Performance and windowing#

The default windowing mode is nowcontentVisibility which improves cell rendering andalleviates previously reported issues. The minimap can be enabled for all windowing modesand all notebooks via theSettings menu, or by toggling the minimap per notebook withtheView ->ShowMinimap option. Additional fixes improve layout containment andscrollbar behavior when working with long cells.

Notebook improvements#

Saving large notebooks is now faster and more responsive thanks to streamed uploadsand users can now open notebooks without starting a kernel, via theOpenWithcontext menu option.

Markdown support has been expanded for using grid and flex based layouts and theTable 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, manualsaving support in collaborative mode, and improved performance and memory usagewhen streaming text outputs.

Debugger and Console improvements#

The debugger’s evaluate dialog has been replaced with an interactive console with syntaxhighlighting and code completion, and the variables panel now preserves its contents whenswitching editors. Selected breakpoints are now visually highlighted and breakpointscorrectly handle empty lines and duplicate clicks. A visual indicator is displayedwhen the debugger is paused.

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

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 totheme changes.

Media and content support#

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

File browser enhancements#

Uploaded files can auto-open, with controls for size limits and behavior, anda newallowFileUploads 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 theCtrl+A keyboard shortcut.

Users can now configure file browser breadcrumbs through the settings editoroptionsbreadcrumbsLeftItems andbreadcrumbsRightItems.

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 beset in the settings editor.

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

Settings#

The settings editor now supports atoSkip configuration to hidespecific plugins from view.

A new setting,addExtraLineOnCellMerge, allows to remove the extra line addedwhen 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 betterreadability, and selections in the terminal under high-contrast themes havebetter visibility.

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

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 CellPosition 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 editorresembling an ephemeral notebook with a single cell.

Settings import and export#

Settings can now be exported tooverrides.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 enabledin the Settings → View → Appearance → Show Workspace Indicator.

Support for collaboration withoutRTC: 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 systemdrive to a collaborative drive with theRTC: prefix.This approach was incompatible with multiple extensions.JupyterLab 4.4 introduces the Content Providers API, which allows the next version ofjupyter-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 inJEP 91,enable concurrent code execution in kernels that support them.When performing long-running computations (such as training a model), subshells enable users to:

• Useipywidgets 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 byipykernel 7 (currently in alpha).

To create a subshell, open context menu (right-click)over a notebook using a kernel supporting subshellsand 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 ofipywidgets 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 allipywidgets)

• 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 globallyby toggling theEnableContextMenu 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” settingin “Running Terminals and Kernels” (code nameshowStatusBarItem).

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 theView →Appearance →FullscreenMode menu entry

• using a customizable shortcut, by defaultF11 (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 preservesoutputs 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 boththe 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 forjupyter-server,

• jupyter-collaboration provides the real-time collaboration features,

• jupyverse is an alternative server (a replacement forjupyter-server) which supports server-side execution.

* whilejupyter-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),

Workspaces UI#

It is now possible to switch and manageworkspaces from within JupyterLab.

Recently opened/closed files#

Thejupyterlab-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 (pressCtrl+Alt+A to open the dialog, or click on the [↗] icon in the sidebar):

  

Full notebook windowing mode by default#

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

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 toCtrl+D as in JupyterLab 3.x; the shortcut for extending (multi-cursor) selection was remapped toCtrl+Shift+D. TheCtrl+Shift+K shortcut can also be used for deleting lines for compatibility with other editors.

• the shortcuts for toggling line comments (by defaultCtrl+/) and block comments (by defaultAlt+A) 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.

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 thecustom.css file is documented in the section oncustomizing the user interface.

Diagrams in Markdown#

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

```mermaidflowchart LRA[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 theIInlineCompletionProvider 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 defaultAlt +\).The default keyboard shortcuts are displayed in the small widget shown when hovering over the ghost suggestion:

• Alt +End - accept suggestion

• Alt +[ - previous suggestion

• Alt +] - 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,thejupyter-ai extension can providesuggestions from supported models.Thejupyter-ai integration with inline completer is available starting with thev2.10.0 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, seethis 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, pressAlt +Arrow Up andAlt +Arrow Down.

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 thedocumentation.

Administrators may want tolock 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 bedisabled 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 thefull 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).

Search improvements#

• The search box will now grow automatically to accommodate longer text

• Search in selection can now be toggled usingAlt +L 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 thejupyterlabextensiondisable command or thedisabledExtensions config option.

• Thehelp: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.
