Hey folks, I think it's a good time to cut v2.2.0 as it's almost a year since our last release. Was thinking I could open an issue to ask for it or make a similar one like v2.1.0 which I did here.

Here are the steps I took:

• Updated Chart.yaml/CHANGELOG.md/README.md
• Ran helm package, move the compressed chart to docs directory and ran helm repo index there
• I assume the last step would be cutting the release manually with a new tag

Other notes:

• Please feel free to close/update this PR if it's not the right release process we are doing
• Do/should we have a plan for quarterly or yearly release? Just for small patches like image tag updates

Thank You!

I think you packaged the content helm package... before updating the README.md right? I'm getting sha256sum mismatch when trying to hash my archive against yours @locmai.

Can you just rerun helm package -u . again?
