- Kubeadm: Added missing cluster-info context validation to prevent panics when the user has a malformed kubeconfig in the cluster-info ConfigMap that excludes a valid current context. ([#134715](https://github.com/kubernetes/kubernetes/pull/134715), [@neolit123](https://github.com/neolit123))

* Fix AWS NLB security group updates where valid security group ports were incorrectly removed ([#68422](https://github.com/kubernetes/kubernetes/pull/68422), [@kellycampbell](https://github.com/kellycampbell))
    * when updating a service or when node changes occur.

* Fix a bug in apiserver that could cause a valid update request to be rejected with a precondition check failure. ([#82303](https://github.com/kubernetes/kubernetes/pull/82303), [@roycaihw](https://github.com/roycaihw))

- Kubeadm: avoid panicing if the user has malformed the kubeconfig in the cluster-info config map to not include a valid current context. Include proper validation at the appropriate locations and throw errors instead.

- Kube-scheduler: fixes a 1.29.5 regression that can lead to a scheduler crash when processing pods with affinity that doesn't match a real/valid node ([#125041](https://github.com/kubernetes/kubernetes/pull/125041), [@AxeZhan](https://github.com/AxeZhan)) [SIG Scheduling and Testing]

// the i-th server in this will be applied the i-th policy in `rolePolicies`. If

- Support `controlplane` as a valid EgressSelection type in the EgressSelectorConfiguration API. `Master` is deprecated and will be removed in v1.22. ([#95235](https://github.com/kubernetes/kubernetes/pull/95235), [@andrewsykim](https://github.com/andrewsykim)) [SIG API Machinery]
