Hardware support has been expanded to include the latest processors and graphics cards, including AMD’s Ryzen AI 300 series (Strix Point, Strix Halo, Krackan Point), Radeon RX 9070 graphics cards, and Intel’s Arrow Lake processors. This release substantially improves multiple areas, including performance optimization, hardware support, and security enhancements. New network hardware drivers have also been added, including ice(4) for Intel E810 Ethernet devices and ixv(4) for virtual functions of Intel 82598EB, 82559, and X540 controllers. Security remains a cornerstone of OpenBSD, with this release implementing the separation of the user authentication code from the sshd-session binary into a dedicated sshd-auth binary. Installation and upgrade processes have been simplified with improvements to sysupgrade(8), which now supports specific release version targeting and offline upgrades from filesets stored on a filesystem. For developers, the system provides LibreSSL 4.1.0 with numerous internal improvements and optimizations, including new SHA-1, SHA-256, and SHA-512 assembly implementations for amd64 that leverage SHA-NI instructions when available. The new version features notable performance improvements, particularly on ARM64 architecture, where the PMAP teardown has been optimized by skipping TLB flushes, resulting in approximately 5% faster kernel builds. For AMD64 systems, OpenBSD 7.7 now supports running as an AMD Secure Encrypted Virtualization (SEV) guest on QEMU with EFI, strengthening virtualization security.

For USB device users, version 7.7 introduces USB 3.0 speed support to the xhci(4) and uvideo(4) drivers, addressing longstanding performance limitations. This algorithm is designed to resist potential attacks by quantum computers while maintaining backward compatibility with current security standards.
