- Kubelet/stats: set INFO log level for stats not found in cadvisor memory cache error. ([#125656](https://github.com/kubernetes/kubernetes/pull/125656), [@gyuho](https://github.com/gyuho))
- Kubelet: warn instead of error for the unsupported options on Windows "CgroupsPerQOS" and "EnforceNodeAllocatable". ([#123137](https://github.com/kubernetes/kubernetes/pull/123137), [@neolit123](https://github.com/neolit123)) [SIG Node and Windows]

- Creation of new `CronJob` objects containing `TZ` or `CRON_TZ` in `.spec.schedule`, accidentally enabled in `v1.22`, is now disallowed. Use the `.spec.timeZone` field instead, supported in `v1.25+` clusters in default configurations. See https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#unsupported-timezone-specification for more information. ([#116252](https://github.com/kubernetes/kubernetes/pull/116252), [@soltysh](https://github.com/soltysh))

- Runtime handler and Windows npipe protocol are not supported yet in crictl v1.11.x. Those features will be supported in crictl [v1.12.0](https://github.com/kubernetes-sigs/cri-tools/releases/tag/v1.12.0), together with Kubernetes v1.12.1.

## Major Themes

### SIG API Machinery

Dynamic Resource Allocation (DRA) got promoted to beta. No action is required when *upgrading*, the previous v1alpha3 API is still supported, so existing deployments and DRA drivers based on v1alpha3 continue to work. *Downgrading* from 1.32 to 1.31 with DRA resources in the cluster (resourceclaims, resourceclaimtemplates, deviceclasses, resourceslices) is *not* supported because the new v1beta1 is used as storage version and not readable by 1.31. ([#127511](https://github.com/kubernetes/kubernetes/pull/127511),...

- When an unsupported PodDisruptionBudget configuration is found, an event and log will be emitted to inform users of the misconfiguration. ([#115861](https://github.com/kubernetes/kubernetes/pull/115861), [@JayKayy](https://github.com/JayKayy)) [SIG Apps]

All StorageClass parameters for volume provisioning and all features supported with PersistentVolumeClaims are supported.

### Skip Volume Ownership change graduates to GA

The feature to configure volume permission and ownership change policy for Pods moved to GA in 1.23.

- Kubeadm: updated the supported etcd version to v3.5.23 for supported control plane versions v1.31, v1.32, and v1.33. ([#134692](https://github.com/kubernetes/kubernetes/pull/134692), [@joshjms](https://github.com/joshjms)) [SIG Cluster Lifecycle and Etcd]

- As of v1.25, the PodSecurity `restricted` level no longer requires pods that set .spec.os.name="windows" to also set Linux-specific securityContext fields. If a 1.25+ cluster has unsupported [out-of-skew](https://kubernetes.io/releases/version-skew-policy/#kubelet) nodes prior to v1.23 and wants to ensure namespaces enforcing the `restricted` policy continue to require Linux-specific securityContext fields on all pods, ensure a version...

        *   HostPorts are not supported.
*   An IPv6 network mask for pod or cluster cidr network must be /66 or longer. For example: 2001:db1::/66, 2001:dead:beef::/76, 2001:cafe::/118 are supported. 2001:db1::/64 is not supported
