FY #13242 is listed twice (looks like a pure duplicate rather than an accidental replacement of something else, based on the commits)

[mattpap]

It was a duplicate, due to me fighting with github's primitive UI.

[mattpap]

@bokeh/dev, this is ready. When approved, I will start 3.2.1 release build.

It looks like this includes some of the regression tests added in #13195 but we don't have the new functionality of that PR so the tests fail. That PR is probably too significant to add in here, so maybe we should just remove the regression tests?

[bryevdv]

When approved, I will start 3.2.1 release build.

You'll want update switcher.json with the new version first

You'll want update switcher.json with the new version first

OK. Shouldn't this be done automatically by the release build? Actually, I don't see it being updated in the preview backports PR (#13103).

[mattpap]

(...), so maybe we should just remove the regression tests?

Yes. That was a bad cherry-pick with conflicts.

[mattpap]

I see switcher.json was updated in a follow-up commit in 3.1.1. This also reminds me about release notes.

[bryevdv]

Shouldn't this be done automatically by the release build?

It would be nice for this to be done automatically, yes.

I don't see it being updated in the preview backports PR

Sometimes it happens in a separate docs/release notes PR
