  - pod eviction API calls returned spurious precondition errors and required a second evict API call to succeed
  - dry-run eviction API calls persisted a DisruptionTarget condition into the pod being evicted ([#116554](https://github.com/kubernetes/kubernetes/pull/116554), [@atiratree](https://github.com/atiratree))

- Protobuf serialization of metav1.MicroTime timestamps (used in `Lease` and `Event` API objects) has been corrected to truncate to microsecond precision, to match the documented behavior and JSON/YAML serialization. Any existing persisted data is truncated to microsecond when read from etcd. ([#111936](https://github.com/kubernetes/kubernetes/pull/111936), [@haoruan](https://github.com/haoruan)) [SIG API Machinery]

### Feature

- New configuration is introduced to the kubelet that allows it to track container images and the list of authentication information that leads to their successful pulls. This data is persisted across reboots of the host and restarts of the kubelet.
  

- Fix kubectl printer to correctly handle timestamps of events emitted using events.k8s.io API ([#94226](https://github.com/kubernetes/kubernetes/pull/94226), [@ingvagabund](https://github.com/ingvagabund)) [SIG CLI]
  ```sh
  $ kubectl get event

				// Truncate non-empty version and type matches
				if latest.header.VersionID == ver.header.VersionID {
					versions[i] = versions[i][1:]
					continue
				}
				// Skip versions with version id we already emitted.
				for _, mergedV := range merged {
					if ver.header.VersionID == mergedV.header.VersionID {
						versions[i] = versions[i][1:]
						continue
					}
				}
				// Keep top entry (and remaining)...

### Feature

- Kube-apiserver: when merging lists, Server Side Apply now prefers the order of the submitted request instead of the existing persisted object ([#107569](https://github.com/kubernetes/kubernetes/pull/107569), [@jiahuif](https://github.com/jiahuif)) [SIG API Machinery, CLI, Cloud Provider, Cluster Lifecycle, Instrumentation, Storage and Testing]

### Bug or Regression

  - pod eviction API calls returned spurious precondition errors and required a second evict API call to succeed
  - dry-run eviction API calls persisted a DisruptionTarget condition into the pod being evicted ([#116750](https://github.com/kubernetes/kubernetes/pull/116750), [@atiratree](https://github.com/atiratree)) [SIG API Machinery and Testing]
