- Intel signed section identified as EFI_FIRMWARE_CONTENTS_SIGNED GUIDed section - solved a bug with no element for "Non-UEFI data inside pad-file" message - HP postcode section renamed to Insyde postcode (found in non-HP images) - various small fixes - this is the latest release without FFSv3 support, which requires massive refactoring round and can possibly last long
