+      (go/v2, go/v3, ansible/v1, helm/v1) Fixed the Prometheus `ServiceMonitor` metrics endpoint,
+      which was not configured to be scraped correctly.
+    kind: bugfix
+    migration:
+      header: (go/v2, go/v3, ansible/v1, helm/v1) Add scheme, token, and TLS config to the Prometheus `ServiceMonitor` metrics endpoint.
+      body: >
+        The `/metrics` endpoint, while specifying the `https` port on the manager Pod, was not actually configured
+        to serve over https because no tlsConfig was set. Since kube-rbac-proxy secures this endpoint as a
+        manager sidecar, using the service account token mounted into the Pod by default corrects this problem.
+
+        The changes should look like:
+
+        ```diff
+        # config/prometheus/monitor.yaml
+
+        spec:
+           endpoints:
+             - path: /metrics
+               port: https
+        +      scheme: https
+        +      bearerTokenFile: /var/run/secrets/kubernetes.io/serviceaccount/token
+        +      tlsConfig:
+        +        insecureSkipVerify: true
+           selector:
+             matchLabels:
+               control-plane: controller-manager
+        ```
+
+        **Note:** if you have removed kube-rbac-proxy from your project, make sure to secure the `/metrics`
+        endpoint using a proper [TLS configuration](https://prometheus.io/docs/guides/tls-encryption/).
