* The generic RESTClient type (`k8s.io/client-go/rest`) no longer exposes `LabelSelectorParam` or `FieldSelectorParam` methods - use `VersionedParams` with `metav1.ListOptions` instead.  The `UintParam` method has been removed.  The `timeout` parameter will no longer cause an error when using `Param()`.
