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.
