Duplicate subsection headings in 3.8.rst porting section?

I was looking to edit the documentation here : https://docs.python.org/3.8/whatsnew/3.8.html in relation to a recent PR I am working on and found something odd.

In the porting section there are two subsections named " Changes in the C API" . I think written by different authors. This prompted me to ask before I made any edits. Before I could dismiss this as an error, I thought what If it was intended? I have seen that other entries are grouped together under common headings except this one.

@methane and @eelizondo is this an error or was it intended ?

Probably the first two PRs were in the pipeline at the same time. If you are making a PR already, feel free to delete the duplicate heading. Otherwise, it should eventually get caught.
