@jutzig would very much appreciate a review. Thank you.

hi @jutzig , would be great to hear your feedback on this one.

Hi @anenviousguest Thanks again for another pull request, that sounds like a great idea. TBH, I didn't even know that github does automatic release note generation like that. I assume following this, one can customize the default output? https://docs.github.com/en/repositories/releasing-projects-on-github/automatically-generated-release-notes

What do you think about adding the first picture from your pull request as an example to the readme and include the link to automatic release notes description? I don't want to use the picture without permission, since it includes your user handle...

I guess so, at least on the API page they do mention that YAML file.

No prob at all, let me update the README then...

Hi @jutzig , I updated the README with your link and put a screenshot there as well.
