  /**
   * Creates an {@code ImmutableMap<String, String>} from a {@code Properties} instance. Properties
   * normally derive from {@code Map<Object, Object>}, but they typically contain strings, which is
   * awkward. This method lets you get a plain-old-{@code Map} out of a {@code Properties}.
   *
   * @param properties a {@code Properties} object to be converted

*   The Kubelet's feature gates are now specified as a map when provided via a JSON or YAML KubeletConfiguration, rather than as a string of key-value pairs, making them less awkward for users. ([#53025](https://github.com/kubernetes/kubernetes/pull/53025),[ @mtaufen](https://github.com/mtaufen))

##### **Other**

- In the `kubectl describe` output, the fields with names containing special characters are now displayed as-is without any pretty formatting, avoiding awkward outputs.  ([#75483](https://github.com/kubernetes/kubernetes/pull/75483), [@gsadhani](https://github.com/gsadhani))
