.. _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`):

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`).

4.4.0
-----

- The tab icon in the browser now changes to indicate when the kernel is busy
(:ghpull:`1837`).
- Allow override of output callbacks to redirect output messages
- 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.

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.
