LGTM! I've encountered this kind of problem several times in the past, and it seems to be caused by conflicts in the changelog file.

Yeah, I noticed. I think it's going to be recurrent for components & dataviews (packages for which every PR is added to the changelog) when we release new packages, as that creates newer sections in the changelog file. :/
