Kibana 8.16 introduces a significant update to the Dev Tools Console, enhancing the user experience with a modern and intuitive design. The upgrade involves a two-phase transformation, starting with the migration from the Ace editor to the more advanced Monaco editor, known for its use in Visual Studio Code, to ensure consistency across Kibana's interface. The second phase focuses on user interface improvements, including support for copying requests in multiple languages like JavaScript and Python, a redesigned toolbar with new functionalities, and enhanced input and output panels for streamlined workflows. These updates aim to boost productivity by simplifying configurations, improving history tracking, and enhancing responsiveness for smaller screens. The advancements not only modernize the Console but also facilitate more efficient crafting and debugging of complex queries and exploration of Elasticsearch APIs. Users are encouraged to upgrade to Kibana 8.16+ to experience these improvements and provide feedback for future enhancements.
