Libreboot 26.10, codenamed "Ominous Olive", has been released by Leah Rowe, dated 15 October 2026. Libreboot is free, open source boot firmware that replaces proprietary BIOS and UEFI firmware on supported Intel, AMD and ARM64 hardware. It initialises core hardware such as the CPU and memory controller so that operating systems like Linux or BSD can boot. With this release, Microsoft Windows is also compatible, because Libreboot has added full UEFI support via the Mr Chromebox EDK2 payload.
The project's goal is to remove proprietary software from computers and to offer firmware that non-technical users can understand, while providing greater security and customisation than proprietary firmware. This release is described as very special, with several major design changes that may affect existing setups. The most important change is a strongly anti-AI policy added to a new file, AGENTS.md, in the lbmk repository.
The release also imports all 233 currently supported Intel and AMD Chromebooks from the Mr Chromebox coreboot distribution, including the most recent hardware. Baytrail (Kip) has been tested, while the others still need testing. These boards are source-only, so users must build them from source, as no binaries are provided.
Libreboot's version of Mr Chromebox coreboot uses the EDK2 UEFI payload as its default, with a Libreboot purple background and rainbow logo. Intel Management Engine is disabled by default at build time, and flash descriptor regions are unlocked. For backward compatibility, CSMWrap, GRUB EFI and Mem Test86+ are included within EDK2.
