None of these updates remove or downgrade python 2.7 support. This was 
discussed a bit at https://lists.debian.org/debian-python/2017/06/msg00047.html;
all the 4.x and 5.x versions still support python 2.7.

This question is definitely going to come up in the not-too-distant 
future, but for the moment only IPython (v6.1) has released a 
python3-only version, and the watch file for the existing ipython source 
package has been restricted to only fetch versions <6. My proposal (see 
the thread linked above) is to introduce a separate source package 
("ipython6"?) for this version, and build only the python2 version from 
the existing source package.

Yes, I've seen you've been doing a lot of work on the javascript side - 
thanks for your work there.

As of notebook 5.0.0, the issues are:

  * jqueryui

    notebook uses an old version (1.10) whereas debian has 1.12
    (fixed with patches, but potentially affects compatibility of
    addons). Probably wontfix unless we embed jqueryui 1.10.

  * codemirror

    debian has 5.4, notebook requires 5.22 (but nonetheless works with 5.4,
    the API appears to be sufficiently stable). I investigated updating
    this; current is 5.29, but updating to > 5.19 requires rollup + various
    plugins. Updating to 5.19 for now to get at least some of the interim
    fixes might be pragmatic.

  * preact, preact-compat, proptypes

    none of these are currently packaged, and these are typescript libs
    with a fairly extensive dependency stack. These are only used to
    implement a shortcut editor, which the current notebook package just
    disables to avoid the dependencies - but shipping a deliberately
    crippled version is not ideal, even though it's not core functionality.
