⭐ Highlights

• Configuration can now be overridden using pyproject.toml, providing more flexibility in managing notebook settings. This goes under the [tool.marimo] settings. To learn more about the configuration exposed, run marimo config describe
• Frontend performance improvements to prevent unnecessary re-rendering
• marimo.create_asgi_app supports ASGI middleware (e.g. for authentication/authorization)
• Export to .ipynb improvements/interoperability. For example: marimo export ipynb nb.py -o snapshot.ipynb --include-outputs --sort=top-down. You can use this to view the outputs in GitHub or pipe the results in your other tools.
