- Fix a bug where events/v1 Events with similar event type and reporting instance were not aggregated by client-go. ([#112365](https://github.com/kubernetes/kubernetes/pull/112365), [@dgrisonnet](https://github.com/dgrisonnet)) [SIG API Machinery and Instrumentation]

`audit.k8s.io/v1beta1` and `audit.k8s.io/v1alpha1` audit policy configuration and audit events are deprecated in favor of `audit.k8s.io/v1`, available since v1.13. kube-apiserver invocations that specify alpha or beta policy configurations with `--audit-policy-file`, or explicitly request alpha or beta audit events with `--audit-log-version` / `--audit-webhook-version` must update to use `audit.k8s.io/v1` and accept `audit.k8s.io/v1` events prior to v1.24. ([#98858](https://github.com/kubernetes/kubernetes/pull/98858),...

- Fix a 1.28 regression in scheduler: a pod with concurrent events could incorrectly get moved to the unschedulable queue where it could got stuck until the next periodic purging after 5 minutes if there was no other event for it. ([#120445](https://github.com/kubernetes/kubernetes/pull/120445), [@pohly](https://github.com/pohly)) [SIG Scheduling]

- Fix kubectl printer to correctly handle timestamps of events emitted using events.k8s.io API ([#94226](https://github.com/kubernetes/kubernetes/pull/94226), [@ingvagabund](https://github.com/ingvagabund)) [SIG CLI]
  ```sh
  $ kubectl get event
  LAST SEEN   TYPE     REASON              OBJECT                        MESSAGE

* Fix watch to not send the same set of events multiple times causing watcher to go back in time ([#73845](https://github.com/kubernetes/kubernetes/pull/73845), [@wojtek-t](https://github.com/wojtek-t))
* fixes an error processing watch events when running skewed apiservers ([#73482](https://github.com/kubernetes/kubernetes/pull/73482), [@liggitt](https://github.com/liggitt))

* add support for client-side spam filtering of events ([#47367](https://github.com/kubernetes/kubernetes/pull/47367), [@derekwaynecarr](https://github.com/derekwaynecarr))
* Provide a way to omit Event stages in audit policy ([#49280](https://github.com/kubernetes/kubernetes/pull/49280), [@CaoShuFeng](https://github.com/CaoShuFeng))
