- Kube-controller-manager: increased the global level for broadcaster's logging to 3 so that users can ignore event messages by lowering the logging level. It reduces information noise. ([#122293](https://github.com/kubernetes/kubernetes/pull/122293), [@mengjiao-liu](https://github.com/mengjiao-liu))

- Migrate some log messages to structured logging in `pkg/volume/plugins.go`. ([#101510](https://github.com/kubernetes/kubernetes/pull/101510), [@huchengze](https://github.com/huchengze))

- Modified log messages that were logged with `"v":0` in JSON output although they were debug messages with a higher verbosity. ([#106978](https://github.com/kubernetes/kubernetes/pull/106978), [@pohly](https://github.com/pohly))

            For example, if you want that resource to appear in a specific package
            ({@code org.apache.maven.messages}), you must specify this
            element with this value: {@code org/apache/maven/messages}.
            This is not required if you simply put the resources in that directory
            structure at the source, however.

- Resolves spurious `Failed to list *v1.Secret` or `Failed to list *v1.ConfigMap` messages in kubelet logs. ([#99538](https://github.com/kubernetes/kubernetes/pull/99538), [@liggitt](https://github.com/liggitt)) [SIG Auth and Node]
- Sync node status during kubelet node shutdown.

### Other (Cleanup or Flake)

- Fixes the flooding warning messages about setting volume ownership for configmap/secret volumes ([#92878](https://github.com/kubernetes/kubernetes/pull/92878), [@jvanz](https://github.com/jvanz)) [SIG Instrumentation, Node and Storage]

Cgo takes a different approach. It determines the meaning of C
identifiers not by parsing C code but by feeding carefully constructed
programs into the system C compiler and interpreting the generated
error messages, debug information, and object files. In practice,
parsing these is significantly less work and more robust than parsing
C source.

Cgo first invokes gcc -E -dM on the preamble, in order to find out

	// authZ plugin is set, role policies are just claims sent to
	// the plugin and they need not exist.
	//
	// If some mapped policies do not exist, we print some error
	// messages but continue any way - they can be fixed in the
	// running server by creating the policies after start up.
	for arn, rolePolicies := range m {
		specifiedPoliciesSet := newMappedPolicy(rolePolicies).policySet()

		config.EnvSecretKey,
		config.EnvRootUser,
		config.EnvRootPassword,
	} {
		os.Unsetenv(env)
	}

	// Set as non-distributed.
	globalIsDistErasure = false

	// Disable printing console messages during tests.
	color.Output = io.Discard
	// Disable Error logging in testing.
	logger.DisableLog = true

	// Uncomment the following line to see trace logs during unit tests.
	// logger.AddTarget(console.New())

    enabled by calling `tf.debugging.is_traceback_filtering_enabled()`.

    Note that this feature is only available with Python 3.7 or higher.

    *   Improve the informativeness of error messages raised by Keras
        `Layer.__call__()`, by adding the full list of argument values passed to
        the layer in every exception.

*   Introduce the `tf.compat.v1.keras.utils.track_tf1_style_variables`
