As mentioned by @Matrix User in the comments, the new firmware doesn't support selecting of the I²C address with the jumper pads on the bottom of the board — instead the address is fixed in the firmware. There is an issue reported about this at and some workarounds, including alternate builds of the firmware with different hard-coded addresses.
