- E2e framework: added `--report-complete-ginkgo` and `--report-complete-junit` parameters. They work like `ginkgo --json-report <report dir>/ginkgo/report.json --junit-report <report dir>/ginkgo/report.xml`.

- Events reported for container creation, start, and stop now report the container name in the message and are more consistently formatted. ([#73892](https://github.com/kubernetes/kubernetes/pull/73892), [@smarterclayton](https://github.com/smarterclayton))

	// Dealing with error returns from close() - 'man 2 close'
	//
	// A careful programmer will check the return value of close(), since it is quite possible that
	// errors on a previous write(2) operation are reported only on the final close() that releases
	// the open file descriptor.
	//
	// Failing to check the return value when closing a file may lead to silent loss of data.

- Number of errors reported to the metric `storage_operation_duration_seconds_count` for emptyDir decreased significantly because previously one error was reported for each projected volume created.

regression that could incorrectly reject pods with `OutOfCpu` errors if they were rapidly scheduled after other pods were reported as complete in the API. The Kubelet now waits to report the phase of a pod as terminal in the API until all running containers are guaranteed to have stopped and no new containers can be started.  Short-lived pods may take slightly longer (~1s) to report Succeeded or Failed after this change. ([#108366](https://github.com/kubernetes/kubernetes/pull/108366), [@smarterclay...

- Fix the bug that the metrics for the cluster IP allocator are incorrectly reported. ([#110027](https://github.com/kubernetes/kubernetes/pull/110027), [@tksm](https://github.com/tksm)) [SIG Instrumentation]

- QueueingHint implementation for NodeAffinity is reverted because we found potential scenarios where events that make Pods schedulable could be missed. ([#122327](https://github.com/kubernetes/kubernetes/pull/122327), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]

    * Old behavior:
      * environment variables explicitly whitelisted via --docker-env-metadata-whitelist were exported as `container_env_*=*`. Default is zero so by default non were exported
      * all docker labels were exported as `container_label_*=*`
    * New behavior:
      * Only `container_name`, `pod_name`, `namespace`, `id`, `image`, and `name` labels are exposed
