- Improve Node QueueHint in the NodeAffinty plugin by ignoring unrelated changes that keep pods unschedulable. ([#127444](https://github.com/kubernetes/kubernetes/pull/127444), [@dom4ha](https://github.com/dom4ha)) [SIG Scheduling and Testing]

- In a scheduler with `Permit` plugins, when a Pod is rejected during `WaitOnPermit`, the scheduler records the plugin.
  The scheduler will use the record to honor cluster events and queueing `hints registered` for the plugin, to inform whether to retry the pod. ([#119785](https://github.com/kubernetes/kubernetes/pull/119785), [@sanposhiho](https://github.com/sanposhiho))

- Correct event registration for multiple scheduler plugins; this fixes a potential significant delay in re-queueing unschedulable pods. ([#109442](https://github.com/kubernetes/kubernetes/pull/109442), [@ahg-g](https://github.com/ahg-g))

### Bug or Regression

- Correct event registration for multiple scheduler plugins; this fixes a potential significant delay in re-queueing unschedulable pods. ([#109447](https://github.com/kubernetes/kubernetes/pull/109447), [@ahg-g](https://github.com/ahg-g)) [SIG Scheduling and Testing]

- Etcd image `v3.5.12` has been built. ([#123069](https://github.com/kubernetes/kubernetes/pull/123069), [@bzsuni](https://github.com/bzsuni))
- Fixed a bug in scheduler requeueing where registered wildcard cluster event sources didn't work. ([#123117](https://github.com/kubernetes/kubernetes/pull/123117), [@kerthcet](https://github.com/kerthcet))

- Optimize EC2 DescribeInstances API calls in aws cloud provider library by querying instance ID instead of EC2 filters when possible ([#78140](https://github.com/kubernetes/kubernetes/pull/78140), [@zhan849](https://github.com/zhan849))

* Add support in Kubelet to consume container metrics via CRI. [[@yguo0905](https://github.com/yguo0905)]
  * There are known bugs that result in errors when querying Kubelet's stats summary API. We expect to fix them in v1.8.1.

- Improved scheduling latency when there are many gated pods and events that trigger requeueing from the unschedulable pool. ([#124618](https://github.com/kubernetes/kubernetes/pull/124618), [@gabesaba](https://github.com/gabesaba)) [SIG Scheduling and Testing]
