The OpenBSD project produces a free, multi-platform 4.4BSD-based UNIX-like operating system. It emphasizes portability, standardization, correctness, proactive security and integrated cryptography.

OpenBSD has a new release every six months. Only the two most recent releases receive security and reliability fixes for the base system.

Release Flavors

  • -release: The version of OpenBSD shipped every six months.
  • -current: The development branch. Every six months, -current is tagged and becomes the next -release.
  • -stable: The -release branch, plus patches found on the errata page. Very important fixes are backported to the supported -stable branches.

OpenBSD publishes announcements and security advisories on the announcements mailing list. There’s an RSS feed for errata as well.

You can check the version that you are currently using by running:
uname -r

You can submit an improvement to this page on GitHub. This page has a corresponding Talk Page.
