September 2026 Summaries

Apache Superset’s August development cycle saw 108 contributors merge 727 pull requests, with major releases centered on asset recoverability and usability. Version history and soft delete became generally available and enabled by default, allowing users to preview, restore, archive, and eventually purge charts, dashboards, and datasets. Other headline additions included an opt-in mobile dashboard mode, a native Butterfly chart for paired metric comparisons, and Snowflake OAuth 2.0 support for per-user query impersonation and auditing. The release also expanded chart controls, dashboard filtering, embedding APIs, reporting reliability, MCP token scoping and observability, internationalization, and database and SQL Lab capabilities, while removing legacy visualization endpoints, advancing the SQLAlchemy 2.0 migration, and strengthening embedded-access security. Dashboard v2, Global Async Queries migration, and broader testcontainers-based database testing continued as in-progress efforts. The community added more than 480 GitHub stars, 72 new repository contributors, and 87 Slack members, while 267 dependency-update pull requests were merged to support security and stability.
