### **Cluster Lifecycle**

  `volume_manager_total_volumes`
  ([#84907](https://github.com/kubernetes/kubernetes/pull/84907), [@RainbowMango](https://github.com/RainbowMango))
- Deprecated metric `rest_client_request_latency_seconds` has been turned off. ([#83836](https://github.com/kubernetes/kubernetes/pull/83836), [@RainbowMango](https://github.com/RainbowMango))
- Following metrics from kubelet are now marked as with the ALPHA stability level:

  
  When we switched to go-runner for building the apiserver,
  controller-manager, and scheduler server components, we no longer
  reference the individual architectures in the image names, specifically
  in the 'FROM' directive of the server image Dockerfiles.
  
  As a result, server images for non-amd64 images copy in the go-runner
  amd64 binary instead of the go-runner that matches that architecture.
  

 - [kube-log-runner](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/component-base/logs/kube-log-runner) is included in release tar balls. It can be used to replace the deprecated `--log-file` parameter. ([#106123](https://github.com/kubernetes/kubernetes/pull/106123), [@pohly](https://github.com/pohly))...

* kube-apiserver now uses SSH tunnels for webhooks if the webhook is not directly routable from apiserver's network environment. ([#58644](https://github.com/kubernetes/kubernetes/pull/58644), [@yguo0905](https://github.com/yguo0905))

    * + to use:
    * A new service spec field `Service.Spec.IPFamily` has been added. The default of this field is family of (first service cidr in --service-cluster-ip-range flag). The value is defaulted as described above  once the feature gate is turned on. Here are the possible values for this field:

- The feature-gate CSIMigrationPortworx was promoted to beta in Kubernetes 1.25, but turned off by default. In 1.31, it was turned on by default. Before upgrading to 1.31, please make sure that the corresponding portworx csi driver is installed if you are using Portworx.
