2023-09-13: Initial release

• Initial manufacturing software
• Network Install is not available in this version
• rpi-eeprom-update uses self-update on Pi5 rather than recovery.bin. so that the update mechanism is the same on all boot-modes and the boot file-system is never modified by the firmware/recovery.bin. recovery.bin is still used by RPi Imager - bootloader update SD card images.
• Pi4 and Pi4 bootloader images and recovery.bin are not compatible. The 2711/2712 boot ROM ignores incompatible recovery.bin files.
