- bootloader, kernel, userboot, and devmgr now support FLAG_EXTRA for container headers as well as item headers - bootloader generates new style headers for prepended bootdata items when it detects a new style container header - mkbootfs generates large container headers when generating bootdata images with crc32 enabled - bootloader version bumped to 0.6.0 to mark the point of compatibility needed for kernels once we throw the switch to use new headers exclusively Change-Id: Ifcb78d62f882ddd869da8d73ffe774a0f7937bc0
