Superset 2.1 Release Notes

Apache Superset 2.1.0 introduces various new features, enhancements, and security improvements, addressing a significant security issue by requiring users to change the default SECRET_KEY to prevent production mode booting with default settings. The update includes new visualization capabilities, such as a generic non-temporal X-axis for ECharts and horizontal filter bars for dashboards, while also enabling users to drill down into chart details and export data in XLSX format. Performance improvements have been made, with more components moved to a React single page application and support for Python 3.11, which enhances speed. Database connectivity sees enhancements with added support for ClickHouse, Risingwave, and improved authentication options for Snowflake and Presto/Trino. Internationalization efforts have brought improved translations in several languages, and further strides have been made in API V1 migrations. The release also includes numerous bug fixes and general improvements aimed at enhancing user experience and security, with ongoing community efforts toward the development of Superset 3.0 anticipated to bring further advancements.
