Marimo

What's Changed

New Features

**Autoreload modules.** marimo can now be configured to automatically reload modules before executing cells, bringing in any modifications you may have made to modules used by your notebook.

If you're coming from IPython/Jupyter, this is similar to the `autoreload 2` magic.

Enable it in your settings:

**Snippets.** marimo now ships with a library of code snippets that you may find useful when working with data. Open the snippets panel via the toolbar at the bottom of a marimo notebook. We'll add more snippets over time; if there's a snippet you'd like to contribute, just click the `+` button in the snippets panel to send it our way.

Other improvements

**`mo.audio`**: you can now pass a path to a file to `mo.audio`, and it'll do the right thing. This function now accepts arbitrarily large audio files.

**`PyArrow` tables**: `mo.ui.table()` now supports `PyArrow` tables.

**Lazy evaluation/rendering of components** The new library function [`mo.lazy()`](https://docs.marimo.io/api/layouts/lazy.html#marimo.lazy) lets you defer the computation and rendering of components, especially useful if you have expensive components that are hidden by default (e.g., in a tab or accordion).
