On July 29, Elastic published two releases for Elasticsearch, Versions 1.6.2 and 1.7.1.
Version 1.6.2 contains a number of bug fixes, including a fix for a rarely occurring but important bug that can cause data loss. For the rare case in which a cluster experiences multiple simultaneous node failures or restarts, the bug in question can cause deletion of all copies of a shard from the cluster. This bug is traceable to release 1.5.0.
1.6.2 also contains a fix that covers CIDR mask conversion for IPv4 addresses, as well as a bug that prevents Shield users from using the more-like-this API. There are also a a few more changes that you can learn about in the changes list.

Qbox customers should contact support as soon as practicable to request an upgrade of their clusters to the releases. Remember: the Qbox team advises all users to upgrade.
