What's Changed

This release gives mo.ui.table finer display control (fixed column widths, a toggleable search bar, and a reusable display config).
Additionally mo.output.clear_console() adds a way to clear console output mid-run, and ships a broad set of fixes across AI config, exports, and the data sources tree.

Various other bug fixes like matplotlib==3.11 support in mo.mpl.interactive and pydantic-slim integration also ship in this release.

⭐️ Highlights

More control over mo.ui.table display

You can now size and trim tables to fit your data. column_widths pins named columns to an exact pixel width (great for long file paths or notes that used to get clipped), while unlisted columns continue to size to their content. The search bar is now toggleable via show_search, and the four visibility flags are available as a reusable mo.ui.table.Display config you can build once and unpack into many tables (#​9982, #​9984).

mo.ui.table(df, column_widths={"filename": 600, "id": 60})

# Reusable display config
cfg = mo.ui.table.Display(show_search=False, show_download=False)
mo.ui.table(data, **cfg)
mo.ui.table(other, **{**cfg, "show_column_summaries": False})

Clear console output mid-run

mo.output.clear_console() clears a cell's console output while it's still running, and the clear now sticks across reconnects, exports, and the on-disk session cache, not just in the live view. This replaces the old "re-run the cell to clear it" workaround.

✨ Enhancements

• Add show/hide all code commands to command palette (#​9989)
• Add show_search and a reusable mo.ui.table.Display config (#​9984)
• Add column_widths to mo.ui.table (#​9982)

• Add more trace attributes under an AI span (#​9968)
• Only auto-expand search matches in the data sources tree (#​9955)
• Disable settings overridden by pyproject.toml (#​9961)
• Tighten markdown heading spacing (#​9962)
• Add mo.output.clear_console() (#​9950)

What's Changed

This release brings threading and multiprocessing to WASM notebooks and makes remote storage browsing scale with search and pagination — alongside table column controls, slide editing improvements, and a broad set of fixes.

⭐️ Highlights

Pyodide 314.0

This release moves marimo's WebAssembly runtime to Pyodide's latest release: Pyodide 314.0. This allows use to use newer versions of duckdb, polars, and pyarrow as well as many other popular packages.

Threading and multiprocessing in WASM

WASM notebooks can now run threading- and multiprocessing-shaped code. marimo installs lightweight adapters for Pyodide so mo.Thread, stdlib threading primitives, and common multiprocessing APIs keep working in the browser, executing on a synthetic thread identity that the marimo runtime context follows (#​9839).

Scalable remote storage browsing

Browsing large remote storage backends is now practical. Listings paginate behind a "Load more" button instead of loading everything up front, and when a prefix query matches none of the already-loaded entries, marimo pages through the backend to surface remote results — matching on full paths so partial path queries resolve, with clear status while it searches (#​9834, #​9835).

✨ Enhancements

• Search the backend when no loaded entries match (#​9835)
• Honor OTEL_SERVICE_NAME for traces (#​9906)
• Progressively mount cell editors in the editor view (#​9904)
• Generate Google Drive connection code for embedded environments (#​9884)
• Paginate remote storage listings with a "Load more" button (#​9834)
• Threading and multiprocessing adapters in WASM (#​9839)

• Column visibility dropdown in table top bar (#​9865)
• Support ROCM for /api/usage endpoint (#​9773)
• Shared select-core for multiselect, dropdown, and filter picker (#​9849)
• Per-slide show-code config + editor toggles (#​9831)
• Resolve definitions and get docstring (#​9838)
• Minimap insert-cell + context menu (#​9830)
• Add a toggle to filter empty schemas and db (#​9712)

• Land focus in target cell on right-click Go to Definition (#​9795)
• Fix reactive go-to-definition lookup (#​9747)

What's Changed

This release makes opening a notebook in a second tab non-destructive, mo.ui.table adds new args for hidden_columns/visible_columns (mutually exclusive), and tightens sharing and error-output behavior across the board.

⭐️ Highlights

Open the same notebook in a second tab

Opening a notebook in a second browser tab no longer forcibly disconnects the first. The new tab joins as a live, read-only viewer, and you can take over editing from either side with a single click — no destructive modal and no reload required (#​9746).

