* [GCP kube-up.sh] Variables that were part of kube-env that were only used for kubelet flags are no longer being set, and are being replaced by the more portable mechanism of the kubelet configuration file. The individual variables in the kube-env metadata entry were never meant to be a stable interface and this release note only applies if you are depending on them. ([#60020](https:...

- `kubectl apply --server-dry-run` is deprecated and replaced with --dry-run=server ([#87580](https://github.com/kubernetes/kubernetes/pull/87580), [@julianvmodesto](https://github.com/julianvmodesto)) [SIG CLI]

#### add-ons:

- Deprecate `--record` flag in `kubectl`. The `--record` flag is being replaced with the [mechanism](https://github.com/kubernetes/enhancements/tree/master/keps/sig-cli/859-kubectl-headers) which annotates HTTP requests with kubectl command details. ([#102873](https://github.com/kubernetes/kubernetes/pull/102873), [@soltysh...

- Some apiserver metrics were changed, as follows.
  - `priority_level_seat_count_samples` is replaced with `priority_level_seat_utilization`, which samples every nanosecond rather than every millisecond; the old metric conveyed utilization despite its name.
  - `priority_level_seat_count_watermarks` is removed.

			return x.setIdx(i, ventry)

			return x.setIdx(i, ventry)
		case DeleteType:
			// Allowing delete marker to replaced with proper
			// object data type as well, this is not S3 complaint
			// behavior but kept here for future flexibility.
			return x.setIdx(i, ventry)
		}
	}

	// We did not find it, add it.

- The `StorageCapacityScoring` feature gate was added to score nodes by available storage capacity. It's in alpha and disabled by default. The `VolumeCapacityPriority` alpha feature was replaced with this, and the default behavior was changed. The `VolumeCapacityPriority` preferred a node with the least allocatable, but the `StorageCapacityScoring` preferred a node with the maximum allocatable. See [KEP-4049](https://github.com/kubernet...

* Scheduling conformance tests related to daemonsets should set the annotation that relaxes node selection restrictions, if any are set. This ensures conformance tests can run on a wider array of clusters. ([#68793](https://github.com/kubernetes/kubernetes/pull/68793), [@aveshagarwal](https://github.com/aveshagarwal))
