## Summary
Theo de Raadt released OpenBSD 8.0, the 61st version of the security-focused BSD operating system. The release significantly expands hardware support, particularly for x86_64, ARM64, and RISC-V platforms. Notable changes include Intel Arc A-Series graphics support through updated DRM drivers, a 128x expansion of AMD64 virtual address space, and ARM64 hibernate functionality.

## What's new in OpenBSD 8.0
- **AMD64 VAS expansion**: Virtual address space increased from 4G to 512G
- **Graphics**: DRM drivers updated to Linux 6.18 kernel state; initial Intel Arc A-Series Alchemist support added
- **ARM64**: Hibernate support added
- **RISC-V**: "V" vector extension and new CPU ISA capabilities supported
- **SPARC64**: Migrated to LLVM/Clang toolchain
- **Dropped**: Loongson architecture support retired due to LLVM Clang 22 incompatibility
- **Packages**: GCC 16.1, GNOME 49, KDE Plasma 6.7.5, LLVM Clang 22, Python 3.14.7, Rust 1.98.1, Wayland 1.26, Xfce 4.20

## Why it matters
The Intel Arc A-Series support and Linux 6.18-based DRM driver update narrow the graphics hardware gap between OpenBSD and Linux on x86_64 desktops. The 512G AMD64 address space expansion enables significantly larger memory workloads, while RISC-V vector extension support strengthens OpenBSD's position in the growing RISC-V server and embedded ecosystem.
