A developer has submitted a PR on Github to update the Helm provider to use Helm version 3. That version of helm has been released, and many teams are moving to it. Since it does not run a Tiller server in the cluster, but talks directly to the Kubernetes Controller API, it is fundamentally incompatible.
I am hoping a maintainer can get involved and see this to release. Building and distributing it ourselves among our engineering team is not how I want to proceed with this.
