This ConfigMap shares the same name as the pre-existing Secret, which is <shoot-name>.ca-cluster. The Secret will be removed in a future Gardener release. Therefore, if your tooling relies on this Secret, you should update it to fetch the ConfigMap instead. by @petersutter [#9123]

All domains are assumed to be wildcard domains. Earlier, the API only accepted one domain name via .spec.runtimeCluster.ingress.domain.
  ⚠️ With this change .spec.runtimeCluster.ingress.domain is deprecated and will be removed in the next release. Please update your Garden resource to the new .spec.runtimeCluster.ingress.domains field by removing the existing domain configuration from ingress.domain and add it as the first entry of ingress.domains. by @ScheererJ [#9038]
