## Dependencies

### Added

* Fixes a bug where if an error was returned that was not an `autorest.DetailedError` we would return `"not found", nil` which caused nodes to go to `NotReady` state. ([#57484](https://github.com/kubernetes/kubernetes/pull/57484), [@brendandburns](https://github.com/brendandburns))

### Other (Cleanup or Flake)

- Fixes bug in CronJob Controller V2 where it would lose track of jobs upon job template labels change. ([#107997](https://github.com/kubernetes/kubernetes/pull/107997), [@d-honeybadger](https://github.com/d-honeybadger))
- If drainer has nil for Ctx or Client it will error with `RunCordonOrUncordon`. ([#105297](https://github.com/kubernetes/kubernetes/pull/105297), [@jackfrancis](https://github.com/jackfrancis))

- A customizable `OrderedScoreFuncs()` function was introduced. Out-of-tree plugins 
  that used the scheduler's preemption interface could implement this function
  for custom preemption preferences or return nil to keep the current behavior. ([#121867](https://github.com/kubernetes/kubernetes/pull/121867), [@lianghao208](https://github.com/lianghao208))
