* Added pods-per-core to kubelet. [#25762](https://github.com/kubernetes/kubernetes/pull/25762) ([#25813](https://github.com/kubernetes/kubernetes/pull/25813), [@rrati](https://github.com/rrati))
* promote sourceRange into service spec ([#25826](https://github.com/kubernetes/kubernetes/pull/25826), [@freehan](https://github.com/freehan))

*   The `volume.beta.kubernetes.io/storage-class` annotation is deprecated. It will be removed in a future release. For the StorageClass API object, use v1, and in place of the annotation use `v1.PersistentVolumeClaim.Spec.StorageClassName` and `v1.PersistentVolume.Spec.StorageClassName` instead.

- Setting the `status.loadBalancer` of a Service whose `spec.type` is not `LoadBalancer` was previously allowed, but any update to the `metadata` or `spec` would wipe that field. Setting this field is no longer permitted unless `spec.type` is  `LoadBalancer`.  In the very unlikely event that this has unexpected impact, you can enable the `AllowServiceLBStatusOnNonLB` feature gate, which will restore...

### Checking the current `root_path` { #checking-the-current-root-path }

You can get the current `root_path` used by your application for each request, it is part of the `scope` dictionary (that's part of the ASGI spec).

Here we are including it in the message just for demonstration purposes.
