What makes you think the DNS *protocol* changes just because one
implementation of that protocol has a new version? Just think of the
massive interoperability problems there would be all over the world if
that were the case every time a new name server version was released.

You might find that a BIND8 name server is less forgiving about zone
file errors - like illegal hostnames and bad glue records - that you
used to get away with in BIND4. This is not a change of protocol, just
a more rigorous interpretation of it.
