Apache Superset Repo Recap: July 2026

Apache Superset’s July update reported its busiest month of the year, with 132 contributors merging 664 pull requests, 47 new repository contributors, nearly 500 additional GitHub stars, and expanded community participation. Major foundational changes included a unified Subject access-control model that separates user, role, and group resource assignments from capability permissions, plus opt-in soft deletion and restoration for charts, dashboards, and datasets. Export capabilities expanded with asynchronous multi-sheet Excel dashboard exports, XLSX reporting, and PNG and PDF chart downloads, while new backend theme settings allow administrators to customize interface elements and default light or dark modes without modifying source code. Other additions included partial pie and donut charts, dashboard filter-cache improvements, Databricks OAuth support, Apache DataFusion connectivity, enhanced SQL Lab behavior, and extensive MCP tools enabling AI clients to query semantic layers, manage themes and content, use guest authentication, and work with deleted resources. The release also addressed security issues, expanded row-level security visibility, introduced broader internationalization efforts with reviewed and safeguarded machine-assisted translations, upgraded Ant Design, added extension storage and dormant entity-versioning infrastructure, and incorporated 197 dependency-update pull requests.
