- Extend kube-apiserver /readyz with new "informer-sync" check ensuring that internal informers are synced. ([#92644](https://github.com/kubernetes/kubernetes/pull/92644), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Testing]

* NodeController waits for informer sync before doing anything ([#34809](https://github.com/kubernetes/kubernetes/pull/34809), [@gmarek](https://github.com/gmarek))

- Fixed a long-standing issue where `kubelet` rejected Pods with `NodeAffinityFailed` due to a stale informer cache. ([#134445](https://github.com/kubernetes/kubernetes/pull/134445), [@natasha41575](https://github.com/natasha41575))

* Only wait for cache syncs once in NodeController ([#34851](https://github.com/kubernetes/kubernetes/pull/34851), [@ncdc](https://github.com/ncdc))
* NodeController waits for informer sync before doing anything ([#34809](https://github.com/kubernetes/kubernetes/pull/34809), [@gmarek](https://github.com/gmarek))

- Removed scheduler names from preemption event messages. ([#114980](https://github.com/kubernetes/kubernetes/pull/114980), [@mimowo](https://github.com/mimowo))

  a bug in the transforming informer during the Resync operation, 
  by making the transforming function idempotent. ([#124352](https://github.com/kubernetes/kubernetes/pull/124352), [@wojtek-t](https://github.com/wojtek-t)) [SIG API Machinery and Scheduling]

*   [beta] API chunking via the limit and continue request parameters is promoted to beta in this release. Client libraries using the Informer or ListWatch types will automatically opt in to chunking.
