[skapin]

• Please, do intensive test !

Does it work for you? Because I get an error and the console says RemoteFrameBufferModel.__super__ is undefined

The linting job fails, because black has updated, and CI needs updating too. I'll do that in a separate PR, and we can merge main back in once that is merged.

Done. You can now merge/rebase to have a working CI and lint.

I'm waiting for a member on my team to test, i must have missed 1 or 2 things but most of the work is done :)

It's the change on super, I guess it's better now

I think it "should" works in ipywidget 7 too. I didnt have to make breaking change modification.

[skapin]

Ok i will update when it's fully working, tommorow i think

[skapin]

I confirm it's working on my side :)

I added py37. I was a bit strict letting only >=3.8 (3.7 is deprecated this summer, not yet)

FYI numpy and other scientific python libraries have dropped (or are in the process of dropping) Python 3.8.

I can confirm that it works on both the latest versions of ipywidgets / lab, as well as on the version that I last updated a year or so ago.

Older versions tests: ipywidgets : 7.6.5 jupyterlab : 3.4.7 notebook : 6.4.7

Latest versions tested: ipywidgets : 8.0.4 jupyterlab : 3.6.1 notebook : 6.5.2

@djhoese you want to have a look? Otherwise feel free to merge!

[djhoese]

No I won't have time for real testing. Let's merge and see what people think.
