Mercury 3.2.13 strengthens standalone app security and updates dependencies.
Security
- Improved session isolation and restricted shared-session widget updates.
- Limited access to server events and kernel configuration details.
- Updated Jupyter and frontend dependencies with security fixes.
Compatibility
- Requires Python 3.10 or newer. Building from source requires Node.js 22.12 or newer.
- Custom widgets can still render, but browser updates require an explicitly supported widget policy in standalone mode.
