OpenBSD Lifecycle (EOL)


Below you can find the life cycle for each version of operating system OpenBSD, like OpenBSD 6.1, including release dates and end of life (EOL) dates.

The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. As an example of the effect OpenBSD has, the popular OpenSSH software comes from OpenBSD.
