Yesterday, marking the 25th anniversary of the OpenBSD project, its founder Theo de Raadt, officially announced the release of a new version, OpenBSD 6.8.
Starting in October 1995, OpenBSD 6.8 is its 48th release that comes with numerous updates, a new arm64 and armv7 hardware support, security and kernel improvements, and new userland features.
As you may know, OpenBSD is a free, open source, and security-oriented 4.4BSD-based UNIX-like operating system. It is also one of the most popular distributions of the BSD family.
OpenBSD 6.8: What’s New?
As OpenBSD already supports a number of platforms such as alpha, amd64, arm64, armv7, hppa, i386, landisk, macppc, octeon, loongson, and sparc64, version 6.8 has now added support for a new powerpc64 platform including POWER8 and POWER9 CPUs.
OpenBSD 6.8 now features time-counting in userland to eliminate the need for context switching whenever a process needs the current time. Subsequently, it improves the speed and responsiveness of several real-world software like browsers and office suites.

Additionally, it has also brought new userland features along with bug fixes and tweaks. For instance, the ability to set and display video control values directly on the command line, control for backlight compensation to video utility, and a darker xenodm (X Display Manager) login widget.
Furthermore, v6.8 also includes various kernel improvements including a new
kstat utility that allows kernels to expose statistics to userland.
Here’s a brief summary of other key updates to OpenBSD 6.8:
- Improved hardware support and driver bugfixes
