OpenBSD 8.0 Adds Hardware Support While Keeping Security Focus

What changed

OpenBSD 8.0 arrived on October 20 as the project’s 61st release, continuing its twice-yearly schedule. It adds Intel Arc A-Series graphics support, ARM64 hibernation, expanded AMD64 address space, RPKI routing support, and support for up to 64 virtual CPUs per guest.

The release also includes improvements to LibreSSL 4.4.0, OpenSSH 10.6, and the virtualization stack. Loongson support has been retired because its port no longer works with Clang 22.

Why it matters

This is a practical compatibility release wrapped in OpenBSD’s unusually strict security culture. The larger AMD64 virtual address space grows from 4GB to 512GB, allowing the system to map more than 4GB of graphics memory. That makes Intel Arc hardware a more realistic option instead of an expensive paperweight.

The virtualization changes matter for operators running larger guests: OpenBSD can now support up to 64 virtual CPUs per guest. ARM64 hibernation also fills in a basic power-management feature on those systems, while the new RPKI-to-router daemon adds routing infrastructure for validating internet route information.

The project says its default installation has suffered only two remote holes in more than thirty years. That claim has not been independently verified in the reporting, but it explains OpenBSD’s appeal: the headline feature is still restraint. OpenBSD 8.0 modernizes hardware and virtualization support without abandoning the security-first identity that has shaped the project since its fork from NetBSD more than 30 years ago.
