2017-02-13

Notable Changes

  • Removed cassandra-driver external dependency. The DSE driver is now self-contained.
  • Support for DSE 5.1 EAP3.

Notable Changes

  • Promise support (#194).
  • Timestamp generation: client-side timestamps are generated and sent in the request by default when the server supports it (#195).
