@xjm, thanks for making this issue.

I left some suggestions on the doc. I do prefer this overview to have a image with generic version numbers (x.0.0) and date (Y1, Y2) to make it obvious that it is an example. But none of those are blocking this from being posted. And work is been done over in 📌 Template for Core release cycles diagram RTBC that should help with maintaining these images.

Leaving at RTBC.

Oh, I checked that all the links are correct.

Worked on this more on a second sponsor's time, so updating attribution accordingly.

This documentation update is now published.
