What's Changed
Highlights ⭐
- 🧪 **Test notebooks with pytest!**. It's now possible to test notebooks using `pytest`! Running `pytest test_notebook.py` will run and test all cells whose name starts with `test_*`. This is only possible because marimo notebooks are stored as code (Python, not JSON!). Learn more at [our docs](https://docs.marimo.io/guides/testing/pytest/). Shoutout to dmadisetti for contributing this feature!
- 🔬**Experimental tracing panel.** This release includes an exciting new experimental tracing panel, giving you insight into which cells run, when, and for how long. Shoutout to Light2Dark for contributing this feature! Enable it through the user settings (⚙ icon at the top right of your notebook).
- 🖱 **Usability improvements.** This release includes a number of usability improvements, including helpful prompts when you accidentally try using IPython magics, the ability to copy/paste the contents of a notebook file directly into the notebook (pasting creates cells!), the ability to use sandboxed notebooks with HTML export (thanks metaboulie for contributing this!) and a few bug fixes.
