JupyterLab Changelog

v4.5

JupyterLab 4.5 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 encouraged to consult the Extension Migration Guide which lists deprecations and changes to the public API.

Performance and windowing

The default windowing mode is now contentVisibility which improves cell rendering and alleviates previously reported issues. The minimap can be enabled for all windowing modes and all notebooks via the Settings menu, or by toggling the minimap per notebook with the View -> Show Minimap option. Additional fixes improve layout containment and scrollbar behavior when working with long cells.

Notebook improvements

Saving large notebooks is now faster and more responsive thanks to streamed uploads and users can now open notebooks without starting a kernel, via the Open With context menu option.

Markdown support has been expanded for using grid and flex based layouts and the Table of Contents has been significantly improved to better handle markdown headings, fixing issues with HTML tags, comments, and horizontal lines.

Copying and pasting cells across browser tabs is now supported and the "Line Wrap" toggle in settings now correctly applies line wrapping to cells.

Other improvements include: restored scrolling to in-notebook links, manual saving support in collaborative mode, and improved performance and memory usage when streaming text outputs.

Debugger and Console improvements

The debugger's evaluate dialog has been replaced with an interactive console with syntax highlighting and code completion, and the variables panel now preserves its contents when switching editors. Selected breakpoints are now visually highlighted and breakpoints correctly handle empty lines and duplicate clicks. A visual indicator is displayed when the debugger is paused.

Debugger panels as well as console debugging panels now reference the cell execution count helping users relate breakpoints, call stacks and source code to the cells they originate from.

For the Log Console, users can now configure the default log level via settings, as well as customise the toolbar.

Terminal enhancements

The terminal now includes search functionality, with search highlights that adapt to theme changes.

Media and content support

JupyterLab now includes built-in audio and video viewers, allowing users to open audio and video files directly from within JupyterLab.

File browser enhancements

Uploaded files can auto-open, with controls for size limits and behavior, and a new allowFileUploads setting provides control over upload permissions.

There is now a menu option for creating new Python, R, or Julia files, and a “Select All” command has also been added, also accessible via the Ctrl + A keyboard shortcut.

Users can now configure file browser breadcrumbs through the settings editor options breadcrumbsLeftItems and breadcrumbsRightItems.

Updates to file dialogs and navigation have addressed column spacing, preferred-directory handling and double-click behavior.

Keyboard shortcuts and commands

Code fold and unfold commands have been added and shortcuts for these can be set in the settings editor.

The “Show Workspace Indicator” command has been added to the command palette and the “Send Code to Console” shortcut has been restored. The previous issue involving editing shortcuts on Safari loosing focus, has been resolved.

Settings

The settings editor now supports a toSkip configuration to hide specific plugins from view.

A new setting, addExtraLineOnCellMerge, allows to remove the extra line added when merging cells, which is expected behavior based on the classic notebook.

User interface and accessibility

JupyterLab can now automatically switch between light and dark themes when “Synchronize with System Settings” is enabled.

Dialog components display buttons and checkboxes on separate lines for better readability, and selections in the terminal under high-contrast themes have better visibility.

Keyboard navigation and tab order in the status bar has also been improved.

v4.4

JupyterLab 4.4 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 encouraged to consult the Extension Migration Guide which lists deprecations and changes to the public API.

Code console improvements

The code console prompt can now be positioned on the top, left, or right side of the console, in addition to the default bottom placement. The placement is persisted in the Prompt Cell Position setting.

The console toolbar now includes buttons to:

• Execute code
• Restart the kernel
• Clear the cells
• Switch the kernel

Additional settings for console behavior have been added:

• Clear Code Content on Execute (enabled by default) – When disabled, the code submitted for execution remains in the code editor, allowing for further edits.
• Hide Code Input – When enabled, only the execution output is shown in the console.
• Clear Cells on Execute – When enabled, only the last cell is displayed.

Toggling all the three new settings transforms the console into an interactive editor resembling an ephemeral notebook with a single cell.

Settings import and export

Settings can now be exported to overrides.json from the Settings Editor, which can be used to pre-configure defaults in deployments or to restore settings.

Workspace indicator

An opt-in workspace indicator is displayed on the top bar (next to the menu bar). It can be enabled in the Settings → View → Appearance → Show Workspace Indicator.

