Elasticsearch 5.0.2 has been released as a stable update, incorporating bug fixes and improvements from its previous versions based on Lucene 6.2.1, and is available for deployment on Elastic Cloud. The update addresses several critical issues, including a bug in X-Pack that previously hindered rolling upgrades from version 5.0.0 to 5.0.1, frequent failures under load due to caching issues in X-Pack Security, and cluster instability that could lead to unallocated primary shards. Enhancements include the introduction of a HostFailureListener in the Transport Client to manage node connectivity and the ability for the Tribe node to use custom ports. Users are encouraged to upgrade to this version, provide feedback on social media, and report any issues through GitHub.
