If you define a new protocol version as one that means devices with
older protocol generations of firmware/software may not interoperate
reliably with devices with new protocol generations of
firmware/software, then IPv4 as we know it today is probably at least
"IPv7" - address classes was a generational change requiring
software/firmware updates (compare addressing in rfc760 verses rfc791),
as was classful+subnets and then CIDR.
