### Serverside Apply - Beta 2

Server-side Apply was promoted to Beta in 1.16, but is now introducing a second Beta in 1.18. This new version will track and manage changes to fields of all new Kubernetes objects, allowing you to know what changed your resources and when.

### Extending Ingress with and replacing a deprecated annotation with IngressClass

- Added `kubelet` Topology Manager metrics to track admission requests processed and occured admission errors. ([#115137](https://github.com/kubernetes/kubernetes/pull/115137), [@swatisehgal](https://github.com/swatisehgal))

### Feature

- A client-go metric, rest_client_exec_plugin_call_total, has been added to track total calls to client-go credential plugins. ([#98892](https://github.com/kubernetes/kubernetes/pull/98892), [@ankeesler](https://github.com/ankeesler)) [SIG API Machinery, Auth, Cluster Lifecycle and Instrumentation]

   * - System.nanoTime() is expensive enough that we want to call it the minimum required number of
   *   times, typically once before invoking a blocking method. This often requires keeping track of
   *   the first time in a method that nanoTime() has been invoked, for which the special value 0L
   *   is reserved to mean "uninitialized". If timeout is non-positive, then nanoTime need never be
   *   called.

- Kubeadm: modified the etcd static Pod `liveness` and `readiness` probes to use a new etcd `v3.5.3+` HTTP(s) health check endpoint `/health?serializable=true` that allows to track the health of individual etcd members and not fail all members if a single member is not healthy in the etcd cluster. ([#110072](https://github.com/kubernetes/kubernetes/pull/110072), [@neolit123](https://github.com/neolit123))

- Added a new Priority and Fairness metric `apiserver_flowcontrol_request_dispatch_no_accommodation_total` to track the number of times a request dispatch attempt results in a no-accommodation status due to lack of available seats.
