title: Which CQL version corresponds to which Cassandra version?
body: <p>The CQL documentation is organized according to the CQL version, not the Cassandra product version. Obviously, I want to read the CQL documentation corresponding to the Cassandra release I'm using, but I can't find comprehensive info on which CQL version corresponds to which Cassandra version:</p>
  
  <ul>
  <li><a href="https://docs.datastax.com/en/cql/3.1/cql/cql_reference/cqlReferenceTOC.html" rel="nofollow">CQL 3.1 documentation</a> is titled "CQL for Cassandra 2.0 &amp; 2.1", but newer CQL docs no longer mention Cassandra versions</li>
  <li>The <a href="http://docs.datastax.com/en/landing_page/doc/landing_page/compatibility.html" rel="nofollow">Product compatibility</a> page only maps versions of OpsCenter, Cassandra and DataStax Enterprise</li>
  </ul>
  
  <p>Is there a simple page listing the version mapping?</p>
