- 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))

*   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**

* Make kubelet ReadLogs backward compatible. ([#63268](https://github.com/kubernetes/kubernetes/pull/63268), [@Random-Liu](https://github.com/Random-Liu))

  * Rescheduler relies on taints, which were changed in a backward incompatible way. Rescheduler 0.3 shipped together with Kubernetes 1.6 understands the new taints and will clean up the old annotations, but Rescheduler 0.2 shipped together with Kubernetes 1.5 doesn't understand the new taints. In order to avoid...

- Updated google.golang.org/protobuf to `v1.33.0` to resolve `CVE-2024-24786`. ([#123758](https://github.com/kubernetes/ku...

### Feature

- ACTION REQUIRED : In CoreDNS v1.7.0, [metrics names have been changed](https://github.com/coredns/coredns/blob/master/notes/coredns-1.7.0.md#metric-changes) which will be backward incompatible with existing reporting formulas that use the old metrics' names. Adjust your formulas to the new names before upgrading. 
  
  Kubeadm now includes CoreDNS version v1.7.0. Some of the major changes include:

  // HTTPGet specifies the http request to perform.
  // +optional
  optional HTTPGetAction httpGet = 2;

  // Deprecated. TCPSocket is NOT supported as a LifecycleHandler and kept
  // for the backward compatibility. There are no validation of this field and
  // lifecycle hooks will fail in runtime when tcp handler is specified.
  // +optional
  optional TCPSocketAction tcpSocket = 3;
}

imaginary_lit = (decimal_digits | int_lit | float_lit) "i" .
</pre>

<p>
For backward compatibility, an imaginary literal's integer part consisting
entirely of decimal digits (and possibly underscores) is considered a decimal
integer, even if it starts with a leading <code>0</code>.
</p>

<pre>
0i
0123i         // == 123i for backward-compatibility
0o123i        // == 0o123 * 1i == 83i
0xabci        // == 0xabc * 1i == 2748i

  
  Having appropriate QueueingHintFn contributes to reducing useless retries and thus improves the overall scheduler's performance.
  
  **How can I migrate?**
  
  For backward compatibility, nil `QueueingHintFn` is treated as always returning QueueAfterBackoff. 
  So, if you want to just keep the existing behavior, you can register `ClusterEventWithHint` with no `QueueingHintFn` in it. 

    * Add metrics `*_admission_latencies_milliseconds` and `*_admission_latencies_milliseconds_summary` for backward compatible, but will be removed in a future release.
