- Changed underlying logic to propagate pod-level hugepage cgroup to containers when they did not specify hugepage resources.

    spec:
      podSelector:
    ```

	This will ensure that Pods that aren't matched by any other NetworkPolicy will continue to be fully-isolated, as they were in v1beta1.

	In Namespaces that previously did not have the "DefaultDeny" annotation, you should delete any existing NetworkPolicy objects. These had no effect in the v1beta1 API, but with v1 semantics they might cause some traffic to be unintentionally blocked.

would no longer crash when a DRA(Dynamic Resource Allocation) driver returns a nil as part of the Node(Un)PrepareResources response instead of an empty struct (Did not affect drivers written in Go, first showed up with a driver written in Rust). returns a nil as part of the Node(Un)PrepareResources response instead of an empty struct (did not affect drivers written in Go, first showed up with a driver written in Rust).

* StatefulSet: The deprecated `pod.alpha.kubernetes.io/initialized` annotation for interrupting the StatefulSet Pod management is now ignored. StatefulSets with this annotation set to `true` or with no value will behave just as they did in previous versions. Dormant StatefulSets with the annotation set to `false` will become active after upgrading.

- Fixes a regression introduced in 1.29 where conntrack entries for UDP connections
  to deleted pods did not get cleaned up correctly, which could (among other things)
  cause DNS problems when DNS pods were restarted. ([#127808](https://github.com/kubernetes/kubernetes/pull/127808), [@danwinship](https://github.com/danwinship)) [SIG Network]

* The namespace API object no longer supports the deletecollection operation, which was previously allowed by mistake and did not respect expected namespace lifecycle semantics. ([#47098](https://github.com/kubernetes/kubernetes/pull/47098), [@liggitt](https://github.com/liggitt))
