Until now the native hardware was pulling PB5-7 down and checking if they were asserted high. BMPMV2b is pulling the pins down instead of high. The hardware version routine now determines the hardware version based on the fact if a pin is asserted at all. This means that if a pin is left floating, the version number bit will be 0, and if the pin is asserted either high or low the bit will be set to 1. While we were already at it the "monitor version" command in GDB will now also print the hardware version number.
