The modern versions of the official operating system supports both V1.1 = and V1.2 of the board, allowing existing programs to continue to work on = newer boards. (At least that is my understanding.) It is a different SOC but with the new one configured for use for = extreme compatibility with the old one from what I can tell. (User space = code, anyway, including using official interfaces to things on the = board.) They do not claim to support 64 bit at all: just Cortex-A7 = compatibility. For their primary target customers it is not "completely different". That other operating systems might choose to go in a different direction = is not a consideration for them: what they support is very compatible = even though the hardware does not require such configuration. (I'd have preferred RPI2C vs. RPI2B for naming at least. But I'm not = using the official materials generally so the issue is more noticable.) =3D=3D=3D Mark Millard markmi at dsl-only.net
