@OlafMerkert want to sign the CLA ? 🙏

I already signed the CLA, the Quality gate for that passes. I suppose it needs to be reviewed and approved by a maintainer?

[adidahiya]

@b-fett I'll make a release this week... note that in the meantime, you can install an NPM package from a git branch (like this repo's master branch)... https://medium.com/@jonchurch/use-github-branch-as-dependency-in-package-json-5eb609c81f1a

@adidahiya thanks for response.

Unfortunately this post is not relevant. Since library written in Typescript, it needs to be compiled before use, not just add to package.

@b-fett just released 4.1.0, please try it out
