- 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`). ([#114523](https://github.com/kubernetes/kubernetes/pull/114523), [@zshihang](https://github.com/zshihang)) [SIG API Machinery and Auth]

The Service Plan Defaults feature is still under active development.
We continue to improve the UX for the svcat CLI, specifically filling in gaps for the new Namespaced Service Broker feature.

## 0.83.0

🚨 This is probably the last release (or one of the last releases) to support Python 3.6. 🔥

Python 3.6 reached the [end-of-life and is no longer supported by Python](https://www.python.org/downloads/release/python-3615/) since around a year ago.

* vSphere kube-up: Wait for cbr0 configuration to complete before setting up routes. ([#35232](https://github.com/kubernetes/kubernetes/pull/35232), [@kerneltime](https://github.com/kerneltime))
* Remove last probe time from replica sets ([#35199](https://github.com/kubernetes/kubernetes/pull/35199), [@kargakis](https://github.com/kargakis))

- Kube-apiserver reported the last configuration hash as a label in
  
  - `apiserver_authentication_config_controller_last_config_info` metric after successfully loading the authentication configuration file.

  - `GCERegionalPersistentDisk`

## Metrics Changes

### Added metrics

- The metric `kube_proxy_sync_proxy_rules_last_timestamp_seconds` is now available, indicating the last time that kube-proxy successfully applied proxying rules. ([#74027](https://github.com/kubernetes/kubernetes/pull/74027), [@squeed](https://github.com/squeed))

* Fixes an issue where the resourceVersion of an object in a DELETE watch event was not the resourceVersion of the delete itself, but of the last update to the object. This could disrupt the ability of clients clients to re-establish watches properly. ([#58547](https://github.com/kubernetes/kubernetes/pull/58547), [@liggitt](https://github.com/liggitt))
