iyonix port supports the Iyonix PC, which is a desktop computer from Castle Technology, based on a 600MHz XScale 80321 processor.
  • The xen port now supports Xen 2.0, both in privileged and unprivileged mode.
  • The evbarm port has support for the TS-7200 single board computer, which is also known as the NetBSD Controlled Toaster.
  • The sgimips port now supports IP12 (Personal Iris 4D/30, 4D/35, and Indigo R3K) machines.
  • The PowerPC 601 support is added, and the prep port now supports IBM RS/6000 60P 7020-011.


  • The i386 port now supports the Enhanced SpeedStep Technology.
  • Added the statvfs(2) family of system calls.
  • Added ptm(4), Unix/98 pty multiplexor device.
  • Added swwdog(4), a software watchdog timer facility.
  • The autoconfiguration framework is rewritten for device driver LKMs.
