0.3.0

What's Changed

The default host is now 127.0.0.1; previously, marimo listened on all interfaces by default. This is the only change that might be considered breaking in this release.

Highlights.

• This change adds a new layout command, mo.carousel, which lets you create a simple slide-like presentation of of a list of outputs; you can even view a carousel in full screen!
• Some of you thought the default app width was too narrow, while others found full width too wide — we've added a third medium width!
• Experimental AI completion, powered by OpenAI: https://docs.marimo.io/guides/ai_completion.html
• Support for wrapping AnyWidget widgets and making them reactive — this also lets you write custom reactive plugins! https://docs.marimo.io/api/inputs/anywidget.html
