Libreboot 26.11 "Rubber Duck," released on November 12, 2026, has transitioned most supported boards to EDK2-UEFI-only firmware, enabling Windows boot support while dropping several legacy payloads. The release warns users to migrate their OS installs to UEFI before flashing, as improper installation could prevent booting. Although legacy booting is still possible, it now requires additional steps through Libreboot's build system, and the new ReBIOS replaces previous methods for emulating VGA BIOS. While TPM 2.0 is enabled for compatibility, project founder Leah Rowe criticizes discrete TPM chips as "security theatre," emphasizing that the firmware's security is paramount
