(Full Changelog)

User-facing changes#

  • From JupyterLab 3.1, file documents and notebooks have collaborative editing using the Yjs shared editing framework. Editors are not collaborative by default; to activate it, start JupyterLab with the --collaborative flag. See full documentation on collaboration.

  • 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.

  • 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: A GIF of the visual indicator showing up after editing a cell.

  • Many other new features were added as documented below.

v3.0.0#

User-facing changes#

Extensions can be installed without building JupyterLab with NodeJS#

In JupyterLab 3.0, a new recommended way of distributing and installing extensions as Python pip or conda packages is available. Installing such extensions does not require rebuilding JupyterLab and does not require having NodeJS installed. The previous way of distributing extensions as npm packages requiring rebuilding JupyterLab is still available as well. See the documentation for more details.

The JupyterLab interface supports multiple languages#

JupyterLab now provides the ability to set the display language of the user interface. See the documentation for more details.

A new visual debugger#

JupyterLab now ships with a debugger front-end by default, available for kernels that support the new debugging protocol. See the documentation for more details.

Improvements to Simple Interface mode and Mobile#

The Simple Interface mode (previously Single Document Mode) is now more streamlined. JupyterLab now supports showing the current file in use in the browser URL bar, similar to the classic Jupyter Notebook.

Table of Contents is now in core#

The popular Table of Contents extension is now part of core JupyterLab. This core extension makes it easy to see an outline view of notebooks and other documents.

Visual filter in file browser#

The file browser now has a filter input which filters the list of files using the same fuzzy matching as the command palette.

Property inspector moved to right sidebar#

The default interface for JupyterLab now has system-wide sidebar panes on the left side and sidebar panels that interact with a specific document (such as the debugger or notebook property inspector) on the right side. As always, you can move panes between the left and right sidebars (right click on the sidebar icon, or change it in Advanced Settings).

Command Palette#

The command palette is now a floating window that appears on top of your JupyterLab workspace. This enables users to quickly invoke a command while keeping the sidebar closed or switching sidebar panels. The command palette can be put back into the sidebar by adjusting the default in Advanced Settings.

Jupyter Server#

JupyterLab 3.0 now depends on Jupyter Server, which is a new Jupyter project based on the server portion of the classic Notebook server. See the Migration Guide to migrate custom notebook configuration to Jupyter Server.

For Developers#

Prebuilt Extensions#

Users will typically consume prebuilt extensions, which are Python packages with static assets built using JupyterLab. See the updated APOD tutorial for the workflow of creating a prebuilt extension from scratch. For existing extensions, there is a new python -m jupyterlab.upgrade_extension script that can be used to upgrade extensions. The script will update the relevant dependencies and add the boilerplate to create the Python package. For extensions that already contained Python packages (typically server extensions), the files are not overwritten, and some manual copying of content is required. See the example, which used this script heavily. There are two highlighted commits that demonstrate upgrading a server extension. Prebuilt extensions are also known as federated extensions in the changes below, since they use the federated module capability in Webpack 5.

  • Better handling of extensions that provide both prebuilt and source extensions. (#9489, #9277)

  • Document new page config conventions (#9454, #9240)

  • Use stylemodule in prebuilt extensions (#9460, #9459)

  • Update style-loader and mini-css-extract-plugin (#9451)

  • Use a more explicit stylemodule key for js css imports (#9427, #9423)

  • Ignore source packages when building or loading jupyterlab if there is a prebuilt package (#9424, #9277)
