[JDEV] Protocol Changes

[Stephen Pendleton]

It seems that there has been a slight protocol change on the jabber.org
development server. In particular, when registering on a gateway it used to
be required that a "key" was exchanged between the client and the server.
Now it seems that the requirement has been dropped and clients that send the
key in the XML stream get disconnected. Unfortunately this requires that all
the clients that used the key-exchange method need to be updated and
redeployed.

It seems to me that any changes to the server protocol need to be done in a
way to ensure backward compatibility with the previous versions of the
protocol. Is this just a bug in the server, or was this intentional?

Thanks!
