.. - 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`).
