 > **Note**
-> StickyLand only supports `JupyterLab <= 3.6.4`. In June 2023, `JupyterLab 4.0` was released with a lot of breaking changes. I will update StickyLand to support `JupyterLab 4.0` when the official extension documentation is more polished. Any contribution to the [`lab4`](https://github.com/xiaohk/stickyland/tree/lab4) branch is greatly appreciated!
