Screenshot of OpenBSD 8.0: released Oct 20, 2026

OpenBSD 8.0, released October 20, 2026 as the project's 61st release, continues the project's emphasis on correctness and security while adding broad platform and architecture-specific improvements. Notable kernel-level changes include raising the amd64 kernel virtual address space from 4 GB to 512 GB and randomizing the pmap direct map, using AES CPU instructions to speed swap encryption on amd64/arm64, and adding hibernate and bounce-buffer support on arm64. RISC-V gained userland-exposed CPU extension detection, kernel support for the V (vector) extension, new IMSIC/APLIC interrupt drivers and timer support; sparc64 moved to an LLVM toolchain and saw alignment fixes. Legacy loongson support was retired.

Work touched almost every subsystem: suspend/hibernate robustness and resume fixes; DRM updated to Linux 6.18.53 and Intel Arc (DG2/Alchemist) support; VMM/VMD extended to 64 VCPUs, x2apic, improved exit handling, virtio/MSI support and better qcow handling. Userland utilities saw targeted enhancements (netstat multicast counters, mount DUID handling, sndiod controls), while installer/pkg/fw_update received stricter validation and improved behavior. Extensive hardware and networking driver additions and bugfixes (new samsabi, sambat, rkotp drivers; many qwx/qwz wireless fixes and 802.11n support) were included. Security fixes hardened pledge, IPsec AES-GMAC, iked IKEv2 handling, libcrypto/x509 behaviors and DHCP/DHCPD resilience, among other memory-safety and overflow protections.
