### Production images moved to community control

As of Kuberenetes v1.19, Kubernetes container images are stored on a community-controlled storage bucket, 
located at `{asia,eu,us}.gcr.io/k8s-artifacts-prod`. The `k8s.gcr.io` vanity domain has been updated 
to this new bucket. This brings production artifacts under community control.

### KubeSchedulerConfiguration graduates to Beta

The focus of this release is **compatibility** with Pydantic v1 and v2, to make sure your current apps keep working. Later there will be more focus on refactors, correctness, code improvements, and then **performance** improvements. Some third-party early beta testers that ran benchmarks on the beta releases of FastAPI reported improvements of **2x - 3x**. Which is not bad for just doing `pip install --upgrade fastapi pydantic`. This was not an official benchmark and I didn't check it myself,...

### Documentation

- Enhanced clarity in error messaging when waiting for volume creation ([#118262](https://github.com/kubernetes/kubernetes/pull/118262), [@torredil](https://github.com/torredil)) [SIG Apps and Storage]

### Failing Test

- API Server Tracing now includes a variety of new spans and span events. ([#113172](https://github.com/kubernetes/kubernetes/pull/113172), [@dashpole](https://github.com/dashpole)) [SIG API Machinery, Architecture, Auth, Instrumentation, Network, Node and Scheduling]

- VSphere releases less than 7.0u2 are not supported for in-tree vSphere volume  as of Kubernetes...

- Kubelet: close a loophole where static pods could reference arbitrary ResourceClaims. The pods created by the kubelet then don't run due to a sanity check, but such references shouldn't be allowed regardless.
