Discrepancy between GitHub tag (v6.2.0) and npm latest version (v5.4.1)

Hi

I noticed that the latest tag in this repository is v6.2.0, but the version published on the npm registry is still v5.4.1.

Could you clarify if:

    v6.2.0 is intended to be published soon?

    Or if there’s a reason it hasn’t been released on npm yet?

This is a bit confusing when trying to ensure I'm using the latest version via npm install schwifty.

Thanks
