Marimo

What's Changed

Highlights

🎥 **Conditionally show a cell's code in its output.** Use [`mo.show_code()`](https://docs.marimo.io/api/outputs.html#display-cell-code-in-marimo-s-app-views) to include the cell's code in the output area, so that the code is visible even in the app view, when running with `marimo run`, and in HTML exports.

🌺**Improved Ibis support.** Performance improvements for our integration with Ibis, including native Ibis support in `mo.ui.table` and `mo.ui.dataframe`.

⌨ **Improved settings menu.** marimo is packed with configurable features, so many that we outgrew our simple user configuration menu. We've replaced it with a more easily navigable modal, making it easier for you to discover and configure our many settings.

Highlights

**📸 Automatically snapshot notebooks as HTML** This release includes a notebook-level configuration that, when enabled, periodically and automatically snapshots your notebook as HTML, saving the snapshot to a folder `.marimo` in the notebook directory.

This allows you to enjoy the best of both worlds — your notebooks are stored as pure Python, while your outputs are automatically stashed to a directory for later viewing.

**📦 Packge sandbox improvements.** We've simplified marimo's package sandbox: now, when you open a marimo notebook with

bash
marimo edit --sandbox notebook.py


marimo will automatically track the packages used by your notebook and save them in the notebook as inline script metadata, along with their versions.

**🐍 IPython/Jupyter compatibility.** We've increased our compatibility with Jupyter/IPython rendering, adding support for `_repr*_` methods as well as mimebundles.

This release adds `--sandbox` as a flag to `marimo new`, meaning you can create empty notebooks with sandboxed venvs from the CLI

shell
marimo new --sandbox


This can be helpful when using marimo as a scratchpad.
