### Structured logging

SIG Instrumentation standardized the structure of log messages and references to Kubernetes objects. Structured logging makes parsing, processing, storing, querying and analyzing logs easier. New methods in the klog library enforce log message structure.

- Fixed a missing status prefix in custom resource validation error messages. ([#123822](https://github.com/kubernetes/kubernetes/pull/123822), [@JoelSpeed](https://github.com/JoelSpeed))
- Fixed a race condition in kube-controller-manager and the scheduler, caused by

        InvalidAccessTokenException exception = new InvalidAccessTokenException(type, message);

        assertEquals("", exception.getType());
        assertEquals(message, exception.getMessage());
        assertNull(exception.getCause());
    }

    public void test_constructor_withEmptyMessage() {
        // Test constructor with empty message string
        String type = "JWT";
        String message = "";

- Changed the error message of `kubectl rollout restart` when subsequent `kubectl rollout restart` commands are executed within a second ([#113040](https://github.com/kubernetes/kubernetes/pull/113040), [@ardaguclu](https://github.com/ardaguclu))

- kubeadm: Improved `kubeadm init` and `kubeadm join` to provide consistent error messages when the kubelet failed or when failed to wait for control plane components. ([#130040](https://github.com/kubernetes/kubernetes/pull/130040), [@HirazawaUi](https://github.com/HirazawaUi))

- Previously, the pod name and namespace were eliminated in the event log message. This PR attempts to add the preemptor pod UID in the preemption event message logs for easier debugging and safer transparency.
