Reason for this request

ipywidgets 8.1.5 actually is built in the anaconda channel. However, I notice that the Anaconda base distribution has downgraded to ipywidgets 7. Why? I'd like to help.

In Anaconda 2023.03, we had ipywidgets 7.6.5. Anaconda 2023.07-0 upgraded to ipywidgets 8.0.4, which persisted in Anaconda 2023.09-0.

However, Anaconda 2024.02-1, downgraded to ipywidgets 7.6.5, which was then upgraded to ipywidets 7.8.1 in Anaconda 2024.06-1. The latest documented release, Anaconda 2024.10-1, still has ipywidgets 7.8.1.

What was the reason for the downgrade back to ipywidgets 7? Can the base Anaconda ipywidgets version be upgraded to 8.1.5?

I am a former ipywidgets maintainer, and if there was a problem with using ipywidgets 8, I would like to understand and help resolve it.

Not sure who I might be able to ping about it. @danyeaw, would you know who could comment here?

Hi @jasongrout, thanks so much for reaching out. I can confirm that we do have version 8.1.5 as the latest version in the Anaconda feedstock for the package and we merged this change in December. I'm not sure why 7.x was used for the last distribution release, but the packaging team is looking in to it. Hopefully I can provide an update in a week or so.

Hi @jasongrout, I haven't forgot about this. The package build team is finalizing some testing and then I think we can confirm 100% that this will be in the next release.

[jasongrout]

Awesome, thanks for the follow up here!

Hi @jasongrout, although IPyWidgets is packaged, it looks like upgrading to version 8 in the distribution is limited by the following:

Streamlit -> pydeck -> IPyWidgets < 8

Thanks for following up here. Indeed, it looks like pydeck requires ipywidgets<8: setup.py, issue

I'll see if there's anything we can do to unblock them from upgrading.

Edit: I think it may be very easy for pydeck to support ipywidgets 7 and 8. I've posted about it here.
