### **Apps**

*   The `kubernetes.io/created-by` annotation is no longer added to controller-created objects. Use the `metadata.ownerReferences` item with controller set to `true` to determine which controller, if any, owns an object. ([#54445](https://github.com/kubernetes/kubernetes/pull/54445),[ @crimsonfaith91](https://github.com/crimsonfaith91))

    * In order to remain backwards compatible, the new controller only manages attach/detach of volumes that are scheduled to nodes that opt-in to controller management. Nodes running v1.3 or higher of Kubernetes opt-in to controller management by default by setting the "volumes.kubernetes.io/controll...

For detailed release notes on the three alpha features from SIG AWS, please refer to the following Changelogs:

- [aws-alb-ingress-controller v1.0.0](https://github.com/kubernetes-sigs/aws-alb-ingress-controller/releases/tag/v1.0.0)
- [aws-ebs-csi-driver v0.1](https://github.com/kubernetes-sigs/aws-ebs-csi-driver/releases/tag/v0.1.0)

#### Network
- EndpointSlices: If upgrading a cluster with EndpointSlices already enabled, any EndpointSlices that should be managed by the EndpointSlice controller should have a `endpointslice.kubernetes.io/managed-by` label set to `endpointslice-controller.k8s.io`.

- Defining minimum required documentation from each cloud provider which includes (in collaboration with SIG Docs):
  - example manifests for the kube-apiserver, kube-controller-manager, kube-schedule, kubelet, and the cloud-controller-manager
  - labels/annotations that are consumed by any cloud specific controllers

In addition to the above, SIG Cloud Provider has been focusing on a long running effort to remove cloud provider code from kubernetes/kubernetes.

- `kube-controller-manager` and `cloud-controller-manager` have changed the
  name of controllers that can be turned on/off that are passed to the `--controllers`
  flag (e.g., `pod-garbage-collector-controller`). The old names (eg `podgc`) are

- The following roles have had `Watch` added to them (prefixed with `system:controller:`):
  
  - `cronjob-controller`
  - `endpoint-controller`
  - `endpointslice-controller`
  - `endpointslicemirroring-controller`
  - `horizontal-pod-autoscaler`
  - `node-controller`
  - `pod-garbage-collector`
