What's Changed

Highlights

🏃 Fewer cell re-runs when importing modules. In version 0.8.0, marimo minimizes cell re-runs when importing modules: if you incrementally add imports to the same cell, only cells depending on the newly imported modules will run. This means that you can now collect all your imports in a single cell without having to worry about marimo running cells unrelated to the new imports.

👌 Quality-of-life improvements. Toggle presentation view from the notebook menu; use Meta+z to undo cell deletion; faster table loads for large tables; create files and folders from the file explorer; undo splitting cells; and more!
