Good question. I'm not sure.
@maelle Sorry to bother you. But, is there any way to preview pkgdown website built in the PR?

does this override the automatic versioning inferred from NEWS.md?

No, it won't. The NEWS menu should look something like this (of course, there will just be a single entry for 3.0.0 release) after the PR is merged.

• you could do like pkgdown's own repo https://github.com/r-lib/pkgdown/blob/main/.github/workflows/pkgdown.yaml#L59= using Netlify, or https://developers.cloudflare.com/pages/platform/preview-deployments/ that I was recently told about
• in cynkra/fledge if a branch name starts with docs it's deployed to the development website if I'm not mistaken see https://github.com/cynkra/fledge/blob/main/.github/workflows/pkgdown.yaml
