Key points
- Libreboot 26.10 released with UEFI support.

UEFI Support and Windows Compatibility
Libreboot 26.10 "Ominous Olive" now includes full UEFI support, implemented through the MrChromebox EDK2 payload. This addition makes Libreboot compatible with Microsoft Windows, broadening its usability beyond Linux and BSD operating systems. The change represents a significant design shift in the firmware.
Expanded Chromebook Hardware Support
The new release incorporates support for 233 Chromebook boards, sourced from the MrChromebox coreboot distribution. This expansion includes recent Intel and AMD hardware found in Chromebooks, with Baytrail (Kip) boards specifically tested. For this initial release, Chromebook support is source-only, requiring users to build from source rather than using pre-compiled binaries.
Major Design Changes and Anti-AI Policy
Libreboot 26.10 features several major design changes, with EDK2 now serving as the default payload. GRUB and SeaBIOS are provided as EFI builds for backward compatibility. Users are advised to review the changelog carefully due to these changes, which may affect existing setups. Additionally, a new anti-AI policy has been added to the AGENTS.md file within the lbmk project.
