### Bug or Regression

- Fix a bug where kube-apiserver could emit an further watch even even if decryption failed for earlier event and it was not emitted. ([#131159](https://github.com/kubernetes/kubernetes/pull/131159), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Etcd]

- kubeadm now includes the ability to specify certificate encryption and decryption keys for the upload and download certificate phases as part of the new v1beta2 kubeadm config format. ([#77012](https://github.com/kubernetes/kubernetes/pull/77012), [@rosti](https://github.com/rosti))

- Fix a bug where kube-apiserver could emit an further watch even even if decryption failed for earlier event and it was not emitted. ([#131161](https://github.com/kubernetes/kubernetes/pull/131161), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery]

- Kube-apiserver: the `--encryption-provider-config` file is now loaded with strict deserialization, which fails if the config file contains duplicate or unknown fields. This protects against accidentally running with config files that are malformed, mis-indented, or have typos in field names, and getting unexpected behavior. When `--encryption-provider-config-automatic-reload` is used, new encryption config files that contain typos after the kube-apiserver is running...

    public void setDescription_Term(String description) {

    }

- New Metrics Added for Encryption Configuration Controller
  
  This release adds new metrics to the Encryption Configuration Controller to help monitor the automatic reloading of encryption configuration. The new metrics include:
  
  - `apiserver_encryption_config_controller_automatic_reload_failures_total`: Total number of failed automatic reloads of encryption configuration.

- The API server now re-uses data encryption keys while the kms v2 plugin's key ID is stable.  Data encryption keys are still randomly generated on server start but an atomic counter is used to prevent nonce collisions.
