OpenBSD 8.0 introduces major hardware and toolchain improvements, notably updating graphics drivers to Linux 6.18 for better Intel Arc support and transitioning entirely to the Clang/LLVM 22 compiler. The release significantly boosts virtualization by supporting up to 64 VCPUs per guest and adds new hardware drivers for Qualcomm WiFi and Samsung battery monitoring. Additionally, the update brings accelerated swap encryption and enhanced filtering capabilities to the built-in httpd web server.
