* kube-apiserver --advertise-address is now set using downward API for self-hosted Kubernetes with kubeadm. ([#56084](https://github.com/kubernetes/kubernetes/pull/56084), [@andrewsykim](https://github.com/andrewsykim))

* Features:

  * Add Host field to TCPSocketAction ([#42902](https://github.com/kubernetes/kubernetes/pull/42902), [@louyihua](https://github.com/louyihua))

	* Add the ability to lock on ConfigMaps to support HA for self hosted components ([#42666](https://github.com/kubernetes/kubernetes/pull/42666), [@timothysc](https://github.com/timothysc))

### Cluster Lifecycle

#### kubeadm

* [beta] A new `upgrade` subcommand allows you to automatically upgrade a self-hosted cluster created with kubeadm. ([#296](https://github.com/kubernetes/enhancements/issues/296), [@luxas](https://github.com/luxas))

* Fix erroneous FailedSync and FailedMount events being periodically and indefinitely posted on Pods after kubelet is restarted ([#44781](https://github.com/kubernetes/kubernetes/pull/44781), [@wongma7](https://github.com/wongma7))

* Self hosted is no longer supported in the standard workflow. The feature flags have been removed and your self hosted cluster is no longer able to upgrade via kubeadm. ([#69878](https://github.com/kubernetes/kubernetes/pull/69878), [@Klaven](https://github.com/Klaven))

#### **Cloud Provider Integration**

- Structured Authentication Configuration now supports `DiscoveryURL`. If specified, `discoveryURL` overrides the URL used to fetch discovery information. This is for scenarios where the well-known and jwks endpoints are hosted at a different location than the issuer (such as locally in the cluster).
