Apache Superset 4.0 Release Notes

Apache Superset 4.0 marks a significant milestone with a comprehensive update aimed at enhancing stability, maintainability, and user experience. This release introduces major architectural changes, new features, and a redesigned Alerts and Reports modal, while also removing deprecated features and upgrading dependencies. These improvements are part of a broader effort to streamline the release process and ensure a more reliable system, with a focus on business logic improvements and enhanced drag-and-drop functionality. Superset 4.0 also includes a new tagging system for better organization, a revamped CHANGELOG format to manage release information efficiently, and the migration of the Sunburst chart to ECharts for better performance. The release process has been refined through community consensus, leading to a more efficient "release train" model, with future plans to stabilize releases and drop support for older versions. The community is encouraged to contribute to the project's ongoing development and adoption, ensuring continued growth and improvement.
