Jupyter notebook changelog
==========================
A summary of changes in the Jupyter notebook.
For more detailed information, see
`GitHub <https://github.com/jupyter/notebook>`__.
.. tip::
Use ``pip install notebook --upgrade`` or ``conda upgrade notebook`` to
upgrade to the latest release.
.. we push for pip 9+ or it will break for Python 2 users when IPython 6 get out.
Upgrade to version 9+ of pip before upgrading ``notebook`` is strongly recommended.
.. tip::
Use ``pip install pip --upgrade`` to upgrade pip. Check pip version with
``pip --version``.
.. _release-5.0.0:
Notebook version 5.0
--------------------
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 200 pull requests since the 4.x series. Some of the
major user-facing changes are described here.
Cell tags
*********
There is a new cell toolbar for adding *cell tags* (:ghpull:`2048`):
.. image:: /_static/images/cell-tags-toolbar.png
:align: center
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
<http://nbconvert.readthedocs.io/en/latest/>`__ and `nbval
<https://github.com/computationalmodelling/nbval>`__.
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 (:ghpull:`1776`):
.. image:: /_static/images/table-style-change.png
:align: center
Customise keyboard shortcuts
****************************
You can now edit keyboard shortcuts for command mode within the UI
(:ghpull:`1347`):
.. image:: /_static/images/shortcut-editor.png
:align: center
See the ``Help > Edit Keyboard Shortcuts`` menu item and follow the instructions.
Other additions
***************
- You can copy and paste cells between notebooks, using :kbd:`Ctrl-C` and
:kbd:`Ctrl-V` (:kbd:`Cmd-C` and :kbd:`Cmd-V` on Mac).
- It's easier to configure a password for the notebook with the new
``jupyter notebook password`` command (:ghpull:`2007`).
- The file list can now be ordered by *last modified* or by *name*
(:ghpull:`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 (:ghpull:`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
(:ghpull:`1088`).
- The Notebook will refuse to run as root unless the ``--allow-root`` flag is
given (:ghpull:`1115`).
- Keyboard shortcuts are now declarative (:ghpull:`1234`).
- Toggling line numbers can now affect all cells (:ghpull:`1312`).
- Add more visible *Trusted* and *Untrusted* notifications (:ghpull:`1658`).
- The tab icon in the browser now changes to indicate when the kernel is busy
(:ghpull:`1837`).
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.
.. _release-4.4.0:
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 <https://github.com/jupyter/notebook/issues?utf8=%E2%9C%93&q=is%3Aissue%20milestone%3A4.4>`__
and `pull requests <https://github.com/jupyter/notebook/pulls?utf8=%E2%9C%93&q=is%3Apr%20milestone%3A4.4>`__ involved in this release.
.. _release-4.3.2:
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 <https://github.com/jupyter/notebook/issues/2037>`__ without breaking `#1967 <https://github.com/jupyter/notebook/issues/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 <https://github.com/jupyter/notebook/issues?utf8=%E2%9C%93&q=is%3Aissue%20milestone%3A4.3.2>`__
and `pull requests <https://github.com/jupyter/notebook/pulls?utf8=%E2%9C%93&q=is%3Apr%20milestone%3A4.3.2>`__ involved in this release.
.. _release-4.3.1:
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 <https://github.com/jupyter/notebook/issues?utf8=%E2%9C%93&q=is%3Aissue%20milestone%3A4.3.1>`__
and `pull requests <https://github.com/jupyter/notebook/pulls?utf8=%E2%9C%93&q=is%3Apr%20milestone%3A4.3.1>`__ involved in this release.
.. _release-4.3:
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 :code:`OutputArea.register_mime_type` and :code:`Notebook.render_cell_output` methods. See `mimerender-cookiecutter <https://github.com/jupyterlab/mimerender-cookiecutter>`__ for reference implementations and cookiecutter.
- Enable token authentication by default. See :ref:`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 :code:`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
- :code:`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 :code:`None` for post_save_hook
- Upgrade CodeMirror to 5.21
- Upgrade xterm to 2.1.0
- Docs for using comms
- Set :code:`dirty` flag when output arrives
- Set :code:`ws-url` data attribute when accessing a notebook terminal
- Add base aliases for nbextensions
- Include :code:`@` 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

- Added *Restart & Run All* to the *Kernel* menu. Users can also bind it to a
keyboard shortcut on action ``restart-kernel-and-run-all-cells``.
- Added multiple-cell selection. Users press ``Shift-Up/Down`` or ``Shift-K/J``
to extend selection in command mode. Various actions such as cut/copy/paste,
execute, and cell type conversions apply to all selected cells.
.. image:: /_static/images/multi-select-41.png
- Added a command palette for executing Jupyter actions by name. Users press
``Cmd/Ctrl-Shift-P`` or click the new command palette icon on the toolbar.
.. image:: /_static/images/command-palette-41.png

``F`` in command mode to show the dialog.
.. image:: /_static/images/find-replace-41.png
Other improvements:
- Custom KernelManager methods can be Tornado coroutines, allowing async
operations.
- Make clearing output optional when rewriting input with
``set_next_input(replace=True)``.
- Added support for TLS client authentication via ``--NotebookApp.client-ca``.
- Added tags to ``jupyter/notebook`` releases on DockerHub. ``latest``
continues to track the master branch.
