5.0.0

• Files in the dashboard may now be sorted by last modified date or name (#943)
• There is a new cell toolbar for adding cell tags (#2048).
• The default styling for tables in the notebook has been updated (#1776).
• You can now edit keyboard shortcuts for Command Mode within the UI
  (#1347).

  jupyter notebook password command (#2007).

  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 (#969).

  (#1088).

  unlike normal config values, to make it load more consistently with frontend
  extensions(#2108).
• The notebook server now supports the bundler API <http://jupyter-notebook.readthedocs.io/en/latest/extending/bundler_extensions.html>__
  from the jupyter_cms incubator project <https://github.com/jupyter-incubator/contentmanagement>__ (#1579).

  its kernel resource API (#1827).
