What is the right approach for updating the command line tools reference? Manually edit the HTML table?

That needs to be part of this PR.

We typically update all generated docs during the release, separately from human-made PRs that accompany changes in that release.

If that's true here to, we can /unhold.

Sounds like I don't need to worry about the reference docs then.

We need to check that this complex table is rendered correctly. It works in GitHub, but I am not sure about the Kubernetes HTML.

Where can I find the preview pages?

Hmm, "Deploy preview" is just plain text when I look at that comment.

I see a link to the deploy log, but that also doesn't link to the preview.

Ah sorry. It turns out that as a privileged user I get that link and other folks don't.
Not sure why (I don't see it as confidential and the URLs are predictable).

I might nudge Netlify about that if I get time. It's a busy period though!
