Latest stable release in 2.x:
Users should upgrade if they are affected by any of the issues listed in the release notes above. The more important changes are:
- The transport client now has a HostFailureListener to notify client code when a node is disconnected. Also, a bug was fixed which prevented the transport client from removing an old node.
- Cross-field multi-match queries did not work with synonyms.
- Function score query was not working with highlighting.
