- Add three metrics to the job controller to monitor if a job works in healthy condition.
  `IndexedJob` has been promoted to Beta. ([#101292](https://github.com/kubernetes/kubernetes/pull/101292), [@AliceZhang2016](https://github.com/AliceZhang2016))

- Removed `ENABLE_CLIENT_GO_WATCH_LIST_ALPHA` environment variable from the reflector.
  To activate the feature set `KUBE_FEATURE_WatchListClient` environment variable or a corresponding command line option (this works only with binaries that explicitly expose it).

### Structured Logging in Kubelet

Kubelet has adopted structured logging, thanks to community effort in accomplishing this within the release timeline. Structured logging in the project remains an ongoing effort -- for folks interested in participating, [keep an eye / chime in to the mailing list discussion](https://groups.google.com/g/kubernetes-dev/c/y4WIw-ntUR8).

### Storage Capacity Tracking

  unschedulable pod pool. ([#122292](https://github.com/kubernetes/kubernetes/pull/122292), [@sanposhiho](https://github.com/sanposhiho)) [SIG Node, Scheduling, Storage and Testing]
- Fix enabling consistent list from watch cache also works for resourceVersion=0 ([#123676](https://github.com/kubernetes/kubernetes/pull/123676), [@serathius](https://github.com/serathius)) [SIG API Machinery]

- Kube-proxy, kube-scheduler and kubelet have HTTP APIs for changing the logging verbosity at runtime. This now also works for JSON output. ([#114609](https://github.com/kubernetes/kubernetes/pull/114609), [@pohly](https://github.com/pohly)) [SIG API Machinery, Architecture, Cloud Provider, Instrumentation and Testing]

### Feature

- Adding support for multiple --from-env-file flags ([#101646](https://github.com/kubernetes/kubernetes/pull/101646), [@lauchokyip](https://github.com/lauchokyip)) [SIG CLI]
- All folks to build kubernetes with a custom kube-cross image ([#104185](https://github.com/kubernetes/kubernetes/pull/104185), [@dims](https://github.com/dims)) [SIG Release and Testing]

- Scheduler: optionally check for available storage capacity before scheduling pods which have unbound volumes (alpha feature with the new `CSIStorageCapacity` feature gate, only works for CSI drivers and depends on support for the feature in a CSI driver deployment) ([#92387](https://github.com/kubernetes/kubernetes/pull/92387), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps, Auth, Scheduling, Storage and Testing]...
