Elasticsearch 1.7.1 and 1.6.2 released

By Clinton Gormley

Today, we are pleased to announce bug fix releases of Elasticsearch 1.7.1 based on Lucene 4.10.4, and Elasticsearch 1.6.2. These releases contain a fix for a rarely occurring but important bug which can cause data loss. All users are advised to upgrade.

You can download them and read the full changes list here:

The bug in question (#12487) can, in very rare circumstances involving multiple simultaneous node failures or restarts, cause all copies of a shard to be deleted from the cluster. This bug was introduced in 1.5.0.

This release also contains a fix for CIDR mask conversion for IPv4 addresses, and a bug that prevented Shield users from using the more-like-this API, plus a few more changes whose details can be found in the changes list.

Please download Elasticsearch 1.7.1, 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.
