I've requested a few minor changes.

A brief note in the User Guide stating that @TempDir can be used as a meta-annotation would be helpful, perhaps even with an example.

Please also add an entry in the release notes, or if you find that too cumbersome (since the release notes file does not yet exist) just let us know, and we'll add the release note entry after merging.

Thanks for having a look.

I added something. Let me know what you think.

I copy and pasted the template. I'm not sure whether I should add "No changes" or just "*" to the sections that are empty for now.

This looks good now.

Thanks! 👍

p.s. there's a slight issue with the terminology regarding "meta-annotation" vs. "composed annotation", but I'll address that after merging the PR.
