Changelog

A summary of changes in the Jupyter notebook. For more detailed information, see GitHub.

Tip

Use pip install notebook --upgrade or conda upgrade notebook to upgrade to the latest release.

We strongly recommend that you upgrade pip to version 9+ of pip before upgrading notebook.

Tip

Use pip install pip --upgrade to upgrade pip. Check pip version with pip --version.

5.7.8

  • Fix regression in restarting kernels in 5.7.5. The restart handler would return before restart was completed.
  • Further improve compatibility with tornado 6 with improved checks for when websockets are closed.
  • Fix regression in 5.7.6 on Windows where .js files could have the wrong mime-type.
  • Fix Open Redirect vulnerability (CVE-2019-10255) where certain malicious URLs could redirect from the Jupyter login page to a malicious site after a successful login. 5.7.7 contained only a partial fix for this issue.

5.7.6

5.7.6 contains a security fix for a cross-site inclusion (XSSI) vulnerability (CVE-2019–9644), where files at a known URL could be included in a page from an unauthorized website if the user is logged into a Jupyter server. The fix involves setting the X-Content-Type-Options: nosniff header, and applying CSRF checks previously on all non-GET API requests to GET requests to API endpoints and the /files/ endpoint.

The attacking page is able to access some contents of files when using Internet Explorer through script errors, but this has not been demonstrated with other browsers.

5.7.5

  • Fix compatibility with tornado 6 (4392, 4449).
  • Fix opening integer filedescriptor during startup on Python 2 (4349)
  • Fix compatibility with asynchronous KernelManager.restart_kernel methods (4412)

5.7.4

5.7.4 fixes a bug introduced in 5.7.3, in which the list_running_servers() function attempts to parse HTML files as JSON, and consequently crashes (4284).

5.7.3

5.7.3 contains one security improvement and one security fix:

  • Launch the browser with a local file which redirects to the server address including the authentication token (4260). This prevents another logged-in user from stealing the token from command line arguments and authenticating to the server. The single-use token previously used to mitigate this has been removed. Thanks to Dr. Owain Kenway for suggesting the local file approach.
  • Upgrade bootstrap to 3.4, fixing an XSS vulnerability, which has been assigned CVE-2018-14041 (4271).

5.7.2

5.7.2 contains a security fix preventing malicious directory names from being able to execute javascript. CVE request pending.

5.7.1

5.7.1 contains a security fix preventing nbconvert endpoints from executing javascript with access to the server API. CVE request pending.

5.0.0

This is the first major release of the Jupyter Notebook since version 4.0 was created by the "Big Split" of IPython and Jupyter.

We encourage users to start trying JupyterLab in preparation for a future transition.

We have merged more than 300 pull requests since 4.0. Some of the major user-facing changes are described here.

File sorting in the dashboard

Files in the dashboard may now be sorted by last modified date or name (943):

image

Cell tags

There is a new cell toolbar for adding cell tags (2048):

image

Cell tags are a lightweight way to customise the behaviour of tools working with notebooks; we're working on building support for them into tools like nbconvert and nbval. To start using tags, select Tags in the View > Cell Toolbar menu in a notebook.

The UI for editing cell tags is basic for now; we hope to improve it in future releases.

Table style

The default styling for tables in the notebook has been updated (1776).

Before:

After:

Customise keyboard shortcuts

You can now edit keyboard shortcuts for Command Mode within the UI (1347):

image

See the Help > Edit Keyboard Shortcuts menu item and follow the instructions.

Other additions

  • You can copy and paste cells between notebooks, using Ctrl-C and Ctrl-V (Cmd-C and Cmd-V on Mac).
  • It's easier to configure a password for the notebook with the new jupyter notebook password command (2007).
  • The file list can now be ordered by last modified or by name (943).
  • Markdown cells now support attachments. Simply drag and drop an image from your desktop to a markdown cell to add it. Unlike relative links that you enter manually, attachments are embedded in the notebook itself. An unreferenced attachment will be automatically scrubbed from the notebook on save (621).
  • Undoing cell deletion now supports undeleting multiple cells. Cells may not be in the same order as before their deletion, depending on the actions you did on the meantime, but this should should help reduce the impact of accidentally deleting code.
  • The file browser now has Edit and View buttons.
  • The file browser now supports moving multiple files at once (1088).
  • The Notebook will refuse to run as root unless the --allow-root flag is given (1115).
  • Keyboard shortcuts are now declarative (1234).
  • Toggling line numbers can now affect all cells (1312).
  • Add more visible Trusted and Untrusted notifications (1658).
  • The favicon (browser shortcut icon) now changes to indicate when the kernel is busy (1837).
  • Header and toolbar visibility is now persisted in nbconfig and across sessions (1769).
  • Load server extensions with ConfigManager so that merge happens recursively, unlike normal config values, to make it load more consistently with frontend extensions(2108).
  • The notebook server now supports the bundler API from the jupyter_cms incubator project (1579).
  • The notebook server now provides information about kernel activity in its kernel resource API (1827).

Remember that upgrading notebook only affects the user interface. Upgrading kernels and libraries may also provide new features, better stability and integration with the notebook interface.

4.4.0

  • Allow override of output callbacks to redirect output messages. This is used to implement the ipywidgets Output widget, for example.
  • Fix an async bug in message handling by allowing comm message handlers to return a promise which halts message processing until the promise resolves.

See the 4.4 milestone on GitHub for a complete list of issues and pull requests involved in this release.

