    non-empty Cassandra table (SPARKC-338)
  • Support for Joda time for Cassandra date type (SPARKC-342)
  • Don't double resolve the paths for port locks in embedded C*.
    (contribution by crakjie)

  • Added support for IF NOT EXISTS (SPARKC-362)

  • Merged Java API into main module (SPARKC-335)

  • Fix NoSuchElementException when fetching database schema from Cassandra
    (SPARKC-341)
