@woile @Lee-W @noirbizarre Please check this Pull Request,

I think it would be good if this repo also had a CODEOWNERS file. Otherwise, it's not clear who checks the pull requests.

Sorry if I'm annoying you :)

I'll take a look later this week

[Lee-W]

overall, it looks good. not sure what fails the CI. might need to take a look

[ckagerer]

I think the CI is failing because there are no tags in the fork “No tag found to do an incremental changelog”. I have created a tag for the latest version. Hope it works.

hmmm... not sure why folk will affect the CI on our end, but looks good to me. Will keep it open for one or two days so @woile and @noirbizarre can take a look

After I tagged the last release in my fork, it went through.
The problem is that the action simulates the next release. But when you create a fork at GitHub, which I need to submit the PR, existing tags are apparently not copied. The action clones my fork because it contains my feature branch. That's why the pipeline breaks off because the tag of the last release is missing.

All right. And thanks for the review.

Thanks so much for helping us investigate it. I was to do it but not yet have the bandwidth

, existing tags are apparently not copied.

Sounds like something we need to fix. But I'll merge this now and probably get back to this later. Thanks!
