JupyterLab Changelog

v4.3

JupyterLab 4.3 includes a number of new features (described below), bug fixes, and enhancements. This release is compatible with extensions supporting JupyterLab 4.0. Extension authors are recommended to consult the Extension Migration Guide which lists deprecations and changes to the public API.

Minimap

The virtual scrollbar now acts as a minimap and exposes information on whether a cell:

• is running/scheduled ([*]), idle ([ ]) or was already run (e.g. [1])
• was modified since it was last executed ("dirty") - orange background
• has an output that contains an error - red background
• is markdown/code ([ ]/[*]/[1] for code, nothing for markdown)
• how much text/code it contains

To enable the minimap, click on the hamburger icon (≡) which appears in the notebook's toolbar. If you do not see the hamburger icon, go to Settings → Notebook → Windowing mode and choose "full".

Fullscreen mode

JupyterLab now offers two ways to toggle the full screen mode from within the application:

• using the View → Appearance → Fullscreen Mode menu entry
• using a customizable shortcut, by default F11 (custom shortcuts are supported in Chrome, Safari and Edge)

File browser enhancements

The file browser now:

• supports resizing the columns and remembers the column sizes after reloading JupyterLab
• supports uploading folders by drag-and-drop
• supports navigation with a single click (opt-in)
• has the file filter collapsed by default (funnel icon), increasing the space available

Server-side execution and collaboration

JupyterLab 4.2 added the option for extensions to implement server-side execution, which preserves outputs created when the browser window is closed or disconnected. The server-side execution builds on the same shared models API as the real-time collaboration (RTC).

This release includes additional work, improving both the server-side execution and real-time collaboration (RTC) use cases:
