DataStax drivers team released the new major version of the driver at the begin of 2019th - version 4. The new version makes driver more modular, brings more functionality and stability. The existing driver (3.x) is put into maintenance mode, so it won't receive new functionality - only bug fixes. The new driver also deprecates very outdated versions of Cassandra (older than 2.1).
It would be nice to discuss the possibility of migrating Cassandra interpreter to a new driver.
