Elasticsearch 2.3.0 and 2.2.2 have been released, featuring significant updates and new features designed to enhance user experience and prepare for future versions. Elasticsearch 2.3.0 introduces the highly requested reindex API, update-by-query API, and task management API, facilitating easier data reindexing, document updating, and task monitoring or cancellation, respectively. These additions are aimed at simplifying complex operations like reindexing terabytes of data and managing long-running tasks. The update also includes deprecation logging to help users identify outdated features that will be removed in Elasticsearch 5.0. Alongside these Elasticsearch releases, new versions of Kibana, Logstash, and Beats have been launched, all available on Elastic Cloud. Users are encouraged to explore these enhancements and provide feedback through various channels.
