An API is defined for installing directly from a Python package, as well.
.. seealso::
:doc:`./examples/Notebook/rstversions/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.
.. _release-4.1.0:

- 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 <https://cloud.githubusercontent.com/assets/335567/10711889/59665a5a-7a3e-11e5-970f-86b89592880c.gif>`__ )
.. image:: /_static/images/cell-toolbar-41.png
- 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
- Added a *Find and Replace* dialog to the *Edit* menu. Users can also press ``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.
See the 4.1 milestone on GitHub for a complete list of `issues <https://github.com/jupyter/notebook/issues?page=3&q=milestone%3A4.1+is%3Aclosed+is%3Aissue&utf8=%E2%9C%93>`__ and `pull requests <https://github.com/jupyter/notebook/pulls?q=milestone%3A4.1+is%3Aclosed+is%3Apr>`__ handled.
