- Added fields `reason` and `fieldPath` into CRD validation rules to allow users to specify reason and field path when validation failed. ([#118041](https://github.com/kubernetes/kubernetes/pull/118041), [@cici37](https://github.com/cici37)) [SIG API Machinery]

### Feature

- 'Added selector validation to `HorizontalPodAutoscaler`: when multiple HPAs
  select the same set of Pods, scaling now will be disabled for those HPAs with
  the reason `AmbiguousSelector`. This change also covers a case when multiple HPAs
  point to the same deployment.'

### Documentation

- Documented the reason field in CRI API to ensure it equals `OOMKilled` for the containers terminated by OOM killer ([#112977](https://github.com/kubernetes/kubernetes/pull/112977), [@mimowo](https://github.com/mimowo))
