Updates marimo from 0.20.4 to 0.21.0

Release notes

Sourced from marimo's releases.

0.21.0

Builtin interactive matplotlib

mo.mpl.interactive() has been rewritten to use marimo's built-in communication channel instead of a separate server and WebSocket proxy. This means interactive matplotlib plots now work with no background threads or separate server process needed.

Download notebooks as ipynb

You can now export your marimo notebook as a Jupyter .ipynb file directly from the editor's download menu. Cells are exported in visual order with their captured outputs included.

🚨 Breaking changes

  • Altair charts no longer stretch to full container width by default (#8696). Previously, marimo set width: "container" on all Altair charts, which distorted aspect ratios, made charts look different from the Altair docs. Charts now render at Altair's native default size. If you want a chart to fill the container width, set width="container" explicitly in your chart spec.

✨ Enhancements

  • Accept list args in ctx.install_packages (#8703)
  • Add different auth options for Snowflake in the UI (#8661)
  • Add read file and download snippets for storage inspector (#8640)
  • Ruff config discovery for notebook cell formatting (#8609)
  • Move matplotlib interactive to use marimo comm instead of over WS (#8612)
  • Refine type inference for cache decorators (#8629)
  • Improve command palette search with additional keywords (#8600)
  • Download notebooks as ipynb through UI (#8582)
  • Standardize file explorer icons, colors, spinner (#8571)
  • Add banner about GitHub free tier models (#8575)
  • Wait for buffered stdout/stderr before reading MCP execution results (#8577)
  • Format CellSelectionStats (proper aggregation, 3 decimal places) (#8564)
  • Storage inspector fixes and code gen update (#8566)
  • Add the ability to control the cache (#8311)
  • Add reactive histogram selection support (#8489)

🐛 Bug fixes

  • marimo export ipynb to support command-line arguments (#8709)
  • Tag install location on ModuleNotFound to distinguish installation on server vs kernel (#8619)
  • Fix copy to clipboard on Safari (#8587)
  • Debounce clearing of console outputs to prevent flickering (#8621)
  • Use explicit multiprocessing getcontext("spawn") (#8705)
  • Fix loguru messages not being printed (#8697)
  • Convert decimals to float64 for filtering in tables (#8706)
  • Catch generic exception when export to PDF (#8704)
  • Use request path to scope code-mode runtime behavior (#8702)
  • Add global previewed tables state (#8630)
  • Re-render mutable Html children in vstack/hstack on flush (#8626)
  • Fix Plotly selections returning points outside the selected range (#8685)
  • Ignore sql_refs for top level determination (#8673)
  • Send absolute path to frontend for file_browser (#8668)
  • Handle rust panic errors when getting config for obstore (#8658)
  • Don't search winpython in scanner for workspace files (#8633)
