  * You can find the PodSpec tolerations that were created as annotations (if any) in a controller definition by doing `kubectl get <controller kind> <controller name> -o yaml` and looking for the "Annotation" section with the annotation key `scheduler.alpha.kubernetes.io/tolerations` (This will work whether you are running Kubernetes 1.5 or 1.6).

- Add scheduling support for RuntimeClasses. RuntimeClasses can now specify nodeSelector constraints & tolerations, which are merged into the PodSpec for pods using that RuntimeClass. ([#80825](https://github.com/kubernetes/kubernetes/pull/80825), [@tallclair](https://github.com/tallclair))

- `PodSchedulingReadiness` is graduated to beta. ([#115815](https://github.com/kubernetes/kubernetes/pull/115815), [@Huang-Wei](https://github.com/Huang-Wei))
- `PodSpec.Container.Resources` became mutable for CPU and memory resource types.
  - `PodSpec.Container.ResizePolicy` (new object) gives users control over how their containers are resized.
  - `PodStatus.Resize` status describes the state of a requested Pod resize.

* Adds BETA support for `DNSConfig` field in PodSpec and `DNSPolicy=None`, so configurable pod resolve.conf is now enabled by default. ([#59771](https://github.com/kubernetes/kubernetes/pull/59771), [@MrHohn](https://github.com/MrHohn))

`AffinityInAnnotations=true` in `--feature-gates`, then the 1.7 release is your last opportunity to convert from specifying affinity/anti-affinity using the scheduler.alpha.kubernetes.io/affinity annotation on Pods, to using the Affinity field of PodSpec. Support for the alpha version of node and pod affinity (which uses the scheduler.alpha.kubernetes.io/affinity annotations on Pods) is going away **in Kubernetes 1.8** (not this release, but the next release). If you have not enabled AffinityInAnnotations=true...

- Updated to use golang 1.12 ([#74632](https://github.com/kubernetes/kubernetes/pull/74632), [@cblecker](https://github.com/cblecker))
- The `RunAsGroup` feature has been promoted to beta and enabled by default. `PodSpec` and `PodSecurityPolicy` objects can be used to control the primary GID of containers on supported container runtimes. ([#73007](https://github.com/kubernetes/kubernetes/pull/73007), [@krmayankk](https://github.com/krmayankk))

### API Change

- Add `NodeInclusionPolicy` to `TopologySpreadConstraints` in PodSpec. ([#108492](https://github.com/kubernetes/kubernetes/pull/108492), [@kerthcet](https://github.com/kerthcet))

- Removed note that `hostAliases` are not supported on hostNetwork Pods from the PodSpec API. The feature has been supported since v1.8. ([#122422](https://github.com/kubernetes/kubernetes/pull/122422), [@neolit123](https://github.com/neolit123))
