- In a scheduler with `Permit` plugins, when a Pod is rejected during `WaitOnPermit`, the scheduler records the plugin.
  The scheduler will use the record to honor cluster events and queueing `hints registered` for the plugin, to inform whether to retry the pod. ([#119785](https://github.com/kubernetes/kubernetes/pull/119785), [@sanposhiho](https://github.com/sanposhiho))

- When an unsupported PodDisruptionBudget configuration is found, an event and log will be emitted to inform users of the misconfiguration. ([#115861](https://github.com/kubernetes/kubernetes/pull/115861), [@JayKayy](https://github.com/JayKayy)) [SIG Apps]

* Fixed an issue with informers missing an `Added` event if a recently deleted object was immediately recreated at the same time the informer dropped a watch and relisted. ([#83911](https://github.com/kubernetes/kubernetes/pull/83911), [@matte21](https://github.com/matte21))

- 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]

From (1) a compiler can infer that the type argument for <code>S</code> is <code>Slice</code>.
Similarly, because the underlying type of <code>Slice</code> is <code>[]int</code>
and <code>[]int</code> must match <code>[]E</code> of the constraint,
a compiler can infer that <code>E</code> must be <code>int</code>.
Thus, for these two equations, type inference infers

  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]

- JSON log output is configurable and now supports writing info messages to stdout and error messages to stderr. Info messages can be buffered in memory. The default is to write both to stdout without buffering, as before. ([#104873](https://github.com/kubernetes/kubernetes/pull/104873), [@pohly](https://github.com/pohly))

- 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),...
