3.1.0#

(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.

Find and Replace#

We have added first class support for find and replace across JupyterLab. It is currently supported in notebooks and text files and is extensible for other widgets who wish to support it. (#6350, #6322, #6301, #6282, #6256, #6241, #6237, #6159, #6081, #6155, #6094, #6024, #5937, #5795, #1074)

Status Bar#

We have integrated the JupyterLab Status Bar package package into the core distribution. Extensions can add their own status to it as well (#5577, #5525 #5990, #5982, #5514, #5508, #5352).

JupyterHub Integration#

  • The launcher now updates when the kernels change on the server (#5904, #5676)

  • Retain cell auto scroll behavior even when a cell output is cleared (#5817, #4028)

  • If you link to a relative path that is not a file in a markdown cell, this will now be preserved instead of changing it to a file URL (#5814)

  • Send complete statements instead of current lines when stepping through code in a cell (#6515, #6063)

  • Description list styles (dl, dt, dd) are improved to be consistent with the nteract project (#5682, #2399)

Settings#

  • The settings system has been rewritten (#5470, #5298) and now uses json5 as the syntax, which supports comments and other features for better human readability (#6343, #6199).

  • The keyboard shortcut system has been rewritten and now displays a list of system commands in the settings comments (#5812, #5562).

There are new settings for many following items, including:

Command Line Changes#

  • Installing extensions will be quieter and adds a --debug to extension installing (#6567, #6499, #5986)

  • We now support running JupyterLab when its application directory is a symlink (#6240, #6166)

  • Add --all flag to labextension uninstall to remove all extensions (#6058, #6006)

  • Adds the ability to override the base URLs from the config (#5518, #5503)

  • Updates to workspaces CLI command (#6473, #5977, #6276, #6234, #6210, #5975, #5695, #5694)

Extension Development Changes#

  • We have rewritten how extensions provide keyboard shortcuts and interact with the settings system. If you previously defined keyboard shortcuts or used the settings mechanism, you will need to update your extension (#5470, #5298)

  • We have renamed the plugin type from JupyterLabPlugin to JupyterFrontEndPlugin. The application arg is also renamed from JupyterLab to JupyterFrontEnd and some its functionality has been moved to a separate ILabShell plugin (#5845, #5919)

  • The lab shell addToMainArea, addToLeftArea, addToTopArea, addToRightArea, and addToBottomArea functions have been replaced with a single add() function that takes the area as an argument. Replace addToMainArea(widget, options) with add(widget, 'main', options), etc. (#5845)

  • Rename pageUrl to appUrl in the server connection (#6509, #6508, #6585, #6584)

  • MainAreaWidget instances now forward update requests to their content (#6586, #6571)

  • The theme data attributes are renamed and moved to the document body element. If you are relying on these attributes in CSS to conditionally style based on the theme, you should update their names. For example data-theme-light is now data-jp-theme-light. (#6566, #6554)

  • Extensions which require CSS should no longer import their CSS files into their Javascript files. Instead, they should specify a root CSS file in the style attribute in their package.json, and JupyterLab will automatically import that CSS file. (#6533, #6530, #6395, #6390)

  • Dialog.prompt has been replaced by a number of type-specific dialogs such as InputDialog.getString, InputDialog.getBoolean, etc. (#6522, #6378, #6327, #6326)

  • When a RenderMime widget is re-rendered, the default behavior is to remove any existing content in the DOM. This can be overridden if needed. (#6513, #6505, #6497)

  • We have updated our internal TypeScript version to 3.5.1 and our compile target to ES2017. Extensions may need to upgrade their TypeScript version and target as well. (#6440, #6224)

  • We have updated the typings for some of the Kernel messages so that they better match the spec. (#6433)

  • A connectionFailure signal has been added to some of the manager classes, which can be used to detect when a connection to the server is lost (#6399, #6176, #3324)

  • Add rate limiting and polling utilities to coreutils to use for throttling and debouncing of API requests (#6345, #6346, #6401, #6305, #6157, #6192, #6186, #6141, #3929, #6141, #3929, #6186, #6192, #6401 ,#6305, #6157)

  • Require session when instantiating terminal widget (#6339, #5061)

  • Provides a signal to see what items are opened in a directory listing (#6270, #6269)

