I would have the feature requests for being able to add multiple changelog segments in one PR, segments that end up in the same section of the changelog.

I think it's beneficial in many cases to have multiple entries rather than one long paragraph for new feature additions, but for maintenance supporting this would be crucial. E.g. in a project, I'm dropping support for multiple dependency versions. All of those need their clean, short changelog entry and currently, I am bound to open separate PRs for this to be able to handle the changelog, even though logically and logistically it would be much nicer to do it in one go.
