tl;dr: Libreboot 26.10 adds full UEFI support via MrChromebox's EDK2 payload, replacing U-Boot on x86 and enabling Windows, modern Linux UKIs, and BSDs to boot on supported hardware. The release imports 233 Chromebooks from the MrChromebox project (source-only), switches AMD Fam15h boards like the KGPE-D16 to a 15h.org coreboot fork with proper AGESA init, and adds boards including the ThinkPad X270/X280 and several Dell OptiPlex models. The project also adopted a strict anti-AI policy, citing a vibe-coded U-Boot x86 fork as a key reason for migrating to EDK2.
