* TokenRequests now are required to have an expiration duration between 10 minutes and 2^32 seconds. ([#63999](https://github.com/kubernetes/kubernetes/pull/63999), [@mikedanese](https://github.com/mikedanese))

* PidPressure evicts pods from lowest priority to highest priority ([#72844](https://github.com/kubernetes/kubernetes/pull/72844), [@dashpole](https://github.com/dashpole))

- Fixed a `v1.28` regression in scheduler: a pod with concurrent events could incorrectly get moved to the unschedulable queue where it could get stuck until the next periodic purging after 5 minutes, if there was no other event for it. ([#120413](https://github.com/kubernetes/kubernetes/pull/120413), [@pohly](https://github.com/pohly))

- Kubeadm increased to 5 minutes its timeout for the TLS bootstrapping process to complete upon join ([#89735](https://github.com/kubernetes/kubernetes/pull/89735), [@rosti](https://github.com/rosti)) [SIG Cluster Lifecycle]

  - Clients should reload the token from disk periodically (once per minute is recommended) to ensure they continue to use a valid token. `k8s.io/client-go` version v11.0.0+ and v0.15.0+ reload tokens automatically.

- Added a mechanism that calculates a digest of etcd and the watch cache every 5 minutes and exposes it as the `apiserver_storage_digest` metric.
