marimo 0.10.0

on Python PyPI

⭐ 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

🎨 UI/UX Improvements

• Enhanced markdown support with task lists, tabs, critic markup, emoji, and magic links
• Network URL now shown when running with host=0.0.0.0

⚡ Bug Fixes

• Fixed case sensitivity issues dataframe searches
• Fixed datetime in Altair charts
• Respect Python version from inline-scripts (PEP 723) when running with --sandbox

🛑 Breaking change: Nameless cells in the marimo Python file are now generated as _ (instead of __) to fix mypy and pyright lint errors