Support for collaboration without RTC: drive

Real time collaboration in previous versions of JupyterLab (which can be enabled by installing jupyter-collaboration package) was implemented by swapping the default JupyterLab file system drive to a collaborative drive with the RTC: prefix. This approach was incompatible with multiple extensions. JupyterLab 4.4 introduces the Content Providers API, which allows the next version of jupyter-collaboration to work without changing the drive prefix. This improves compatibility with extensions that do not support arbitrary drives.

Kernel subshells support

Kernel subshells, introduced in JEP 91, enable concurrent code execution in kernels that support them. When performing long-running computations (such as training a model), subshells enable users to:

• Use ipywidgets with updates displayed immediately
• Monitor kernel resource usage (e.g. memory usage)
• Invoke arbitrary commands (e.g., refine code for a subsequent cell) while maintaining live access to previously defined variables

Subshells are supported by ipykernel 7 (currently in alpha).

To create a subshell, open context menu (right-click) over a notebook using a kernel supporting subshells and select "New Subshell Console for Notebook". A new console panel will open allowing access to variables from the main session.

JupyterLab can automatically create subshells for comm messages if kernels support this feature. This enables concurrent execution of ipywidgets callbacks without requiring a user action. This behavior can be changed from the settings, with options to:

• disable that feature to not use subshells for comms
• (default) automatically create one subshell per comm-target (e.g. one subshell for all ipywidgets)
• automatically create one subshell per comm (this can lead to issues if creating many comms)

Context menu opt-out

The context menu, available under right mouse click in browsers, can now be disabled globally by toggling the Enable Context Menu option available in the Command Palette, or via the JSON Settings Editor in the Application Context Menu.

Slimmer status bar

The terminals counter no longer appears in the status bar if no terminals are open. The kernels counter can be disabled by toggling the "Show the status bar item" setting in "Running Terminals and Kernels" (code name showStatusBarItem).

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 <kbd>F11</kbd> (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:

• the intermediary state of streaming outputs is now optimized away preventing a memory leak when using shared models with long-running computations,
• the cell execution indicator ([*]) is now synchronized in the model, allowing collaborators to see that a cell is executed, and allowing server-side execution extensions to populate the state accordingly,
• the issue of spurious "File Change" dialog on save was addressed by enabling the collaborative models extension to update the document hash.

You can try these features by installing extensions:

• jupyter-server-nbmodel* provides server-side execution for jupyter-server,
• jupyter-collaboration provides the real-time collaboration features,
• jupyverse is an alternative server (a replacement for jupyter-server) which supports server-side execution.

* while jupyter-server-nbmodel is developed by maintainers of JupyterLab, as of the JupyterLab 4.3.0 release date it is not an official Project Jupyter extension.

Improved kernel and server interactions

The previous release enabled connecting to external kernels, such as those spawned by a third-party application like Blender. In this release the kernel selector dialog was improved to also show the external kernels.

The previous release improved the awareness of the kernel/kernel specification distinction by providing both tree and list view in the kernels sidebar panel, but only the tree view featured the kernel identifiers. In this release both the list and tree view show the kernel identifier stub.

A new toolbar button was added in the kernel allowing to shut down unused kernels (kernels with no widget attached).

The following dialog windows can now be dismissed or silenced:

• the "Server Connection Error" dialog now has an option to dismiss it for the duration of the session,
• the "Restart Kernel?" dialog now has an option to not ask again. This preference is persisted in settings ( skipKernelRestartDialog),

v4.2

Workspaces UI

It is now possible to switch and manage workspaces from within JupyterLab.

Recently opened/closed files

The jupyterlab-recents extension was integrated into JupyterLab.

Users are now able to:

• re-open recently used files from the main menu:

  

• re-open recently closed files from the sidebar:

  

• quickly jump to open tabs/recently closed files by using a new searchable modal dialog (press <kbd>Ctrl</kbd>+<kbd>Alt</kbd>+<kbd>A</kbd> to open the dialog, or click on the [↗] icon in the sidebar):

  

Full notebook windowing mode by default

Notebooks in the full windowing mode only render the visible cells, significantly improving the performance of the application. One limitation of full mode is that the search function in your browser may produce false negatives; using the JupyterLab search function is recommended. To revert to the behaviour from JupyterLab 4.1, go to Settings → Settings Editor → Notebook, scroll to "Windowing mode", and choose defer.

