- `apiserver_encryption_config_controller_automatic_reload_success_total`: Total number of successful automatic reloads of encryption configuration.
  - `apiserver_encryption_config_controller_automatic_reload_last_timestamp_seconds`: Timestamp of the last successful or failed automatic reload of encryption configuration.
  

- Clean ReplicaSet by revision instead of creation timestamp in deployment controller ([#97407](https://github.com/kubernetes/kubernetes/pull/97407), [@waynepeking348](https://github.com/waynepeking348)) [SIG Apps]

* Upgrade Stackdriver Logging Agent addon image to 0.6-1.6.0-1 to use Fluentd v1.2. This provides nanoseconds timestamp granularity for logs. ([#70954](https://github.com/kubernetes/kubernetes/pull/70954), [@qingling128](https://github.com/qingling128))

- Graduated the `LegacyServiceAccountTokenTracking` feature gate to Beta. The usage of auto-generated secret-based service account token now produces warnings by default, and relevant Secrets are labeled with a last-used timestamp (label key `kubernetes.io/legacy-token-last-used`).

- Fix network_programming_latency metric reporting for Endpoints/EndpointSlice deletions, where we don't have correct timestamp ([#95363](https://github.com/kubernetes/kubernetes/pull/95363), [@wojtek-t](https://github.com/wojtek-t)) [SIG Network and Scalability]

* Moved qos to api.helpers. ([#44906](https://github.com/kubernetes/kubernetes/pull/44906), [@k82cn](https://github.com/k82cn))
* Kubelet PLEG updates the relist timestamp only after successfully relisting. ([#45496](https://github.com/kubernetes/kubernetes/pull/45496), [@andyxning](https://github.com/andyxning))

- kube-apiserver now reloads the `--authorization-config` file when it changes. Reloads increment the `apiserver_authorization_config_controller_automatic_reload_last_timestamp_seconds` timestamp metric, with `status="success"` for successful reloads and `status="failed"` for failed reloads. Failed reloads keep using the previously loaded authorization configuration.

  `terminating` is true when an endpoint is terminating. For pods this is any endpoint with a deletion timestamp. ([#92968](https://github.com/kubernetes/kubernetes/pull/92968), [@andrewsykim](https://github.com/andrewsykim)) [SIG Apps and Network]
- Add dual-stack Services (alpha).  This is a BREAKING CHANGE to an alpha API.
