Note for the mapping report:

While it's intended to show diffs per PR, it technically shows diffs between this PR version (which includes any previously merged PRs) and the baseline archive. Because of this some of the diffs are from a previous PR (i.e. GuideWindow fields).

@PaulHuwe this one was from #780. It's already merged, but it looks ok to me.