Improved Shortcuts Editor

Among the numerous improvements and bug fixes for the keyboard shortcuts editor:

• it is now possible to remove the default shortcuts,
• shortcuts are correctly sorted when using a language pack,
• shortcuts with different arguments are now correctly displayed as individual entries.

Dark high contrast theme

A new theme, JupyterLab Dark High Contrast, which is intended to benefit users with the need for higher contrast, following the WCAG AAA accessibility standard for color contrast. To select this theme, from the menu bar, choose Settings → Theme → JupyterLab Dark High Contrast. Please provide feedback and suggestions on further improvements to this theme.

Keyboard shortcuts improvements

Following feedback from users, implementation of certain shortcuts was moved from the CodeMirror editor to JupyterLab shortcut system, allowing for better integration:

• the shortcut for deleting a line was restored to <kbd>Ctrl</kbd>+<kbd>D</kbd> as in JupyterLab 3.x; the shortcut for extending (multi-cursor) selection was remapped to <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>D</kbd>. The <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>K</kbd> shortcut can also be used for deleting lines for compatibility with other editors.
• the shortcuts for toggling line comments (by default <kbd>Ctrl</kbd>+<kbd>/</kbd>) and block comments (by default <kbd>Alt</kbd>+<kbd>A</kbd>) can be customized in the Shortcuts Editor, enabling users of non-US keyboards to adjust the keybinding to one optimal on their keyboard layout. Please note that the block comment only works in languages which have a dedicated block comment syntax defined in the CodeMirror language data (e.g. C, JavaScript, but not Python). The line comment shortcut can be also used to comment out multiple lines.

v4.1

JupyterLab 4.1 includes a number of new features (described below), bug fixes, and enhancements for extension developers. 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.

Custom CSS

JupyterLab now supports automatic loading of custom CSS. Themes are the recommended way for customizing the JupyterLab look and feel, while custom CSS is intended for minor personal adjustments.

To opt in, start JupyterLab with the --custom-css flag. The location of the custom.css file is documented in the section on customizing the user interface.

`custom.css` is also available in Jupyter Notebook;
while similar selectors can be used for components shared between JupyterLab 4.1 and Jupyter Notebook 7.0,
there was a different set of selectors in Notebook 6 and older versions.
Users with the custom CSS file using the selectors from legacy Notebook versions
will need to update them and note that tutorials may refer to the selectors for the old Notebook versions.

Diagrams in Markdown

Matching GitHub-Flavoured Markdown, JupyterLab 4.1 now supports Mermaid diagrams. To create a mermaid diagram use the mermaid language specifier for a code block in a markdown cell or document, for example:

```mermaid
flowchart LR

A[Hard] -->|Text| B(Round)
B --> C{Decision}
C -->|One| D[Result 1]
C -->|Two| E[Result 2]
```

which renders as:

Inline completer

JupyterLab now supports completion presented as ghost text in the cell and file editors, allowing generative AI models to provide multi-line completions. The suggestions are provided by plugins implementing the IInlineCompletionProvider API; by default a single provider which uses kernel history is available.

The suggestions can be invoked as-you-type or manually using a configurable shortcut (by default <kbd>Alt</kbd> + <kbd>\</kbd>). The default keyboard shortcuts are displayed in the small widget shown when hovering over the ghost suggestion:

• <kbd>Alt</kbd> + <kbd>End</kbd> - accept suggestion
• <kbd>Alt</kbd> + <kbd>[</kbd> - previous suggestion
• <kbd>Alt</kbd> + <kbd>]</kbd> - next suggestion

To enable the inline suggestions based on the kernel history, go to Settings → Inline Completer → History provider → check the "enabled" checkbox.

In addition to the built-in history suggestions, the jupyter-ai extension can provide suggestions from supported models. The jupyter-ai integration with inline completer is available starting with the v2.10.0 release.

The Inline Completer API is still considered experimental and may be subject to changes, please share feedback!

Keyboard navigation improvements

Numerous improvements to keyboard navigation with focus on accessibility and usability are included in this release:

• the notebook cells now retain focus
• the focus can now be moved beyond the active notebook
• the toolbars can now be navigated using arrow keys

For more details, see this post on the Jupyter Blog.