4.3.2

4.3.2 is a patch release with a bug fix for CodeMirror and improved handling of the "editable" cell metadata field.

  • Monkey-patch for CodeMirror that resolves #2037 without breaking #1967
  • Read-only ("editable": false) cells can be executed but cannot be split, merged, or deleted

See the 4.3.2 milestone on GitHub for a complete list of issues and pull requests involved in this release.

4.3.1

4.3.1 is a patch release with a security patch, a couple bug fixes, and improvements to the newly-released token authentication.

Security fix:

  • CVE-2016-9971. Fix CSRF vulnerability, where malicious forms could create untitled files and start kernels (no remote execution or modification of existing files) for users of certain browsers (Firefox, Internet Explorer / Edge). All previous notebook releases are affected.

Bug fixes:

  • Fix carriage return handling
  • Make the font size more robust against fickle browsers
  • Ignore resize events that bubbled up and didn't come from window
  • Add Authorization to allowed CORS headers
  • Downgrade CodeMirror to 5.16 while we figure out issues in Safari

Other improvements:

  • Better docs for token-based authentication
  • Further highlight token info in log output when autogenerated

See the 4.3.1 milestone on GitHub for a complete list of issues and pull requests involved in this release.

4.3.0

4.3 is a minor release with many bug fixes and improvements. The biggest user-facing change is the addition of token authentication, which is enabled by default. A token is generated and used when your browser is opened automatically, so you shouldn't have to enter anything in the default circumstances. If you see a login page (e.g. by switching browsers, or launching on a new port with --no-browser), you get a login URL with the token from the command jupyter notebook list, which you can paste into your browser.

Highlights:

  • API for creating mime-type based renderer extensions using OutputArea.register_mime_type and Notebook.render_cell_output methods. See mimerender-cookiecutter for reference implementations and cookiecutter.
  • Enable token authentication by default. See server_security for more details.
  • Update security docs to reflect new signature system
  • Switched from term.js to xterm.js

Bug fixes:

  • Ensure variable is set if exc_info is falsey
  • Catch and log handler exceptions in events.trigger
  • Add debug log for static file paths
  • Don't check origin on token-authenticated requests
  • Remove leftover print statement
  • Fix highlighting of Python code blocks
  • json_errors should be outermost decorator on API handlers
  • Fix remove old nbserver info files
  • Fix notebook mime type on download links
  • Fix carriage symbol bahvior
  • Fix terminal styles
  • Update dead links in docs
  • If kernel is broken, start a new session
  • Include cross-origin check when allowing login URL redirects

Other improvements:

  • Allow JSON output data with mime type application/*+json
  • Allow kernelspecs to have spaces in them for backward compat
  • Allow websocket connections from scripts
  • Allow None for post_save_hook
  • Upgrade CodeMirror to 5.21
  • Upgrade xterm to 2.1.0
  • Docs for using comms
  • Set dirty flag when output arrives
  • Set ws-url data attribute when accessing a notebook terminal
  • Add base aliases for nbextensions
  • Include @ operator in CodeMirror IPython mode
  • Extend mathjax_url docstring
  • Load nbextension in predictable order
  • Improve the error messages for nbextensions
  • Include cross-origin check when allowing login URL redirects

See the 4.3 milestone on GitHub for a complete list of issues and pull requests involved in this release.

4.2.3

4.2.3 is a small bugfix release on 4.2.

Highlights:

  • Fix regression in 4.2.2 that delayed loading custom.js until after notebook_loaded and app_initialized events have fired.
  • Fix some outdated docs and links.

4.2.3 on GitHub.

4.2.2

4.2.2 is a small bugfix release on 4.2, with an important security fix. All users are strongly encouraged to upgrade to 4.2.2.

Highlights:

  • Security fix: CVE-2016-6524, where untrusted latex output could be added to the page in a way that could execute javascript.
  • Fix missing POST in OPTIONS responses.
  • Fix for downloading non-ascii filenames.
  • Avoid clobbering ssl_options, so that users can specify more detailed SSL configuration.

4.2.2 on GitHub.

4.2.1

4.2.1 is a small bugfix release on 4.2. Highlights:

  • Compatibility fixes for some versions of ipywidgets
  • Fix for ignored CSS on Windows
  • Fix specifying destination when installing nbextensions

4.2.1 on GitHub.

4.2.0

Release 4.2 adds a new API for enabling and installing extensions. Extensions can now be enabled at the system-level, rather than just per-user. An API is defined for installing directly from a Python package, as well.

./examples/Notebook/Distributing Jupyter Extensions as Python Packages

Highlighted changes:

  • Upgrade MathJax to 2.6 to fix vertical-bar appearing on some equations.
  • Restore ability for notebook directory to be root (4.1 regression)
  • Large outputs are now throttled, reducing the ability of output floods to kill the browser.
  • Fix the notebook ignoring cell executions while a kernel is starting by queueing the messages.
  • Fix handling of url prefixes (e.g. JupyterHub) in terminal and edit pages.
  • Support nested SVGs in output.

And various other fixes and improvements.

4.1.0

Bug fixes:

  • Fix cross-origin problems
  • Fix double-escaping of the base URL prefix
  • Handle invalid unicode filenames more gracefully
  • Fix ANSI color-processing
  • Send keepalive messages for web terminals
  • Fix bugs in the notebook tour

UI changes:

  • Moved the cell toolbar selector into the View menu. Added a button that triggers a "hint" animation to the main toolbar so users can find the new location. (Click here to see a screencast )
