This is still a completely inadequate changelog. I really will not
accept patches like this.

Hi,

The changelog is added in the cover-letter ("[PATCH v3 0/5] perf report: Show branch type").

Does the changelog need to be added in each patch's description?

That's fine, I can add and resend this patch.

The cover letter is not retained; it is throw away information.

Each patch should have a coherent changelog that explain why the patch
was done and explain non trivial things in the implementation.

Simply copy/pasting the same story in multiple patches is not right
either, for the simple fact that the patches were not the same. You did
a different thing, so you need a different story.
