Apache Superset Community Update: October 2025

Welcome to our comprehensive October 2025 community update! This month has been absolutely incredible for Apache Superset, with our amazing community contributing 221 pull requests that span everything from major new features to critical bug fixes and extensive UI improvements. This represents one of our most productive months yet, showcasing the vibrant ecosystem of contributors who continue to make Superset better every day.

October's contributions touched every corner of the platform - from groundbreaking AI integration capabilities to essential security fixes, performance optimizations, and countless user experience improvements. Let's dive into the highlights of what our community has accomplished!

Highlights

Revolutionary Chart Customization for Dashboards

The month's most significant feature comes from LevisNgigi with the introduction of dashboard-level chart customization (#33831). This game-changing feature allows dashboard viewers to dynamically modify how charts group data directly from the dashboard interface - no more editing individual charts! Users can now switch between grouping by country, region, or any other dimension with a simple dropdown, enabling true drill-down and slice-and-dice capabilities.

AI-Powered Superset with MCP Integration

aminghadersohi delivered a groundbreaking AI integration with the Model Context Protocol (MCP) service (#35163, #35835, #35877). This comprehensive implementation enables AI assistants like Claude to programmatically interact with Superset through 21 tools, 2 interactive prompts, and 2 resources. The system includes chart generation, dashboard creation, SQL execution, and data exploration capabilities - essentially bringing AI-powered analytics to Superset!

Massive Frontend Performance Boost

rusackas revolutionized our frontend development experience by replacing ESLint with OXC (Oxidation Compiler) (#35506), delivering an incredible 53x performance improvement - from 32 seconds to just 0.6 seconds for linting! This hybrid architecture maintains all existing code quality standards while dramatically speeding up development workflows.

Enhanced Table Chart Capabilities

The table chart experience received significant improvements this month.
