Elastic Stack 7.0 introduces major enhancements across its components, marking a significant release with over 10,000 pull requests from 861 contributors. Kibana 7.0 features a new design with a minimal UI, a global navigation system, dark mode, and responsive dashboards for improved mobile usability. In Elasticsearch, the release includes a new cluster coordination layer for better scalability and reliability, alongside a real memory circuit breaker to enhance node stability. Search capabilities are boosted with faster top k queries using the Block-Max WAND algorithm, simpler intervals queries for proximity-based searches, and an upgraded function score 2.0 for advanced search relevancy control. Elastic Maps benefits from a new geotile grid aggregation for stable zooming, and time series use cases see improvements with nanosecond precision timing, thanks to a shift from JODA to the Java time API in JDK 8.
