@fralken This looks great to me. You also played around with release workflows, what do you think?

[fralken]

Yes last year I made a release workflow. It is a single file using the matrix strategy.
I didn't merge it here because my idea was also to add a release for macOS but then I never found time to investigate on it.
I'm not sure if it is better to have a single workflow file dedicated to all the releases or a workflow file for each platform.

It looks good to me, too. It can be merged. Thanks a lot for this.

Anyway, I would wait creating a tag triggering the release until @gs-kamnas completes PR #97
