- OpenBSD 4.4 RELEASED -------------------------------------------------

Nov 1, 2008.

We are pleased to announce the official release of OpenBSD 4.4.
This is our 24th release on CD-ROM (and 25th via FTP). We remain
proud of OpenBSD's record of more than ten years with only two remote
holes in the default install.

As in our previous releases, 4.4 provides significant improvements,
including new features, in nearly all areas of the system:

- New/extended platforms:
o OpenBSD/sparc64.
Fujitsu's SPARC64-V, SPARC64-VI and SPARC64-VII processors are supported
now, which means that many of the PRIMEPOWER machines and the SPARC
Enterprise M4000/M5000/M8000/M9000 work now.
Sun's UltraSPARC VI processors are supported now. Many of Sun's
mid-range and high-end servers with these processors or UltraSPARC III
and UltraSPARC III+ processors work now.
Sun's UltraSPARC T1 and UltraSPARC T2 processors are supported now,
which means the sun4v architecture is now supported and machines like
the SPARC Enterprise T1000 and SPARC Enterprise T5220 work now.
o OpenBSD/socppc.
For machines based on the Freescale MPC8349E
System-on-Chip (SoC) platform that use Das U-Boot as a boot loader.
o OpenBSD/landisk: added shared libraries support.
