affinity/anti-affinity allow you to specify rules for restricting which node(s) a pod can schedule onto, based on the labels on the node. Pod affinity/anti-affinity allow you to specify rules for spreading and packing pods relative to one another, across arbitrary topologies (node, zone, etc.) These affinity rules are now be specified in a new-in-1.6 `affinity` field of the PodSpec. Kubernetes 1.6 continues to support the alpha `scheduler.alpha.kubernetes.io/affinity` annotation on the Pod if you explicitly...

- Kubelet: Closed a loophole that allowed static Pods to reference arbitrary ResourceClaims. Even though these Pods failed to run due to a sanity check, such references are now explicitly disallowed.

- Kubelet: close a loophole where static pods could reference arbitrary ResourceClaims. The pods created by the kubelet then don't run due to a sanity check, but such references shouldn't be allowed regardless.

* the test/e2e/e2e.test binary can test arbitrary storage drivers, see the `-storage.testdriver` parameter ([#72836](https://github.com/kubernetes/kubernetes/pull/72836), [@pohly](https://github.com/pohly))

- Added GenericPVCDataSource feature gate to enable using arbitrary custom resources as the data source for a PVC. ([#88636](https://github.com/kubernetes/kubernetes/pull/88636), [@bswartz](https://github.com/bswartz)) [SIG Apps and Storage]

- Added a feature that allows a `StatefulSet` to start numbering replicas from an arbitrary non-negative ordinal, using the `.spec.ordinals.start` field. ([#112744](https://github.com/kubernetes/kubernetes/pull/112744), [@pwschuurman](https://github.com/pwschuurman))
