- The `controller.kubernetes.io/pod-deletion-cost` annotation can be set to offer a hint on the cost of deleting a `Pod` compared to other pods belonging to the same ReplicaSet. Pods with lower deletion cost are deleted first. This is an alpha feature. ([#99163](https://github.com/kubernetes/kubernetes/pull/99163), [@ahg-g](https://github.com/ahg-g))...

- Added validation to ensure that if `service.kubernetes.io/topology-aware-hints` and `service.kubernetes.io/topology-mode` annotations are both set, they are set to the same value.Also Added deprecation warning if `service.kubernetes.io/topology-aware-hints` annotation is used.

- Fixed Cronjob `status.lastSuccessfulTime` not populated by a manually triggered ([#118530](https://github.com/kubernetes/kubernetes/pull/118530), [@carlory](https://github.com/carlory))
- Fixed Topology Aware Hints not working when the `topology.kubernetes.io/zone` label is added after Node creation. ([#117245](https://github.com/kubernetes/kubernetes/pull/117245), [@tnqn](https://github.com/tnqn))

    version 1.9. Extended Resources (ERs) are a drop-in replacement for OIRs. You can use
    any domain name prefix outside of the `kubernetes.io/` domain instead of the
    `pod.alpha.kubernetes.io/opaque-int-resource-` prefix.

## Notable Features

### Workloads API (apps/v1beta2)

Kubernetes 1.8 adds the apps/v1beta2 group and version, which now consists of the

- The `TopologyAwareHints` feature gate is now enabled by default. This will allow users to opt-in to Topology Aware Hints by setting the `service.kubernetes.io/topology-aware-hints` on a Service. This will not affect any Services without that annotation set. ([#108747](https://github.com/kubernetes/kubernetes/pull/108747), [@robscott](https://github.com/robscott))
