- Changed metadata management for Pods to populate `.metadata.generation` on writes. New pods will have a `metadata.generation` of 1; updates to mutable fields in the Pod `.spec` will result in `metadata.generation` being incremented by 1. ([#130181](https://github.com/kubernetes/kubernetes/pull/130181), [@natasha41575](https://github.com/natasha41575)) [SIG Apps, Node and Testing]

- Fixed issue with incremental id generation for `loadbalancer` and `endpoint` in `kubeproxy` mock test framework. ([#120723](https://github.com/kubernetes/kubernetes/pull/120723), [@princepereira](https://github.com/princepereira))

- 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))

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

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.

* add goroutine to move unschedulable pods to activeq if they are not retried for more than 1 minute ([#72558](https://github.com/kubernetes/kubernetes/pull/72558), [@denkensk](https://github.com/denkensk))

  previous releases. When this happens, a `LifecycleHTTPFallback` event is recorded
  in the namespace of the pod and a `kubelet_lifecycle_handler_http_fallbacks_total`
  metric in the kubelet is incremented. Cluster administrators can opt out of the
  expanded lifecycle handler capabilities by setting
  `--feature-gates=ConsistentHTTPGetHandlers=false` in `kubelet`.'
