Elasticsearch released version 6.1.3 and 5.6.7, both of which are bugfix updates aimed at improving stability and performance, with version 6.1.3 being the latest stable release available for deployment on Elastic Cloud. These updates are based on Lucene 7.1.0 and 6.6.1, respectively, and address several critical issues, including a bug where transient cluster settings were not applied after setting additional persistent settings, and a problem with replica recovery entering an endless flushing loop. Several improvements were also made to snapshot/restore edge cases. Users are encouraged to download the new versions, test them, and provide feedback via Twitter or the Elastic forum, with any issues being reportable on GitHub.
