- All resources under `apps/v1beta1` and `apps/v1beta2` - use `apps/v1` instead
  - `daemonsets`, `deployments`, `replicasets` resources under `extensions/v1beta1` - use `apps/v1` instead

just the `ObjectMeta` for an object (as `PartialObjectMetadata`) are now beta as part of `meta.k8s.io/v1beta1` and configurations must be changed to use the new API.  Clients may request alternate representations of normal Kubernetes objects by passing an `Accept` header like `application/json;as=Table;g=meta.k8s.io;v=v1beta1` or `application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1`.  Older servers will ignore this representation or return an error if it is not available.  Clients may...

- Kubeadm: remove the deprecated kubeadm API `v1beta1`. Introduce a new kubeadm API `v1beta3`. See [kubeadm/v1beta3](https://pkg.go.dev/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta3) for a list of changes since `v1beta2`. Note that `v1beta2` is not yet deprecated, but will be in a future release. ([#101129](https://github.com/kubernetes/kubernetes/pull/101129), [@neolit123](https://github.com/neolit123))...

- Introduced the `admissionregistration.k8s.io/v1beta1/MutatingAdmissionPolicy` API type. To enable, enable the `MutatingAdmissionPolicy` feature gate (which was off by default) and set `--runtime-config=admissionregistration.k8s.io/v1beta1=true` on the kube-apiserver. 

API has been promoted to policy/v1 with no schema changes. The only functional change is that an empty selector (`{}`) written to a policy/v1 PodDisruptionBudget now selects all pods in the namespace. The behavior of the policy/v1beta1 API remains unchanged. The policy/v1beta1 PodDisruptionBudget API is deprecated and will no longer be served in 1.25+.
