([Full Changelog](https://github.com/jupyterlab/jupyterlab/compare/v3.0.6...60f37be54a714c391fad5500cb57055af1492591))
User-facing changes
- From JupyterLab 3.1, file documents and notebooks have collaborative
editing using the [Yjs shared editing framework](https://github.com/yjs/yjs).
Editors are not collaborative by default; to activate it, start JupyterLab
with the `--collaborative` flag. See full documentation on [collaboration](https://jupyterlab.readthedocs.io/en/latest/user/rtc.html).
- The undo/redo history in the notebook is now document-wide (tracking changes across all cells); the future verisions will enable restoring the previous behaviour of per-cell undo/redo.
- Table of Contents recieved multiple new features and settings described in the [user documentation](https://jupyterlab.readthedocs.io/en/latest/user/toc.html).
- The debugger recived many improvements, including basic support for evaluating code at a breakpoint, and for variable inspection.
- The closing bracket is no longer automatically added by default; the old behaviour can be re-enabled from the menu bar (`Settings` -> `Auto Close Brackets`) or from the Advanced Settings Editor.
- A new visual indicator was introduced to highlight cells in which the code changed in the editor since last execution:
<img alt="A GIF of the visual indicator showing up after editing a cell." src="https://user-images.githubusercontent.com/21197331/120619861-ae957d80-c45c-11eb-8640-b25b8b659ad4.gif">
- Many other new features were added as documented below.
