- The `wait.Poll*` and `wait.ExponentialBackoff*` functions have been deprecated and will be removed in a future release.  Callers should switch to using `wait.PollUntilContextCancel`, `wait.PollUntilContextTimeout`,...

`/healthz`, `/pods` and `/configz` by granting the caller `nodes/proxy` permission in RBAC but that also grants the caller permissions to exec, run and attach to containers on the nodes and doing so does not follow the least privilege principle. Granting callers more permissions than they need can give attackers an opportunity to escalate privileges.

- This PR added tracing support to the kubelet's read-only endpoint, which currently
  does not have tracing. It makes use of the `WithPublicEndpoint` option to prevent callers
  from influencing sampling decisions. ([#121770](https://github.com/kubernetes/kubernetes/pull/121770), [@frzifus](https://github.com/frzifus)) [SIG Node]

contain information about the resource - by default it will be the object metadata, but callers can add the ?includeObject=Object query parameter and receive the full object. In the future kubectl will use this to retrieve the results of `kubectl get`. ([#40848](https://github.com/kubernetes/kubernetes/pull/40848), [@smarterclayton](https://github.com/smarterclayton))

* The behavior of some watch calls to the server when filtering on fields was incorrect. If watching objects with a filter,...

  - Speed up binpacking by reducing the number of PreFilter calls (call once per pod instead of #pods*#nodes times)
  - Speed up finding unneeded nodes by 5x+ in very large clusters by reducing the number of PreFilter calls
  - Expose `--max-nodes-total` as a metric
  - Errors in `IncreaseSize` changed from type `apiError` to `cloudProviderError`

Provided that they can be inferred, type argument lists may be omitted entirely if the function is:
</p>

<ul>
<li>
	<a href="#Calls">called</a> with ordinary arguments,
</li>
<li>
	<a href="#Assignment_statements">assigned</a> to a variable with a known type
</li>
<li>
	<a href="#Calls">passed as an argument</a> to another function, or
</li>
<li>
	<a href="#Return_statements">returned as a result</a>.

- Informer/reflector callers can now catch and unwrap specific API errors by type. ([#110076](https://github.com/kubernetes/kubernetes/pull/110076), [@karlkfi](https://github.com/karlkfi))

- Fixed two regressions introduced by the PodDisruptionConditions feature (on by default in 1.26):
  - pod eviction API calls returned spurious precondition errors and required a second evict API call to succeed

### Bug or Regression

- Avoid GCE API calls when initializing GCE CloudProvider for Kubelets.

* Audit logs might impact the API server performance and the latency of large request and response calls. The issue is observed under the following conditions: if `AdvancedAuditing` feature gate is enabled, which is the default case, if audit logging uses the log backend in JSON format, or if the audit policy records large API calls for requests or responses.
