May 1st 2012, Calgary, Alberta, Canada and elsewhere: OpenBSD project leader Theo de Raadt (deraadt@) today announced the release of and general availability of OpenBSD 5.1, the latest version of the project's namesake operating system, via FTP, HTTP and other network distribution.
Today's OpenBSD 5.1 release is the 32nd iteration of the OpenBSD every-six-months-like-clockwork release cycle. In addition to pioneering work in operating system and network security, the project is the originator of several important components that are re-used by other operating systems, such as the OpenSSH secure shell system, the PF packet filter and its suite of related tools, the OpenBGPD and OpenNTPD network daemons, and the mandoc suite of documentation tools.
In the run-up to the general release, reports of pre-ordered CD sets, T-shirts and other OpenBSD 5.1 merchandise arriving at their destinations have trickled in from Europe and elsewhere.
Notable improvements in OpenBSD 5.1 over previous versions include
Improved hardware support, including support for numerous mobile broadband devices, various network driver improvements, improved resume functionality for USB devices
Network stack improvements include enhanced IPv6 functionality and
ipsec support in ppp and pppoe, IPv6 functionality improvements in
general, increased robustness in the IEEE 802.11 subsystem, and
various CARP improvements
A general sprinkling of improvements in network commands and
daemons, including wider routing domain support
Improved IPv6 functionality in PF, including enhanced fragment
handling, NAT64 via af-to as well as ICMP and ICMPv6 fixes, plus a
number of fixes to pfsync.
OpenSSH version 6.0 is included in OpenBSD 5.1, with a number of
fixes and enhancements.
Incremental functionality enhancements in the package handling and
package building tools, making interactions with the ports tree of
more than 7000 third-party packages even easier. In this release,
the i386 and amd64 architectures both ship with more than 7000
prebuilt binary packages ready to install, other architectures
