I had to read this three times to understand what you are trying
to say, but still don't know why you picked one over the other.

The patches look fine to me overall, I only have some very minor
comments on them. The autogenerated changelogs seem actively
counterproductive though, despite your attempts to to rewrite
them into something readable. This seems to have just made the
series harder to review. Instead of telling the reader a
consistent story about what each change is for, the generated
text has too much useless detail about the implementation.