  • Ads the ability to add widget above the main work area to a top header area (#5936)

  • Renames contextMenuFirst to contextMenuHitTest in the JupyterFrontEnd (#5932)

  • Removes the initialCommand arg from the terminal creation command. (#5916)

  • Adds --jp-code-cursor-width0, --jp-code-cursor-width1, and --jp-code-cursor-width2 variables to the themes to support changing the cursor width if you change the font size (#5898)

  • Adds the ability to insert a new item to the toolbar before or after another item (#5896, #5894)

  • Adds the ability for extensions to register new CodeMirror modes (#5829)

  • We have removed the JUPYTERLAB_xxx_LOADER Webpack loaders, instead you should use the loader directly in the URL as Webpack supports it (#5709, #4406)

  • Adds the ability to handle fragments for document widgets (#5630, #5599)

  • We have added a @jupyterlab/ui-components package that contains reusable React components to be used internally and in extensions. Feel free to use this to create extension UIs with consistent styles (#5538)

  • The showErrorMessage function now lets you customize the buttons it uses (#5513)

  • We now provide helpers for using React components within JupyterLab. If you were previously using ReactElementWidget you should switch to using ReactWidget. (#5479, #5766, #6595, #6595)

  • The share link command has been moved to its own extension so that it can be overridden (#5460, #5388)

  • Creating a new services session now requires passing a kernel model instead of a kernel instance (#6503, #6142)

  • We upgraded the Webpack raw file loader. The new version of the raw loader exports ES2015 modules, so this may require changes in extensions that import files using the raw loader. For example, if you did require('myfile.md') to get the content of myfile.md as a string, you now should import it using ES2015 import syntax, or use require(\'myfile.md\').default.

  • Widget factories now can support custom cloning behavior from an optional source widget (#6060, #6044)

  • We have renamed the type InstanceTracker to WidgetTracker (#6569).

  • In order to add widgets to the main area (e.g. as in the old XKCD extension tutorial), the correct syntax is now app.shell.add(widget) or app.shell.add(widget, 'main'), see here.

v0.35.0#

October 3, 2018#

  • Fix notebook cell dropdown legibility in a dark theme. (#5168)

Bug fixes#

  • Various save options in the file menu and toolbar are now disabled when a file is not writable. (#5376, #5391)

  • Kernel selector dialog no longer cuts off kernel names. (#5260, #5181)

  • Fix focus issues with the toolbar. (#5344, #5324, #2995, #5328)

  • Table alignment is now respected in Markdown. (#5301, #3180)

  • Fix syntax highlighting for Markdown lists. (#5297, #2741)

  • Use the current filebrowser instead of the default one for various commands. (#5390)

  • Fix escaping in link handling to conform to Markdown syntax. This means that spaces in link references now need to be encoded as %20. (#5383, #5340, #5153)

Build system#

  • Use Typescript 3.1. (#5360)

  • Use Lerna 3.2.1. (#5262)

  • Node >=6.11.5 is now required. (#5227)

v0.34.0#

August 18, 2018#

See the JupyterLab 0.34.0 milestone on GitHub for the full list of pull requests and issues closed.

Key Features#

  • Notebooks, consoles, and text files now have access to completions for local tokens.

  • Python 3.5+ is now required to use JupyterLab. Python 2 kernels can still be run within JupyterLab.

  • Added the pipe (|) character as a CSV delimiter option.

  • Added “Open From Path…”” to top level File menu.

  • Added “Copy Download Link” to context menu for files.

Changes for Developers#

  • Notebooks, consoles, and text files now have access to completions for local tokens. If a text file has a running kernel associated with its path (as happens with an attached console), it also gets completions and tooltips from that kernel. (#5049)

  • The FileBrowser widget has a new constructor option refreshInterval, allowing the creator to customize how often the widget polls the storage backend. This can be useful to prevent rate-limiting in certain contexts. (#5048)

  • The application shell now gets a pair of CSS data attributes indicating the current theme, and whether it is light or dark. Extension authors can write CSS rules targeting these to have their extension UI elements respond to the application theme. For instance, to write a rule targeting whether the theme is overall light or dark, you can use

