I recently installed AGP 3.0 and was going to set things up as I had them in my 2.9 environment. When getting to jupyterlab, and installing extensions and widgets I realized that I am still in version 2.2.10 of jupyterlab.
I hoped for an upgrade of jupyterlab from AGP 2.9 to 3.0 but it seems that did not happen. Just to be absolutely sure, is 2.2.10 still the version delivered with AGP 3.0 or did something go wrong on my side?
same here... 2.2.10
