- The fallback behavior of the Downward API's `resourceFieldRef` field was updated to account for pod-level resources: if container-level limits were not set, pod-level limits were now used before falling back to node allocatable resources.

scalability testing in a continuous integration (CI) environment. The SIG
defined a concrete process for scalability testing, created
documentation for the current scalability thresholds, and defined a new set of
Service Level Indicators (SLIs) and Service Level Objectives (SLOs) for the system.
Here's the release [scalability validation report].

*   Added pod-level local ephemeral storage metric to the Summary API. Pod-level ephemeral storage reports the total filesystem usage for the containers and emptyDir volumes in the measured Pod.

- Changed the Pod API to support `hugepage resources` at `spec` level for pod-level resources. ([#130577](https://github.com/kubernetes/kubernetes/pull/130577), [@KevinTMtz](https://github.com/KevinTMtz)) [SIG Apps, CLI, Node, Scheduling, Storage and Testing]

- The kube-apiserver will no longer serve APIs that should have been deleted in GA non-alpha levels.  Alpha levels will continue to serve the removed APIs so that CI doesn't immediately break. ([#96525](https://github.com/kubernetes/...

* Exposed `/debug/flags/v` to allow dynamically set glog logging level.  For example, to change glog level to 3, send a PUT request such as `curl -X PUT http://127.0.0.1:8080/debug/flags/v -d "3"`.

We also enabled [audience validation in TokenReview](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.13/#tokenreview-v1-authentication-k8s-io) for the new tokens for improved scoping. Under audit logging, the new alpha-level "dynamic audit configuration" adds support for [dynamically registering webhooks to receive...
