### SIG Cluster Lifecycle

SIG Cluster Lifecycle focused on improving kubeadm’s user experience by including a set of new commands related to maintaining the kubeadm configuration file, the API version of which has now has been incremented to `v1alpha2`. These commands can handle the migration of the configuration to a newer version, printing the default configuration, and listing and pulling the required container images for bootstrapping a cluster.

<h3 id="IncDec_statements">IncDec statements</h3>

<p>
The "++" and "--" statements increment or decrement their operands
by the untyped <a href="#Constants">constant</a> <code>1</code>.
As with an assignment, the operand must be <a href="#Address_operators">addressable</a>
or a map index expression.

- EndpointSlice generation is now incremented when labels change. ([#99750](https://github.com/kubernetes/kubernetes/pull/99750), [@robscott](https://github.com/robscott)) [SIG Network]

- New plugin_evaluation_total is added to the scheduler.This metric counts how many times the specific plugin affects the scheduling result. The metric does not get incremented when the plugin has nothing to do with an incoming Pod. ([#115082](https://github.com/kubernetes/kubernetes/pull/115082), [@sanposhiho](https://github.com/sanposhiho))

  // accept traffic.
  optional bool ready = 4;

  // RestartCount holds the number of times the container has been restarted.
  // Kubelet makes an effort to always increment the value, but there
  // are cases when the state may be lost due to node restarts and then the value
  // may be reset to 0. The value is never negative.
  optional int32 restartCount = 5;

- Fixes conversion error in multi-version custom resources that could cause metadata.generation to increment on no-op patches or updates of a custom resource. ([#88995](https://github.com/kubernetes/kubernetes/pull/88995), [@liggitt](https://github.com/liggitt)) [SIG API Machinery]

    * a. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[0:3].name
    * b. kubectl get pod test-pod -o custom-columns=CONTAINER:.spec.containers[-2:].name
* scheduler: use incremental scheduling cycle in PriorityQueue to put all in-flight unschedulable pods back to active queue if we received move request ([#73309](https://github.com/kubernetes/kubernetes/pull/73309), [@cofyc](https://github.com/cofyc))

For the 1.8 release, SIG Node continued to focus
on a broad set of workload types, including hardware and performance
sensitive workloads such as data analytics and deep learning. The SIG also
delivered incremental improvements to node reliability.
