Add JupyterLab link to README

[mgeier]

BTW, is this "roadmap" project still used? It seems a bit outdated ...

I actually wanted to find this information:

Is it already decided whether JupyterLab will replace the Notebook?
If not, when will it be decided?

Will there be a feature freeze (or something similar) of the Notebook in order to concentrate work on JupyterLab?

Yeah we are a bit overwhelmed and are in the process of cleaning up a bit of that behind the scene.

Yes it will, when is not exactly decided yet, we still need to do at least 3 phases:

• notebook comes by default, JupyterLab as a plugin
• both comme by default.
• Lab by default, notebook as a plugin.
• (Notebook not maintained?)

So it will take a few years. This will probably interleave with stopping support for Python 2 for the notebook server.

Yes-ish, the amount of work on the notebook has still decreased quite a bit, and should decrease more once JupyterLab adoption is higher.
