### SIG AWS

In v1.13 we worked on tighter integrations of Kubernetes API objects with AWS services. These include three out-of-tree alpha feature releases:

1) Alpha for AWS ALB (Application Load Balancer) integration to Kubernetes Ingress resources.

- 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))

- The `client-go` dynamic client sets the header `Content-Type: application/json` by default ([#104327](https://github.com/kubernetes/kubernetes/pull/104327), [@sxllwx](https://github.com/sxllwx))
- The `kube-Proxy` now correctly filters out unready endpoints for Services with Topology. ([#106507](https://github.com/kubernetes/kubernetes/pull/106507), [@robscott](https://github.com/robscott))

- Both apiserver_request_duration_seconds metrics and RequestReceivedTimestamp fields of an audit event now take into account the time a request spends in the apiserver request filters. ([#94903](https://github.com/kubernetes/kubernetes/pull/94903), [@tkashem](https://github.com/tkashem))
- Build/lib/release: Explicitly use '--platform' in building server images
  

- When a PreFilterResult filters out certain Nodes, the scheduling framework now categorizes them as rejected via `UnschedulableAndUnresolvable`. Consequently, these nodes are excluded from the candidates for the preemption process. Additionally, this update corrects how the scheduling...

- API Server tracing now includes the latency of authorization, priorityandfairness, impersonation, audit, and authentication filters. ([#113217](https://github.com/kubernetes/kubernetes/pull/113217), [@dashpole](https://github.com/dashpole))
