thanks for the PR, mind adding a test for this new feature?

[lholmquist]

no need for this in the PR, we have some automation that will update the version when we do the release

[contactjittu]

removed version bump

[lholmquist]

looks like the tests are fine, but it's failing on uploading codecoverage. I fixed that in this issue #381 , would you mind doing a quick rebase?

[lholmquist]

Looks good. Thanks for the PR
