@grtyvr thanks for the fix. Can I ask you to add and fill the default PR layout on the top message?

Specifically the bullet point with ”Maintenance/Docs”. This is so you get proper credit in the automatic release notes.

The text from the PR description is not automatically used, but just meant for us maintainers so we can quickly categorize, and copy/paste more details into the release notes if needed.

By defaulty (by automation) the PR title becomes the entry in the release notes.

It does try to guess which category it is? Or is it based on labels alone?

only based on the labels