    [data-theme-light='true'] your-ui-class {
  background-color: white;
}
[data-theme-light='false'] your-ui-class {
  background-color: black;
}

    The theme name can also be targeted by writing CSS rules for data-theme-name. (#5078)

  • The IThemeManager interface now exposes a signal for themeChanged, allowing extension authors to react to changes in the theme. Theme extensions must also provide a new boolean property isLight, declaring whether they are broadly light colored. This data allows third-party extensions to react better to the active application theme. (#5078)

  • Added a patch to update the uploads for each FileBrowserModel instantly whenever a file upload errors. Previously, the upload that erred was only being removed from uploads upon an update. This would allow the status bar component and other extensions that use the FileBrowserModel to be more precise. (#5077)

  • Cell IDs are now passed in the shell message as part of the cell metadata when a cell is executed. This helps in developing reactive kernels. (#5033)

  • The IDs of all deleted cells since the last run cell are now passed as part of the cell metadata on execution. The IDs of deleted cells since the last run cell are stored as deletedCells in NotebookModel. This helps in developing reactive kernels. (#5037)

  • The ToolbarButton in apputils has been refactored with an API change and now uses a React component ToolbarButtonComponent to render its children. It is now a div with a single button child, which in turn as two span elements for an icon and text label. Extensions that were using the className options should rename it as iconClassName. The className options still exists, but it used as the CSS class on the button element itself. The API changes were done to accommodate styling changes to the button. (#5117)

  • The Toolbar.createFromCommand function has been replaced by a dedicated ToolbarButton subclass called CommandToolbarButton, that wraps a similarly named React component. (#5117)

  • The design and styling of the right and left sidebars tabs has been improved to address #5054. We are now using icons to render tabs for the extensions we ship with JupyterLab and extension authors are encouraged to do the same (text labels still work). Icon based tabs can be used by removing widget.caption and adding widget.iconClass = '<youriconclass> jp-SideBar-tabIcon';. (#5117)

  • The style of buttons in JupyterLab has been updated to a borderless design. (#5117)

  • A new series of helper CSS classes for stying SVG-based icons at different sizes has been added: jp-Icon, jp-Icon-16, jp-Icon-18, jp-Icon-20.

  • The rank of the default sidebar widget has been updated. The main change is giving the extension manager a rank of 1000 so that it appears at the end of the default items.

  • Python 3.5+ is now required to use JupyterLab. Python 2 kernels can still be run within JupyterLab. (#5119)

  • JupyterLab now uses yarn 1.9.4 (aliased as jlpm), which now allows uses to use Node 10+. (#5121)

  • Clean up handling of baseUrl and wsURL for PageConfig and ServerConnection. (#5111)

Other Changes#

  • Added the pipe (|) character as a CSV delimiter option. (#5112)

  • Added Open From Path... to top level File menu. (#5108)

  • Added a saveState signal to the document context object. (#5096)

  • Added “Copy Download Link” to context menu for files. (#5089)

  • Extensions marked as deprecated are no longer shown in the extension manager. (#5058)

  • Remove In and Out text from cell prompts. Shrunk the prompt width from 90px to 64px. In the light theme, set the prompt colors of executed console cells to active prompt colors and reduced their opacity to 0.5. In the dark theme, set the prompt colors of executed console cells to active prompt colors and set their opacity to 1. (#5097 and #5130)

Bug Fixes#

  • Fixed a bug in the rendering of the “New Notebook” item of the command palette. (#5079)

  • We only create the extension manager widget if it is enabled. This prevents unnecessary network requests to npmjs.com. (#5075)

  • The running panel now shows the running sessions at startup. (#5118)

  • Double clicking a file in the file browser always opens it rather than sometimes selecting it for a rename. (#5101)

v0.33.0#

July 26, 2018#

See the JupyterLab 0.33.0 milestone on GitHub for the full list of pull requests and issues closed.

