0.10.7

What's Changed

Highlights ⭐

• 🧪 Test notebooks with pytest!. It's now possible to test notebooks using pytest! Running pytest test_notebook.py will run and test all cells whose name starts with test_*. This is only possible because marimo notebooks are stored as code (Python, not JSON!). Learn more at our docs. Shoutout to @dmadisetti for contributing this feature!

• 🔬Experimental tracing panel. This release includes an exciting new experimental tracing panel, giving you insight into which cells run, when, and for how long. Shoutout to @Light2Dark for contributing this feature! Enable it through the user settings (⚙ icon at the top right of your notebook).

• 🖱 Usability improvements. This release includes a number of usability improvements, including helpful prompts when you accidentally try using IPython magics, the ability to copy/paste the contents of a notebook file directly into the notebook (pasting creates cells!), the ability to use sandboxed notebooks with HTML export (thanks @metaboulie for contributing this!) and a few bug fixes.

⭐ Highlights

🚀 Major Features

• This release includes a new command, marimo export html-wasm, to export your notebook as a WebAssembly-powered HTML file. This lets you publish your marimo notebooks on GitHub Pages, without paying for any servers — the web browser executes your Python code instead! Learn more at our docs. WebAssembly notebooks do have some limitations on the packages that can be used
• It is now possible to automatically snapshot your notebook to .ipynb files while editing; this lets you save a snapshot of your notebook outputs that you can view on GitHub. Enable this feature through the notebook settings menu (top right, ⚙️ icon).
• Added support for Azure OpenAI with AI Assistant