Execution history in notebook

The code from previously executed cells can be used to populate empty cells, allowing to iterate on code from previous cells or even previous sessions (depending on how a specific kernel stores history).

To cycle between history items, press <kbd>Alt</kbd> + <kbd>Arrow Up</kbd> and <kbd>Alt</kbd> + <kbd>Arrow Down</kbd>.

To enable execution history, go to Settings → Notebook → check the "Kernel history access" checkbox.

This feature was already available in the console in previous releases; it only works with kernels supporting execution history requests. To clear the execution history, consult the documentation of the kernel you are using (e.g., IPython/ipykernel).

Opening files from tracebacks

Paths to code files detected in tracebacks returned by kernels on execution error are now turned into links. These links will open the corresponding file for editing, if it is in the Jupyter root directory, or they will open a read-only preview if the file is outside of the root directory and the active kernel supports the debugger.

Error indicator in the table of contents

When a cell fails during execution, an error indicator will be displayed by the corresponding heading, increasing awareness of the notebook state and enabling users to quickly navigate to the cell which requires attention.

Plugin Manager

Individual plugins can now be disabled or enabled from a new Plugin Manager user interface. Each extension is composed of one or more plugins, and plugins form the basis of JupyterLab itself, thus the plugin manager enables more extensive customization of the JupyterLab experience.

This feature is intended for advanced users and is documented in depth in the documentation.

Administrators may want to lock specific plugins if they are required for any reason; this will prevent users from disabling the plugins via Plugin Manager and remote API calls. The Plugin Manager itself can be disabled using the CLI.

Virtual scrollbar for notebook in windowed mode

The windowed notebook received an optional scrollbar delineating the active cell and selected cells. Users can jump to a specific cell.

To enable the virtual scrollbar, go to Settings → Notebook → Windowing mode, choose "full", and click on the hamburger icon (≡) which appears in the notebook's toolbar.

Virtual scrollbar is considered experimental, please share feedback!

Notifications

JupyterLab 3.6 added a notification center which so far was only used for announcements and version update notifications (both opt-in). JupyterLab 4.1 adds two notifications to guide users in potentially confusing situations:

• when a user attempts to save a read-only document, a transient notification suggesting using "save as" is displayed
• when a user attempts to execute a cell before a slow-starting kernel has initialized, a notification is shown to indicate that the cell cannot be yet executed (this is opt-in and needs to be enabled in settings)

Full notebook windowing mode improvements

Notebooks in the full windowing mode only render the visible cells, significantly improving the performance of the application. Numerous improvements for the full windowing mode behaviour (such as scrolling, search, rendering, and navigation) are included in this release (see the list of issues in #15258 for details).

The windowing mode is still experimental and known issues remain to be solved
([#15415](https://github.com/jupyterlab/jupyterlab/issues/15415), [#15465](https://github.com/jupyterlab/jupyterlab/issues/15465),  [#15594](https://github.com/jupyterlab/jupyterlab/issues/15594)).
In addition, a sporadic regression in cell ordering ([#15610](https://github.com/jupyterlab/jupyterlab/issues/15610)) was observed in 4.1 beta,
and remains to be fixed, pending reports from users willing to test the windowing mode in JupyterLab 4.1 to help create reproducible steps that would enable fixing this issue.

Users who already enabled this mode in previous versions are advised to evaluate the benefits of fixes included in 4.1 against regressions linked above before deciding to upgrade.

Search improvements

• The search box will now grow automatically to accommodate longer text
• Search in selection can now be toggled using <kbd>Alt</kbd> + <kbd>L</kbd> and automatic search in selection can be configured in settings
• Tooltips with shortcuts were added to the buttons in the search box to improve discoverability of the shortcuts

Miscellaneous

• The current theme (dark/light) can now be synced with the browser/system preference (Settings menu → Theme → Synchronise with System Settings)
• A blue "read-only" status indicator is now displayed in the toolbar of documents which cannot be saved because their model is read-only.
• Native support for viewing jsonl/ndjson files was added
• Collapsing of breadcrumbs in the File Browser can be disabled in File Browser settings
• Extension manager can now use a HTTP proxy for fetching extensions

Moved plugins

Some internal JupyterLab plugins have been re-organized to allow for better flexibility for deployments and downstream applications like Notebook 7. This might affect users that disable specific plugins with the jupyter labextension disable command or the disabledExtensions config option.

