  - OS and Arch information is now recorded in `kubernetes.io/os` and `kubernetes.io/arch` labels on Node objects. The previous labels (`beta.kubernetes.io/os` and `beta.kubernetes.io/arch`) are still recorded, but are deprecated and targeted for removal in v1.18.

Fixed the bug where `spec.terminationGracePeriodSeconds` of the pod will always be overwritten by the MaxPodGracePeriodSeconds of the soft eviction, you can enable the `AllowOverwriteTerminationGracePeriodSeconds` feature gate, which will restore the previous behavior.  If you do need to set this, please file an issue with the Kubernetes project to help contributors understand why you needed it.

Omitting the list of expressions is therefore equivalent to
repeating the previous list.  The number of identifiers must be equal
to the number of expressions in the previous list.
