- Removed general available feature gate `CPUManager`. ([#129296](https://github.com/kubernetes/kubernetes/pull/129296), [@carlory](https://github.com/carlory)) [SIG API Machinery, Node and Testing]

- When the kubelet fails to assign CPUs to a Pod because there less available CPUs than the Pod requests, the error message changed from
  `not enough cpus available to satisfy request` to `not enough cpus available to satisfy request: <num_requested> requested, only <num_available> available`. ([#121059](https://github.com/kubernetes/kubernetes/pull/121059), [@matte21](https://github.com/matte21))

- Fix image pulling failure when IMDS is unavailable in kubelet startup ([#110523](https://github.com/kubernetes/kubernetes/pull/110523), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider]

### Bug or Regression

- Ensure daemonset controller to count old unhealthy pods towards max unavailable budget ([#127776](https://github.com/kubernetes/kubernetes/pull/127776), [@ncdc](https://github.com/ncdc)) [SIG Apps]
