             Summary: Remove pre-3.0 compatibility code for 4.0
                 Key: CASSANDRA-12716
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-12716
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Sylvain Lebresne
            Assignee: Sylvain Lebresne
             Fix For: 4.0


CASSANDRA-8099 make subsequent changes to internal formats so that we have quite a bit of backward compatibility code a bit over the place. Due to that, but also as a natural evolution, I believe we always had a tacit agreement that 3.0/3.X would be a mandatory step on the upgrade to 4.X, so that we can remove pre-3.0 compatibility (that is, we won't support going from any 2.x release directly to 4.0, you'll have to upgrade to at least some 3.0 release first).

I think it's time to create the 4.0 branch and remove that pre-3.0 backward compatibility code, which should clean code quite a bit, and that's the goal of this issue.