Show and hide table columns

mo.ui.table now supports column visibility. Hide and show columns from the column header menu, Column Explorer with a click, find columns fast with smart prefix-based search, and control initial visibility from Python. A hidden-count and "Unhide all" link keep things discoverable (#​9687, #​9696).

Cells with no output now show in slides

Because slides allow code edits, a slide edited to no longer produce an output used to disappear from the deck entirely. Such cells now appear in the slides minimap and viewer so you can edit them back in (they're still skipped during a presentation). Minimap thumbnails are also larger and more readable (#​9771).

✨ Enhancements

• Add MARIMO_RESTRICT_SHARING env var machine-wide (#​9756)
• Non-destructive local takeover (read-only viewer + bidirectional takeover) (#​9746)

• Add workflow to automate running llm-sync-models script (#​9724)
• Automation script to pull models.yml (#​9635)
• Support Dremio ADBC data source browsing (#​9694)
• Add auto_close_pairs setting (#​9711)
• WASM compatibility rule checks (#​9587)

What's Changed

This release includes quality of life improvements to marimo slides, bug fixes to marimo islands that revive our quarto extension, a new lint rule, and minor security improvements.

⭐ Highlights

Slides minimap

Slide mode now has a minimap: a scrollable panel showing your cells at reduced scale, with click-to-navigate and drag-to-reorder support. It's performance-aware — cells only render in the minimap when they're in view.

Islands revived

We've fixed many bugs with [marimo islands], a way to embed marimo outputs and/or Python code in other HTML. These fixes also make our quarto-marimo. (#​9071) extension compatible with this version of marimo as well.

Security

This release includes minor security improvements, including input sanitization, path traversal prevention, open redirect blocking, and auth endpoint hardening.

• Sanitize plugin output slots (marimo-mpl-interactive, marimo-panel) to prevent script injection (#​9133)
• Restrict head_html injection to run mode only (#​9137)
• Prevent directory traversal via symlinks in asset serving (#​9134)
• Sanitize user-supplied custom.css (#​9131)
• Block open redirects via protocol-relative URLs (e.g. //evil.com) (#​9112)
• Restrict health endpoint exposure and add path validation for document writes (#​9115)

We've also updated our security documentation with a standard operating procedure for future disclosures (#​9114).

Thank You. The enthusiasm following our recent CVE disclosure is a testament to what a healthy open-source community looks like. A special thank you to @​GCXWLP, @​Jvr2022, @​offset, @​l3tchupkt, @​Fushuling, @​RacerZ-fighting, and @​q1uf3ng for their engagement and reports during this sprint. It takes a community to keep FOSS secure. We're lucky to have this one!

Security Announcement

This release contains important security updates for CVE-2026-39987. See Terminal WebSocket Authentication Bypass

The /terminal/ws endpoint is accessible without authentication on default marimo installations. This allows for unauthenticated users to remote execute code via this endpoint.

Who is affected

• If you have deployed marimo as an editable notebook (not an application) to the public internet and only using marimo’s built-in authentication.
• If you expose marimo to your shared network using --host 0.0.0.0 and while in edit mode (not an application).

Likely not affected

You are not affected if any of these are true.

• If you have your own authentication proxy on top of editable marimo notebooks.
• If you are not exposing marimo to the public internet
• If you are running marimo as an application (in run mode)
• WebAssembly (WASM) notebooks are not affected
• molab is not affected

Please upgrade to 0.23.0 or later.

What's Changed

This release launches marimo pair — an agent skill that drops AI agents directly inside a running marimo notebook session — along with a cleaner, more responsive data table experience and a slate of reliability fixes.

⭐ Highlights

marimo pair: collaborate with agents inside your notebook

marimo pair is a new agent skill that gives AI agents full control over a running marimo notebook session — accessing live variables, executing cells, installing packages, and building reproducible programs alongside you. This release adds the marimo pair prompt CLI command, a "Pair with an agent" modal in the notebook menu, and a secure --with-token auth flow that keeps credentials out of shell history.

Smarter table headers and responsive column layout

Column headers are now split into a dedicated sort button (cycles asc → desc → clear on click, hidden until hover) and a separate ⋯ menu button for column options. Tables with ≤ 4 columns automatically use natural width with a filler column; larger tables fill the container. Vertical column separators complete the refresh.
