* This keeps the behavior consistent with Docker integration, and fixes an issue that some container Prometheus metrics don't work when there are summary stats for multiple instances of the same pod.

- Fixed #118052: nodeAffinity on pods can change prior to scheduling gates being removed even when podSpec.affinity is nil in the initial spec, this matches the 1.28 behavior to allow consistent integrators to be written.

  /**
   * When writing a set of headers fails due to an `IOException`, make sure the writer is left

The cri-tools project, which aims to provide consistent tooling for operators to debug and introspect their nodes in production independent of their chosen container runtime, graduated to GA.

- `kubectl apply` now coerces `null` values for labels and annotations in manifests to empty string values, 
consistent with typed JSON metadata decoding, rather than dropping all labels and annotations ([#129257](https://github.com/kubernetes/kubernetes/pull/129257), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

### Feature

* etcd client add dial timeout. ([#61459](https://github.com/kubernetes/kubernetes/pull/61459), [@hzxuzhonghu](https://github.com/hzxuzhonghu))
* nil admission options are now consistent with other nil options. ([#63993](https://github.com/kubernetes/kubernetes/pull/63993), [@tamalsaha](https://github.com/tamalsaha))

* Make watch cache treat resourceVersion consistent with uncached watch ([#24008](https://github.com/kubernetes/kubernetes/pull/24008), [@liggitt](https://github.com/liggitt))

### Other notable changes

- Added `ConsistentListFromCache` feature gate that allows apiserver to serve consistent lists from cache. ([#118508](https://github.com/kubernetes/kubernetes/pull/118508), [@serathius](https://github.com/serathius))
