Upgrading from v1.6 to v1.7

⚠ Following their deprecation in version 1.5, the cert-manager API versions v1alpha2, v1alpha3, and v1beta1 have been removed. You must ensure that all cert-manager custom resources are stored in etcd at version v1 and that all cert-manager CustomResourceDefinitions have only v1 as the stored version before upgrading. Please read Migrating Deprecated API Resources for full instructions.

If you are currently using HTTP-01 challenges or the Ingress shim annotations, please read the Ingress class compatibility notes to see if your Ingress controller has any known issues with the migration to Ingress v1.

If running Kubernetes versions before v1.22, the ServerSideApply feature gate must be enabled in the cluster. This beta feature is enabled by default on supported versions before v1.22.
