What's Changed

This release makes it easier to share slide decks, browse files across directories and GitHub repositories, in addition to many other bug fixes. Some other changes include better geospatial data support with GeoPandas, polars and duckdb, web assembly optimizations, and a condensed graph view to understand your notebook's dependencies.

⭐️ Highlights

Export slides to HTML and WebAssembly

Share notebooks in the slides layout as reveal.js decks, preserving slide structure, fragments, and deck settings. Export static HTML with captured outputs, or use WebAssembly to keep Python controls interactive in the browser. 

marimo export html slides.py -o slides.html
marimo export html-wasm slides.py -o slides --mode run
reveal-slides

Read the docs for static HTML, or learn about interactive WebAssembly exports.

Browse local folders and GitHub repositories

Keep project files, data directories, and GitHub repositories within reach in the Files panel. Add named local directories in pyproject.toml, or use Add Connection to connect a GitHub repository and browse its files.

folders = [
    { path = "/absolute/path/to/data", name = "Data" },
    { path = "/absolute/path/to/assets", name = "Assets" },
]

Read the docs for additional local folders, or learn about remote storage connections.

A compact view of notebook dependencies

The dependency graph now shows compact variable summaries, making it easier to follow connections in larger notebooks. Double-click a cell in the graph to expand its code.