• The help:open command is not defined in the @jupyterlab/help-extension:resources plugin anymore, but has been moved to a new @jupyterlab/help-extension:open plugin instead.

v4.0

4.0.0 - Highlights

Below are the major highlights in JupyterLab 4.0.0.

New text editor

CodeMirror, the text editor used for cells and file editors, has been updated to CodeMirror 6. This brings important accessibility and performance improvements as well as better customization capabilities. We have also improved the editor settings. Previously, users had to customize settings separately for each type of cell, the file editor, and the console editor. Now, you can change your settings in one place. It is now easier to use the default settings for all editors and to change some settings for specific cases. For example, you can now hide line numbers only for markdown cells.

Developers can now provide editor extensions, like themes and programming language parsers, through new application registries.

New extension manager

Starting with JupyterLab 3, extensions can be installed via Python packages (or other providers of prebuilt extensions).

In JupyterLab 4, building on this feature, the Extension Manager now includes extensions from pypi.org. This removes the build step from installation of extension when using Extension Manager.

Developers can provide an alternative package repository to display their own set of extensions.

Improved document search

The Search and Replace functionality has been improved with new features when searching in a notebook:

• Highlight matches in rendered markdown cells
• Search in selection
• Multi-line search
• Replace using regex capture-group references
• Replace while preserving case

UI improvements

Some new elements have been added or changed in the UI:

• Rework the running kernels section
• "Add a new cell" button at the bottom of a notebook
• Dialog to display keyboard shortcuts as in the Classic Notebook (use <kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>H</kbd>)
• Display the first line of cell input and outputs when they are collapsed

Accessibility improvements

JupyterLab is not yet fully accessible. Currently, we are focused on making Notebook 7 accessible. A big part of the code is shared, though, and the following accessibility improvements are in JupyterLab 4:

• Improved focus and keyboard navigation in the file browser
• More ARIA roles and labels were added to UI elements
• Main menu collapses to a hamburger menu if there is not enough space to display all items.

Performance enhancements

JupyterLab is now faster, thanks to the following improvements:

• CSS rules optimization: CSS selectors have been optimized to improve web browser performance when many elements are present on a page.
• Upgrade to CodeMirror 6: Especially for notebooks with many cells, the new CodeMirror version is far more efficient than the previous version. Large notebooks should load more quickly.
• Upgrade to MathJax 3: The mathematical equations renderer library has been been upgraded from v2 to v3 allowing faster rendering.
• Notebook windowing: By rendering only the parts of a notebook that fit in the web browser viewport, JupyterLab is much more efficient. See an important note below.

Notebook windowing might add side effects for example if some cell outputs are displaying iframes. Therefore it is not yet the default value. But we recommend user to switch to it and report bugs to help us polish it. To test it, you need to set the user setting Notebook > Windowing mode to full. If you have issues with notebook rendering, try changing back to defer or none. (none should be used as a last resort, because it disables all optimizations.)

Real Time Collaboration

JupyterLab 3.6 already made significant improvements to the Real Time Collaboration (RTC) feature. The feature is now in a separate repository: jupyter_collaboration. The rationale is to limit the dependencies for users who don't need RTC. Separating RTC also helps organizations using JupyterLab that do not meet the specific requirements regarding file content management.

To enable RTC, install the jupyter-collaboration package with either pip or conda.

• with pip: pip install "jupyter-collaboration>=1.0.0a0"
• with conda: not yet available

RTC highlights in the standalone jupyter-collboration package, version 1.0.0, include:

• Support for displaying multiple cursors and selections
• Support for registration of new shared model types

For developers

Here are the main tool updates that will benefit extension authors and developers:

• TypeScript v5
• Yarn v3
• React v18
• Lumino v2

We recommend using Node.js v18 or newer, because older versions will reach end of life in 2023 or earlier (see Node release schedule).

To ease code migration to JupyterLab 4, developers should review the migration guide. A few existing extensions have already been migrated and can be used as examples:

• the JupyterLab Extensions by Examples
• the Jupyter MIME type renderers
