- Implemented API streaming for the `watch-cache`
  
  When `sendInitialEvents` `ListOption` is set together with `watch=true`, it begins the watch stream with synthetic init events followed by a synthetic "Bookmark" after which the server continues streaming events. ([#110960](https://github.com/kubernetes/kubernetes/pull/110960), [@p0lyn0mial](https://github.com/p0lyn0mial))

* Fixed an issue ([#47800](https://github.com/kubernetes/kubernetes/pull/47800)) where `kubectl logs -f` failed with `unexpected stream type ""`. ([#50381](https://github.com/kubernetes/kubernetes/pull/50381), [@sczizzo](https://github.com/sczizzo))

- The scheduler skips the `PodTopologySpread` Filter plugin if no spread constraints.
  It will affect some metrics values related to the `PodTopologySpread` Filter plugin. ([#117683](https://github.com/kubernetes/kubernetes/pull/117683), [@utam0k](https://github.com/utam0k))

- Text logging in Kubernetes components now uses [textlogger](https://pkg.go.dev/k8s.io/klog/v2@v2.120.0/textlogger). The same split streams of info and error log entries with buffering of info entries is now also supported for text output (off by default, alpha feature). Previously, this was only supported for JSON. Performance is better also without split streams. ([#114672](https://github.com/kubernetes/kubernetes/pull/114672), [@pohly](https://github.com/pohly))

- Added options for configuring `nf_conntrack_udp_timeout`, and `nf_conntrack_udp_timeout_stream` variables of netfilter conntrack subsystem. ([#120808](https://github.com/kubernetes/kubernetes/pull/120808), [@aroradaman](https://github.com/aroradaman))

- Added a method `StreamWithContext` to `remotecommand.Executor` to support cancelable SPDY executor stream. ([#103177](https://github.com/kubernetes/kubernetes/pull/103177), [@arkbriar](https://github.com/arkbriar))
