 the apps/v1beta1 API in this release, but you should start planning for code
 that does not depend on mutable selectors.

 - Extended Resources are fully-qualified resource names outside the
 `kubernetes.io` domain. Extended Resource quantities must be integers.
 You can specify any resource name of the form `[aaa.]my-domain.bbb/ccc`

* Check if container memory stats are available before accessing it ([#77656](https://github.com/kubernetes/kubernetes/pull/77656), [@yastij](https://github.com/yastij))
* Fixes segmentation fault issue with Protobuf library when log entries are deeply nested. ([#77224](https://github.com/kubernetes/kubernetes/pull/77224), [@qingling128](https://github.com/qingling128))

- Fix performance issue when creating large objects using SSA with fully unspecified schemas (preserveUnknownFields).

- Finalizer Protection for Service LoadBalancers is now in GA (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted. ([#85023](https://github.com/kubernetes/kubernetes/pull/85023), [@MrHohn](https://github.com/MrHohn))

- The v1 Endpoints API is now officially deprecated (though still fully supported). The API will not be removed, but all users should use the EndpointSlice API instead. ([#130098](https://github.com/kubernetes/kubernetes/pull/130098), [@danwinship](https://github.com/danwinship)) [SIG API Machinery and Network]

- Reverted the previous fix for portforward cleanup because it introduced a kubelet regression which can lead into segmentation faults. ([#102587](https://github.com/kubernetes/kubernetes/pull/102587), [@saschagrunert](https://github.com/saschagrunert)) [SIG API Machinery and Node]

### Other (Cleanup or Flake)

- Finalizer Protection for Service LoadBalancers is now in beta (enabled by default). This feature ensures the Service resource is not fully deleted until the correlating load balancer resources are deleted.
