authentication now supports requiring specific claims with `--oidc-required-claim=<claim>=<value>` Previously, there was no mechanism for a user to specify claims in the OIDC authentication process that were requid to be present in the ID Token with an expected value.

- Scheduler now skips `InterPodAffinity` Filter plugin when `InterPodAffinity` Filter plugin has nothing to do with a Pod.

*   If multiple PodSecurityPolicy objects allow a submitted pod, priority is given to policies that do not require default values for any fields in the pod spec. If default values are required, the first policy ordered by name that allows the pod is used. ([#52849](https://github.com/kubernetes/kubernetes/pull/52849),[ @liggitt](https://github.com/liggitt))

installation processes must be updated with the new path. ([#58171](https://github.com/kubernetes/kubernetes/pull/58171), [@verult](https://github.com/verult))

* Default values differ between the Kubelet's componentconfig (config file) API and the Kubelet's command line. Be sure to review the default values when migrating to using a config file. For example, the authz mode is set to "AlwaysAllow" if you rely on the command line, but defaults to the more secure "Webhook" mode if you load...

([#87580](https://github.com/kubernetes/kubernetes/pull/87580), [@julianvmodesto](https://github.com/julianvmodesto)) [SIG CLI]...

* fix azure pv crash due to volumeSource.ReadOnly value nil ([#54607](https://github.com/kubernetes/kubernetes/pull/54607), [@andyzhangx](https://github.com/andyzhangx))
* kubeadm init: fix a bug that prevented the --token-ttl flag and tokenTTL configuration value from working as expected for infinite (0) values. ([#54640](https://github.com/kubernetes/kubernetes/pull/54640), [@mattmoyer](https://github.com/mattmoyer))
