* The `NodeRestriction` admission plugin now prevents kubelets from modifying/removing taints applied to their Node API object. ([#63167](https://github.com/kubernetes/kubernetes/pull/63167), [@liggitt](https://github.com/liggitt))

#### Defaults

 - The default spec.updateStrategy for the StatefulSet and DaemonSet kinds is
 RollingUpdate for the apps/v1beta2 group version. You can explicitly set
 the OnDelete strategy, and no strategy auto-conversion is applied to
 replace default values.

 - As mentioned in [Behavioral Changes](#behavioral-changes), selector
 defaults are disabled.

 - The default spec.revisionHistoryLimit for all applicable kinds in the

  - `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))
