There may be a regression.  Testing with 2.1.7 and 2.1.8 I get the following:

{code}> cqlsh_to_2_1_server.sh
[cqlsh 5.0.1 | Cassandra 2.1.4 | CQL spec 3.2.0 | Native protocol v3]
Use HELP for help.{code}

When I upgrade to 2.2.0 client I immediately get the problem occurring again.

{code}> sudo apt-get install cassandra=2.2.0
Unpacking cassandra (2.2.0) over (2.1.8) ...

> cqlsh_to_2_1_server.sh
Connection error: ('Unable to connect to any servers', {'sqa-cassandra01': ConnectionException(u'Did not get expected SupportedMessage response; instead, got: <ErrorMessage code=0000 [Server error] message="io.netty.handler.codec.DecoderException: org.apache.cassandra.transport.ProtocolException: Invalid or unsupported protocol version: 4">',)}){code}

Edit: simplified example

> The response to a STARTUP request with protocol v4 on a C* 2.1 host is an error with an incorrect error code (0). 
> Instead of the error code being "Protocol error" ({{0x000A}}) it has error code 0 and message (wrapped by netty): 
> {{"io.netty.handler.codec.DecoderException: org.apache.cassandra.transport.ProtocolException: Invalid or unsupported protocol version: 4"}}
