Par Clinton Gormley

Today, we are happy to announce the bug fix release of Elasticsearch 1.7.3, based on Lucene 4.10.4. This is the latest stable release. Users are advised to upgrade if they find themselves affected by any of the bugs which have been fixed.

You can download Elasticsearch 1.7.3 and read the full changes list here.

Previous blog posts about the 1.7 series:

This release contains a number of bug fixes including:

  • Synced flushes were reactivating inactive shards, thus reducing the size of the index buffer available to truly active shards. This could result in smaller segments than normal being written, which in turn causes more merging, and slower indexing on nodes with many inactive shards. (#13802, #13759)
  • Snapshot/Restore operations were being throttled excessively. (#13828)
  • Tribe nodes connected to slow clusters were holding onto old cluster states for too long, resulting in heavy memory usage. (#13948, #13566)
  • The analyzer, index_analyzer, and search_analyzer mapping settings were applied in indeterminate order, making a smooth transition to 2.0.0 difficult. (#14060)
  • The networking layer had a bug in its SSL handling, which has been fixed by upgrading to Netty 3.10.5. (#14105)

Please download Elasticsearch 1.7.3, try it out, and let us know what you think on Twitter (@elastic) or on our forum. You can report any problems on the GitHub issues page.
