Hi, The optional package Jupyterlab has been upgraded to version 3.3.1 in https://trac.sagemath.org/ticket/32069 (merged in Sage 9.6.beta5)
Jupyterlab offers more functionalities than the classic Jupyter Notebook and is aimed to replace it, see e.g. https://jupyterlab.readthedocs.io/en/stable/getting_started/overview.html Maybe it is time to make it a standard package in Sage. To be clear, this is not to switch (yet) the default notebook interface from the classic Jupyter Notebook to Jupyterlab, but simply to make the following commands work out of the box: (1) sage -n (2) sage -n jupyterlab with (1) launching the classic Jupyter Notebook (current behavior). At the moment, (2) fails by complaining that Jupyterlab is not installed. In a second stage, we could get rid of the Jupyter Notebook as a standard package, but still keeping the same user interface as (1) and (2) thanks to the extension nbclassic of Jupyterlab. This extension has been added to #32069. Then (1) will run Jupyterlab with the nbclassic interface, which is identical to the classic Jupyter Notebook one. In a third stage, we could make Jupyterlab the default by having (1) running it and having the old interface still accessible via (3) sage -n nbclassic Please vote.
