- The AnyVolumeDataSource feature is now beta, and the feature gate is enabled by default. In order to provide user feedback on PVCs with data sources, deployers must install the VolumePopulators CRD and the data-source-validator controller.

#### Node Authorization

### Etcd v3.5.[0-2] data corruption

Data corruption issue was found in etcd v3.5.0 release that was shipped with 1.22 Kubernetes release. Please read up-to-date [production recommendations for etcd](https://github.com/etcd-io/etcd/tree/main/CHANGELOG).

## Urgent Upgrade Notes 

- We will no longer automatically delete all data when a failure is detected during creation of the volume data file on a CSI volume. Now we will only remove the data file and volume path. ([#96021](https://github.com/kubernetes/kubernetes/pull/96021), [@huffmanca](https://github.com/huffmanca)) [SIG Storage]

## Dependencies

  - NetworkPolicy resources will no longer be served from `extensions/v1beta1` in v1.16. Migrate use to the `networking.k8s.io/v1` API, available since v1.8. Existing persisted data can be retrieved via the `networking.k8s.io/v1` API.

- New configuration is introduced to the kubelet that allows it to track container images and the list of authentication information that leads to their successful pulls. This data is persisted across reboots of the host and restarts of the kubelet.
