Now that we have a new release waiting, we would go through the same process as before. Someone would make a decision whether the release should be deployed to production or to let it rot until the new one comes along. If the decision is made that our users should benefit from the features available in that release, we'd need to update a few files in our k8s-prod repository.

 1  cd ../k8s-prod

The first file we'll update is helm/requirements.yaml. Please open it in your favorite editor and change the go-demo-5 version to match the version of the Chart we pushed a few moments ago.
