I2C register layout changed a bit to make various operations easier to implement in FW and for the user. Flashing/debugging tools now share more code. Firmware is now more configurable (it's now possible to compile-out various features). Self-testing for column-shorts is implemented. Firmware is optimized for low power consumption.
