Changelog looks good. Let's wait on those last few PRs before we cut this though.

the url_master parameter of HLSStream and MuxedHLSStream was deprecated in favor of multivariant, ...

I don't think a deprecation notice is needed. We're really just matching newer standards.

@bastimeyer I think everything that needs to get in should be in, the vimeo update would be nice to have but I don't think that's ready. Anything else you want to get in before I merge this and cut the release?

Given that the Vimeo issue has been open for a year and half, it probably doesn't matter if it doesn't go into this release, although as you say, it would be nice.

The other thing about that PR is not only the Vimeo plugin itself, but whether or not the changes in stream.hls that are required for the Vimeo plugin fix are fully decided upon also.

I will try and get back to it shortly in any case.

@mkbloke Definitely not a big deal so don't inconvenience yourself, it's just the only PR currently open that will be merged at some point.

#4643 should be merged before 4.2.0 gets released.

@bastimeyer #4643 is in.

Why was the "New release" step skipped?
https://github.com/streamlink/streamlink/runs/7260805016

That's the run condition:

The only recent change was this, but that shouldn't be relevant, as the workflow was already triggered:

Ok, none of the action workflow runs was triggered by the tag-push.
https://github.com/streamlink/streamlink/actions

Tag 4.2.0 exists though:
https://github.com/streamlink/streamlink/releases/tag/4.2.0

Why is it saying that I tagged it? I didn't...

Since I don't know what you did and what happened exactly, @gravyboat, I will delete the tag now and push a new one.

So apparently, the branches-ignore list is responsible for this:
https://docs.github.com/en/actions/using-workflows/triggering-a-workflow#using-filters-to-target-specific-branches-or-tags-for-push-events

If you define only tags/tags-ignore or only branches/branches-ignore, the workflow won't run for events affecting the undefined Git ref. If you define neither tags/tags-ignore or branches/branches-ignore, the workflow will run for events affecting either branches or tags.

@bastimeyer For future reference when I tag all I do is pull the latest down, git tag x.x.xx then git push origin x.x.xx. Nothing fancy.
