support the alpha `scheduler.alpha.kubernetes.io/affinity` annotation on the Pod if you explicitly enable the alpha feature "AffinityInAnnotations", but it will be removed in a future release. When you upgrade to 1.6, if you have not enabled the alpha feature, then the scheduler will use the `affinity` field in PodSpec and will ignore the annotation. If you have enabled the alpha feature, then the scheduler will use the `affinity` field in PodSpec if it is present, and otherwise will use the annotation....

    * validation schemata as an alpha feature, to be enabled via the "CustomResourcePublishOpenAPI" feature gate. Kubectl will validate client-side using those. Note that in
    * future, client-side validation in 1.14 kubectl against a 1.15 cluster will reject
    * unknown fields for CRDs with validation schema defined. 

* Pod priority can be specified ins PodSpec even when the feature is disabled, but it will be effective only when the feature is enabled. ([#59291](https://github.com/kubernetes/kubernetes/pull/59291), [@bsalamat](https://github.com/bsalamat))
