Highlights ✨

🪐 ➡️ 🍃 **A new and improved auto-converter from Jupyter to marimo.** This release substantially improves our tool for converting Jupyter notebooks to marimo notebooks — you no longer have to resolve multiple definition errors on your own, and some popular magic commands are replaced with marimo equivalents.

Try it at the command-line: `marimo convert nb.ipynb > nb.py`.

Converting from Jupyter to marimo gets you freebies like a much more powerful [dataframe viewer](https://docs.marimo.io/guides/dataframes.html) and [editor](https://docs.marimo.io/guides/editor_features/index.html) (including GitHub copilot, AI completion, and data source panels), with zero effort required on your part.

📦 **Making it easier to start [sandboxed notebooks](https://marimo.io/blog/sandboxed-notebooks).** If a notebook encapsulates its own dependencies, marimo now prompts you to open it an a temporary venv, with its packages automatically installed:

✅ **`-y` option for our CLI.**  Adds a CLI `-y` option that when enabled automatically confirms "yes" for interactive prompts.

🖱️**Multi-select improvements** Select and unselect all, with one click.
