For the 1.8 release, SIG Scheduling extended the concept of cluster sharing by introducing
pod priority and pod preemption. These features allow mixing various types of workloads in a single cluster, and help reach
higher levels of resource utilization and availability.
These features are in alpha. SIG Scheduling also improved the internal APIs for scheduling and made them easier for other components and external schedulers to use.

## Before Upgrading

Consider the following changes, limitations, and guidelines before you upgrade:

### **API Machinery**

- Kubeadm: ensured waiting for apiserver uses a local client that doesn't reach to the control plane endpoint and instead reaches directly to the local API server endpoint. ([#134269](https://github.com/kubernetes/kubernetes/pull/134269), [@neolit123](https://github.com/neolit123)) [SIG Cluster Lifecycle]

- Featuregate AllowInsecureBackendProxy graduates to GA and unconditionally enabled. ([#99658](https://github.com/kubernetes/kubernetes/pull/99658), [@deads2k](https://github.com/deads2k))
- Increase timeout for pod lifecycle test to reach pod status=ready ([#96691](https://github.com/kubernetes/kubernetes/pull/96691), [@hh](https://github.com/hh))

- Fix throughput when scheduling daemonset pods to reach 300 pods/s, if the configured qps allows it. ([#124753](https://github.com/kubernetes/kubernetes/pull/124753), [@sanposhiho](https://github.com/sanposhiho)) [SIG Scheduling]
