November 2023 Release

• Slightly more aggressive (but still within Bosch specs) sensor warmup profile
• Minor heater state machine improvements
• Allow standalone operation by starting sensor heating if the ECU doesn't take control within 5 seconds of power-on
• Add support for updating firmware on one controller at a time on a multi-controller bus (no bootloader update required to get this feature, just the main firmware)
