Full details of the changes in this release are available in the release notes listed above, but some of the more important changes are mentioned below:

Elasticsearch

  • The transaction log can be corrupted following a disk full exception and several attempts to recover the shard. This has been reported once in the wild.
  • Higlighting a query with the plain highlighter in the presence of a geo_point query now works correctly.

Marvel

  • Stale monitoring data can now be viewed.
  • Relocating shards are no longer counted as unassigned.

Shield

  • The index search wrapper is now a singleton to avoid a memory leak when repeatedly creating and deleting indices.

Watcher

  • The state of watches is now indexed correctly.

Conclusion

Please download Elasticsearch 2.3.4, try it out, and let us know what you think on Twitter (@elastic) or in our forum. You can report any problems on the GitHub issues page.
