* Protobuf serialization does not distinguish between `[]` and `null`.

- Demoted KEP-5278 feature gates `ClearingNominatedNodeNameAfterBinding` and `NominatedNodeNameForExpectation` to alpha from beta. ([#133293](https://github.com/kubernetes/kubernetes/pull/133293), [@utam0k](https://github.com/utam0k)) [SIG Scheduling and Testing]...

### Bug or Regression

- Disabled a previously on-by-default optimization for the API server where each **watch** response used a dedicated goroutine. The `APIServingWithRoutine` feature gate has been demoted from beta to alpha, and is now off by default. ([#126470](https://github.com/kubernetes/kubernetes/pull/126470), [@benluddy](https://github.com/benluddy)) [SIG API Machinery and Scalability]
