Kibana 6.3.0 introduces several enhancements and new features aimed at improving user experience and functionality, particularly with the opening of X-Pack. Notable updates include license management changes, allowing users access to all Basic features of Kibana X-Pack by default, and the introduction of auto-complete in the Query Bar to simplify syntax and improve ease of use. The release also adds a "Recently viewed" section and time picker to help users return to previous work, refines Dashboard panel sizing, and introduces chained input controls for more dynamic data filtering. Additionally, the version enhances index management through a new UI, integrates interactive map support in Vega, and streamlines monitoring activation under the Basic license. Developers benefit from console enhancements and an updated method to inject server information into the browser, improving API usability and overall system performance.
