- Append the image pull error for the pods `status.containerStatuses[*].state.waiting.message` when
  in image pull back-off (`reason` is `ImagePullBackOff`) instead of the generic `Back-off pulling image…` message. ([#127918](https://github.com/kubernetes/kubernetes/pull/127918), [@saschagrunert](https://github.com/saschagrunert)) [SIG Node and Testing]

### Bug or Regression

- Client-go: resolves an issue with informers falling back to full list requests when timeouts are encountered, rather than re-establishing a watch. ([#89977](https://github.com/kubernetes/kubernetes/pull/89977), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

  Previously, when unschedulable Pods are updated, the scheduler always put Pods back to activeQ/backoffQ. But, actually not all updates to Pods make Pods schedulable, especially considering many scheduling constraints nowadays are immutable.
