- This change allows the Topology, CPU, and Memory managers to recognize and act upon
  `pod.spec.resources`, enabling two flexible resource management models. Both models
  support `guaranteed` pods that contain a mix of containers that may be eligible to receive

- Pods were not allowed to mix the usage of `user-namespaces` (`hostUsers: false`) and `volumeDevices`. Kubernetes returned an error in this case. ([#132868](https://github.com/kubernetes/kubernetes/pull/132868), [@rata](https://github.com/rata))

- `etcd`: updated to `v3.5.10`. ([#121566](https://github.com/kubernetes/kubernetes/pull/121566), [@mzaian](https://github.com/mzaian))
- `k8s.io/dynamic-resource-allocation/controller:` `UnsuitableNodes` can now handle a mix of allocated and unallocated claims correctly. ([#120338](https://github.com/kubernetes/kubernetes/pull/120338), [@pohly](https://github.com/pohly))

- ValidatingAdmissionPolicy was promoted to GA and will be `enabled` by default. ([#123405](https://github.com/kubernetes/kubernetes/pull/123405), [@cici37](https://github.com/cici37))
- When scheduling a mix of pods using `ResourceClaims` and others that don't, scheduling a pod with `ResourceClaims` has a lower impact on scheduling latency. ([#121876](https://github.com/kubernetes/kubernetes/pull/121876), [@pohly](https://github.com/pohly))

## Known Issues

### CPU and Memory manager are not working correctly for Guaranteed Pods with multiple containers
