- Kubeadm: ensured waiting for apiserver uses a local client that doesn't reach to the control plane endpoint and instead reaches directly to the local API server endpoint. ([#134269](https://github.com/kubernetes/kubernetes/pull/134269), [@neolit123](https://github.com/neolit123))...

- Enabled kube-controller-manager '--concurrent-job-syncs' flag works on orphan Pod processors ([#126567](https://github.com/kubernetes/kubernetes/pull/126567), [@fusida](https://github.com/fusida)) [SIG Apps]

    * Custom apiservers built with the latest apiserver library will have the 100MB limit on the body of resource requests as well. The limit can be altered via ServerRunOptions.MaxRequestBodyBytes.
    * The body size limit does not apply to subresources like pods/proxy that proxy request content to another server.

ConfigMap rendering [issue](https://github.com/kubernetes/kubernetes/issues/112081) was found in the 1.25.0 release. When ConfigMaps get updated within the API, they do not get rendered to the resulting pod's filesystem by the Kubelet. The feature has been [reverted to alpha](https://github.com/kubernetes/kubernetes/pull/112078) in the 1.25.1 release.

## Urgent Upgrade Notes

- Fix the regression with the slow pods termination. Before this fix pods may take an additional time to terminate - up to one minute. Reversing the change that ensured that CNI resources cleaned up when the pod is removed on API server.

From Kubernetes 1.20 onwards, SIG Architecture will implement a new policy to transition all REST APIs out of beta within nine months. The idea behind the new policy is to avoid features staying in beta for a long time. Once a new API enters beta, it will have nine months to either:

 - reach GA, and deprecate the beta, or
 - have a new beta version _(and deprecate the previous beta)_.
