SymmetricDS 3.10.2 is released. Together with 3.10.1, these releases include 13 bug fixes and 10 improvements. (NOTE: If you are using 3.10.1, the router service has a broken query in this version, so we strongly advise upgrading to 3.10.2 to ensure routing runs efficiently.) Here are some improvements to highlight:

  • Initial Apache HBase support
  • MongoDB clusters support
  • Re-clearing target table if initial load extract is interrupted

See the 3.10.2 change log and 3.10.1 change log for more details.
