OpenBSD 8.0 is available: changes and upgrade preparation
English edition published on .
OpenBSD 8.0 has been available since 20 October 2026. It brings changes for some ARM laptops, Intel graphics cards and virtualisation. Before installing, consider your starting point: exploring OpenBSD on a test machine or upgrading a system already in use.
The official project website confirms the release. OpenBSD belongs to the BSD family and is not a Linux distribution. Our OpenBSD profile introduces the system, its uses and software; the BSD systems category helps you compare projects.
Three changes to consider for your use case
The OpenBSD 8.0 release notes describe many changes. These three may help you decide what deserves closer attention:
- ARM64 laptops: hibernation support has been added. Reassess what your hardware supports without assuming that every model and peripheral is compatible.
- Intel graphics: the inteldrm driver now supports Arc A-Series cards, also called DG2/Alchemist. Identify your exact card before comparing the announced capabilities.
- Virtual machines: VMM/VMD gains support for multiple virtual CPUs, up to 64 per guest. This stated limit is not a performance measurement for your workload.
For an everyday computer, make a short list covering networking, display, audio and essential applications. One useful feature cannot validate the entire setup. The software questions in our guide can help you prepare; its Linux procedures do not transfer directly to OpenBSD.
Already using OpenBSD: preparing an upgrade from 7.9
The official 7.9 to 8.0 upgrade guide states that upgrades are supported only between consecutive releases. If you use an older version, do not skip documented steps.
Read the configuration changes and package instructions before starting. In particular, the guide requires the /usr partition to be at least 1.1 GB. Checking partition size does not replace checking available free space. For a critical or remote machine, the project recommends testing on an identical local system first.
sysupgrade is one supported method: it downloads installation sets, verifies their signatures and reboots to perform the upgrade. Plan for downtime and recovery access. Back up your documents and configuration before choosing a method; post-reboot steps are also part of the procedure.
First installation: choosing and verifying the right media
Start with the official installation and download guide. Choose your architecture before the format: install80.img is a USB image containing installation sets, while miniroot80.img obtains them separately. ISO images serve optical media or a compatible virtual drive. Not every format is available for every platform.
The documentation distinguishes SHA256 checks, which detect changes to a file, from cryptographic verification using signify and SHA256.sig. Follow the instructions for your chosen file and architecture, using the appropriate official key. Verify the image before preparing media and identify the destination device precisely.
Start learning in an environment you can reinstall. A virtual machine helps you learn installation and administration but does not reproduce all your computer’s hardware. To compare BSD approaches, see our FreeBSD profile; its tools and procedures remain distinct.
After installation: follow fixes and check your tasks
Consult the OpenBSD 8.0 errata for base-system fixes. The page explains signed patches and use of syspatch where supported by the architecture. If upgrading, also complete the configuration and package-update steps in the upgrade guide.
Keep your backup until you have checked your applications, data and expected services. This article describes documented changes and preparation; it does not report an installation test performed by distrib.wiki.
