Not sure where to ask, but I see that the chart version is of 3.0.1 on master, but that version have not been released.
When/What triggers a release of the charts?

I'm fairly new to contributing to an open source project. What is the normal lead time to get a pull request through?
To me it seems like a very slow pace at the moment (this simple pull request have activity from 1/3 maintainers) and that will get potential consumer to hesitate to use the tool.
