- Kubernetes is now built with go 1.22.8 ([#128129](https://github.com/kubernetes/kubernetes/pull/128129), [@haitch](https://github.com/haitch)) [SIG Release and Testing]

### Bug or Regression

- Ensure daemonset controller to count old unhealthy pods towards max unavailable budget ([#127776](https://github.com/kubernetes/kubernetes/pull/127776), [@ncdc](https://github.com/ncdc)) [SIG Apps]

- Ensured memory resizing for Guaranteed QoS pods on static Memory policy configurations was gated by `InPlacePodVerticalScalingExclusiveMemory` (defaults: `false`). ([#132473](https://github.com/kubernetes/kubernetes/pull/132473), [@pravk03](https://github.com/pravk03)) [SIG Node, Scheduling and Testing]

Federated HPAs are similar to the traditional Kubernetes HPAs, except
that they span multiple clusters. Creating a Federated HPA targeting
multiple clusters ensures that cluster-level autoscalers are
consistently deployed across those clusters, and dynamically managed
to ensure that autoscaling can occur optimially in all clusters,
within a set of global constraints on the total number of replicas

### Bug or Regression

- Do not fail sorting empty elements. ([#94666](https://github.com/kubernetes/kubernetes/pull/94666), [@soltysh](https://github.com/soltysh)) [SIG CLI]
- Ensure getPrimaryInterfaceID not panic when network interfaces for Azure VMSS are null ([#94801](https://github.com/kubernetes/kubernetes/pull/94801), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]

- Kubeadm: during join when a check is performed that a Node with the same name already exists in the cluster, make sure the NodeReady condition is properly validated ([#89602](https://github.com/kubernetes/kubernetes/pull/89602), [@kvaps](https://github.com/kvaps)) [SIG Cluster Lifecycle]

the semaphore.
This is a common idiom for limiting concurrency.
</p>

<p>
This program starts a goroutine for every entry in the work list, but the
goroutines coordinate using the <code>limit</code> channel to ensure
that at most three are running work functions at a time.
</p>

<pre>
var limit = make(chan int, 3)

func main() {
	for _, w := range work {
		go func(w func()) {
			limit &lt;- 1
			w()

### Other notable changes

* kube-up (with gce/gci and gce/coreos providers) now ensures the authentication token file contains correct tokens for the control plane components, even if the file already exists (ensures upgrades and downgrades work successfully) ([#43676](https://github.com/kubernetes/kubernetes/pull/43676), [@liggitt](https://github.com/liggitt))

   * reference; instead use the reference this method <i>returns</i>. At runtime, these point to the
   * same instance, but only the returned reference has the correct generic type information to
   * ensure type safety. For best results, use the standard method-chaining idiom illustrated in the
   * class documentation above, configuring a builder and building your cache in a single statement.