Key Features:#

No longer in beta#

In JupyterLab 0.33, we removed the “Beta” label to better signal that JupyterLab is ready for users to use on a daily basis. The extension developer API is still being stabilized. See the release blog post for details. (#4898, #4920)

Workspaces#

We added new workspace support, which enables you to have multiple saved layouts, including in different browser windows. See the workspace documentation for more details. (#4502, #4708, #4088, #4041 #3673, #4780)

Keyboard shortcuts#

  • “Save As…” given the keyboard shortcut Ctrl/Cmd Shift S. (#4560)

  • “Run All Cells” given the keyboard shortcut Ctrl/Cmd Shift Enter. (#4558)

  • “notebook:change-to-cell-heading-X” keyboard shortcuts (and commands) renamed to “notebook:change-cell-to-heading-X” for X=1…6. This fixes the notebook command-mode keyboard shortcuts for changing headings. (#4430)

  • The console execute shortcut can now be set to either Enter or Shift Enter as a Console setting. (#4054)

Command palette items#

  • “Notebook” added to the command palette to open a new notebook. (#4812)

  • “Run Selected Text or Current Line in Console” added to the command palette to run the selected text or current line from a notebook in a console. A default keyboard shortcut for this command is not yet provided, but can be added by users with the notebook:run-in-console command. To add a keyboard shortcut Ctrl G for this command, use the “Settings” | “Advanced Settings Editor” menu item to open the “Keyboard Shortcuts” advanced settings, and add the following JSON in the shortcut JSON object in the User Overrides pane (adjust the actual keyboard shortcut if you wish). (#3453, #4206, #4330)

    {
  "command": "notebook:run-in-console",
  "keys": ["Ctrl G"],
  "selector": ".jp-Notebook.jp-mod-editMode"
}

  • The command palette now renders labels, toggled state, and keyboard shortcuts in a more consistent and correct way. (#4533, #4510)

Settings#

  • “fontFamily”, “fontSize”, and “lineHeight” settings added to the text editor advanced settings. (#4673)

  • Solarized dark and light text editor themes from CodeMirror. (#4445)

Larger file uploads#

  • Support for larger file uploads (>15MB) when using Jupyter notebook server version >= 5.1. (#4224)

Extension management and installation#

  • New extension manager for installing JupyterLab extensions from npm within the JupyterLab UI. You can enable this from the Advanced Settings interface. (#4682, #4925)

  • Please note that to install extensions in JupyterLab, you must use NodeJS version 9 or earlier (i.e., not NodeJS version 10). We will upgrade yarn, with NodeJS version 10 support, when a bug in yarn is fixed. (#4804)

Interface changes#

  • Wider tabs in the main working area to show longer filenames. (#4801)

  • Initial kernel selection for a notebook or console can no longer be canceled: the user must select a kernel. (#4596)

  • Consoles now do not display output from other clients by default. A new “Show All Kernel Activity” console context menu item has been added to show all activity from a kernel in the console. (#4503)

  • The favicon now shows the busy status of the kernels in JupyterLab. (#4361, #3957, #4966)

Renderers#

  • JupyterLab now ships with a Vega4 renderer by default (upgraded from Vega3). (#4806)

  • The HTML sanitizer now allows some extra tags in rendered HTML, including kbd, sup, and sub. (#4618)

  • JupyterLab now recognizes the .tsv file extension as tab-separated files. (#4684)

  • Javascript execution in notebook cells has been re-enabled. (#4515)

Changes for developers#

  • A new signal for observing application dirty status state changes. (#4840)

  • A new signal for observing notebook cell execution. (#4740, #4744)

  • A new anyMessage signal for observing any message a kernel sends or receives. (#4437)

  • A generic way for different widgets to register a “Save with extras” command that appears in the File menu under save. (#3981)

  • A new API for removing groups from a JupyterLab menu. addGroup now returns an IDisposable which can be used to remove the group. removeGroup has been removed. (#4890)

  • The Launcher now uses commands from the application CommandRegistry to launch new activities. Extension authors that add items to the launcher will need to update them to use commands. (#4757)

  • There is now a top-level addToBottomArea function in the application, allowing extension authors to add bottom panel items like status bars. (#4752)

  • Rendermime extensions can now indicate that they are the default rendered widget factory for a file-type. For instance, the default widget for a markdown file is a text editor, but the default rendered widget is the markdown viewer. (#4692)

  • Add new workspace REST endpoints to jupyterlab_server and make them available in @jupyterlab/services. (#4841)

  • Documents created with a mimerenderer extension can now be accessed using an IInstanceTracker which tracks them. Include the token IMimeDocumentTracker in your plugin to access this. The IInstanceTracker interface has also gained convenience functions find and filter to simplify iterating over instances. (#4762)

