- 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]

- 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]

* 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))

- `kubectl` will not print events if `--show-events=false` argument is passed to
  describe PVC subcommand. ([#120380](https://github.com/kubernetes/kubernetes/pull/120380), [@MaGaroo](https://github.com/MaGaroo))
- `scheduler`: Fixed missing field `apiVersion` from events reported by the taint

- Improved the efficiency of NodeAdded QueueingHint by registering UpdateNodeTaint event for plugins that have NodeAdded event but don't have UpdateNodeTaint event. This ensures better requeuing efficiency and prevents Pods from being stuck in the unschedulable pod pool.
