- Fixed a race condition between `Run()` and `SetTransform()` and `SetWatchErrorHandler()` in shared informers. ([#117870](https://github.com/kubernetes/kubernetes/pull/117870), [@howardjohn](https://github.com/howardjohn)) [SIG API Machinery]

- Add the metric `container_oom_events_total` to kubelet's cAdvisor metric endpoint. ([#108004](https://github.com/kubernetes/kubernetes/pull/108004), [@jonkerj](https://github.com/jonkerj))
- Added `SetTransform` to `SharedInformer` to allow users to transform objects before they are stored. ([#107507](https://github.com/kubernetes/kubernetes/pull/107507), [@alexzielenski](https://github.com/alexzielenski))
