# Run: RELEASED_CSV_VERSION=<last released csv version> CSV_VERSION=<will release csv version> make update-csv
# Example: RELEASED_CSV_VERSION=0.15.0 CSV_VERSION=0.16.0 make update-csv
# Move the olm-catalog/latest manifests to github.com/k8s-operatorhub/community-operators and open PRs to update the operator.
# https://github.com/k8s-operatorhub/community-operators/tree/main/operators/cluster-manager
# https://github.com/k8s-operatorhub/community-operators/tree/main/operators/klusterlet
# Can find the operators from https://operatorhub.io/operator/cluster-manager and https://operatorhub.io/operator/klusterlet
