Ok.  I've only read 0.10 and 0.8, so anything that happened between
those two revisions is a mystery to me :-).  For some reason, I was
thinking that I needed the functionality of the header exchange, but
now I'm fairly certain that the topic is exactly what I need, and I
can't remember why I thought the header was the thing to use.

Ok, so the current server is 0.8 only, and the java and .net clients
can connect to 0.8 and 0.9 servers.  The rest of the page is just 0.8
compatibility, for both the server and the clients.  Is there a 0.9
compatibility page anywhere, for the clients and the server when the
0.9 implementation is started?
