@SylvainCorlay - did you want to look into that queued execution thing that you say is causing problems with nbextensions? I'm happy to sit down with you and try to think it through - I'm still don't quite understand how those are conflicting.

I have been trying to reproduce it with notebook 5 and could not trigger the faulty behavior. I would be happy to discuss this tomorrow.

Thanks @ellisonbg for opening this. This would be super helpful to go ahead with the ipywidgets release.

Ok, does everyone agree that we should push 4.4 out today with just #2022?

[ellisonbg]

We should confirm with @minrk @takluyver first as they have been doing lots of the work for 5.0. But I am +1

[minrk]

I'm fine with 4.4 with just this. Since 4.3 introduced the token stuff, it could be logical to include jupyter notebook password in the backport, since it is related to making notebook auth easier. But since 5.0 is quite soon as well, I don't think it needs a backport.

[ellisonbg]

I am fine either way with the jupyter notebook password. If it is easy and quick to backport sounds good, otherwise, no worry.

I just UX tested Widget List.ipynb and everything appears to be working properly

OK (SKIP=1)

None of these seem related to #2022, but please chime in if anything looks suspicious. I will run Travis against 4.x branch before releasing.

It's a relatively easy backport. There are docs that specifically reference 'new in 5.0' that would need to be updated, though, so it might not be worth the bother.