  • RenderMime render errors are now displayed to the user. (#4465)

  • getNotebookVersion is added to the PageConfig object. (#4224)

  • The session kernelChanged signal now contains both the old kernel and the new kernel to make it easy to unregister things from the old kernel. (#4834)

  • The connectTo functions for connecting to kernels and sessions are now synchronous (returning a connection immediately rather than a promise). The DefaultSession clone and update methods are also synchronous now. (#4725)

  • Kernel message processing is now asynchronous, which guarantees the order of processing even if a handler is asynchronous. If a kernel message handler returns a promise, kernel message processing is paused until the promise resolves. The kernel’s anyMessage signal is emitted synchronously when a message is received before asynchronous message handling, and the iopubMessage and unhandledMessage signals are emitted during asynchronous message handling. These changes mean that the comm onMsg and onClose handlers and the kernel future onReply, onIOPub, and onStdin handlers, as well as the comm target and message hook handlers, may be asynchronous and return promises. (#4697)

  • Kernel comm targets and message hooks now are unregistered with removeCommTarget and removeMessageHook, instead of using disposables. The corresponding registerCommTarget and registerMessageHook functions now return nothing. (#4697)

  • The kernel connectToComm function is synchronous, and now returns the comm rather than a promise to the comm. (#4697)

  • The KernelFutureHandler class expectShell constructor argument is renamed to expectReply. (#4697)

  • The kernel future done returned promise now resolves to undefined if there is no reply message. (#4697)

  • The IDisplayDataMsg is updated to have the optional transient key, and a new IUpdateDisplayDataMsg type was added for update display messages. (#4697)

  • The uuid function from @jupyterlab/coreutils is removed. Instead import UUID from @phosphor/coreutils and use UUID.uuid4() . (#4604)

  • Main area widgets like the launcher and console inherit from a common MainAreaWidget class which provides a content area (.content) and a toolbar (.toolbar), consistent focus handling and activation behavior, and a spinner displayed until the given reveal promise is resolved. Document widgets, like the notebook and text editor and other documents opened from the document manager, implement the IDocumentWidget interface (instead of DocumentRegistry.IReadyWidget), which builds on MainAreaWidget and adds a .context attribute for the document context and makes dirty handling consistent. Extension authors may consider inheriting from the MainAreaWidget or DocumentWidget class for consistency. Several effects from these changes are noted below. (#3499, #4453)

    • The notebook panel .notebook attribute is renamed to .content.

    • The text editor is now the .content of a DocumentWidget, so the top-level editor widget has a toolbar and the editor itself is widget.content.editor rather than just widget.editor.

    • Mime documents use a MimeContent widget embedded inside of a DocumentWidget now.

    • Main area widgets and document widgets now have a revealed promise which resolves when the widget has been revealed (i.e., the spinner has been removed). This should be used instead of the ready promise.

Changes in the JupyterLab code infrastructure include:

  • The JupyterLab TypeScript codebase is now compiled to ES2015 (ES6) using TypeScript 2.9. We also turned on the TypeScript esModuleInterop flag to enable more natural imports from non-es2015 JavaScript modules. With the update to ES2015 output, code generated from async/await syntax became much more manageable, so we have started to use async/await liberally throughout the codebase, especially in tests. Because we use Typedoc for API documentation, we still use syntax compatible with TypeScript 2.7 where Typedoc is used. Extension authors may have some minor compatibility updates to make. If you are writing an extension in TypeScript, we recommend updating to TypeScript 2.9 and targeting ES2015 output as well. (#4462, #4675, #4714, #4797)

  • The JupyterLab codebase is now formatted using Prettier. By default the development environment installs a pre-commit hook that formats your staged changes. (#4090)

  • Updated build infrastructure using webpack 4 and better typing. (#4702, #4698)

  • Upgraded yarn to version 1.6. Please note that you must use NodeJS version 9 or earlier with JupyterLab (i.e., not NodeJS version 10). We will upgrade yarn, with NodeJS version 10 support, when a bug in yarn is fixed. (#4804)

  • Various process utilities were moved to jupyterlab_server. (#4696)
