OpenBSD Theo de Raadt has announced the release of OpenBSD 5.1. The OpenBSD 5.1 release page has a detailed list of all changes and improvements. As always, I would love for someone to write proper items about OpenBSD releases - it's outside my interests and cursory glances don't do it justice.

Been using OpenBSD since 2.something. For what I use it for (firewalls, general-purpose servers) it works well for me.

Strong points: emphasis on security, correctness, and general good design. Base system includes userland (like other BSDs, unlike Linux), so your base system won't generally break due to incompatibility between components. Best open-source firewall system (pf) there is, and other tools (OpenOSPFd and OpenBGPd) can let you replace commercial routers. Easiest-installing OS I've used. Complete, correct documentation written by folks who consider it as important as good code. Good wireless card support, at least as a client. Relatively small developer community gives precise focus. Some offshoot projects in wide use my many OS & commercial projects (OpenSSH, tmux).

Not-so-strong: Raw I/O throughput probably not world-beating (though network stack is quite good). Same with SMP implementation. Relatively small developer community means some newer hardware and features slower to be supported than on Linux or FreeBSD. Filesystem size limited by RAM in current implementation (and no "advanced" options like ZFS or HAMMER). Some Linux-oriented 3rd-party software breaks (not OpenBSD's fault, but something to consider), though "classic" Unix tools and those with portability in mind typically run just fine. Limited virtualization options as host OS. Community can be hostile to those who don't ask intelligent questions or who don't RTFM.

I probably left some things out. But bottom line, it's a high-quality, reliable OS that is the right tool for some (many?) jobs. If I were an open-source developer, I'd test on OpenBSD as a QC measure.
