- Fixes a spurious "namespace not found" error possible in default configurations in 1.30+ when using ValidatingAdmissionPolicy or MutatingAdmissionPolicy to intercept namespaced objects in newly-created namespaces ([#135443](https://github.com/kubernetes/kubernetes/pull/135443), [@lalitc375](https://github.com/lalitc375)) [SIG API Machinery]

### API Change

- 1. PodAffinityTerm includes a namespaceSelector field to allow selecting eligible namespaces based on their labels. 

pod to consume resource files specifying a different namespace than the one the pod is running in. ([#44862](https://github.com/kubernetes/kubernetes/pull/44862), [@liggitt](https://github.com/liggitt))

    * Kubectl commands run inside a pod using a kubeconfig file now use the namespace specified in the kubeconfig file, instead of using the pod namespace. If no kubeconfig file is used, or the kubeconfig does not specify a namespace, the pod namespace is still used as a fallback. ([#...

### Bug or Regression

- Fixes a spurious "namespace not found" error possible in default configurations in 1.30+ when using ValidatingAdmissionPolicy or MutatingAdmissionPolicy to intercept namespaced objects in newly-created namespaces ([#135442](https://github.com/kubernetes/kubernetes/pull/135442), [@lalitc375](https://github.com/lalitc375)) [SIG API Machinery]

- When using `kubectl logs <pod-name>` and the pod is not found, the error message now includes the namespace. Previously, the message would be "Error from server (NotFound): pods "my-pod-name" not found". Now, it reflects the namespace in the message as follows: "Error from server (NotFound): pods "my-pod-name" not found in namespace "default"".

### Other (Cleanup or Flake)

- Improve error message when a pod with user namespaces is created and the runtime doesn't support user namespaces. ([#131783](https://github.com/kubernetes/kubernetes/pull/131783), [@rata](https://github.com/rata)) [SIG Node]
