This is not a question of new client with old server.  The new version of the 
client has a more secure default that will possibly prevent it from connecting 
to *any* server that is not adequately configured.

But it's a default, so the user can change it.

Consider the analogy that a new web browser comes out that verifies server 
certificates (as of course all respectable browsers do nowadays) whereas the 
previous version one didn't.  The right fix there is certainly not to 
downgrade this to a warning when connecting to an older web server.

Not to mention the security implications: A rogue server could simply pretend 
to be of an older version to circumvent the client's security check.
