I will paste some text below that @mlaurencin compiled in this issue #1417 which talks about whether we should use 2.0 or 2.1

However, version 3 is almost ready and the group working on it are being very intentional this time about collecting and incorporating community feedback.

The working doc:

Should we wait until this new version lands and be engaged in its development rather than figure out how to use v2.1?
