- Client-go: fake client-go (i.e. anything using k8s.io/client-go/testing) now supports separate List+Watch calls  with checking of ResourceVersion in the Watch call. This closes a race condition where creating an object directly after an informer cache has synced (= List call completed) and before the Watch call completed would cause that object to not be sent to the informer. A visible side-effect of adding that support is that List meta data contains a ResourceVersion...
