- Kubernetes is now built with golang 1.15.0-rc.1.

* kubelets are no longer allowed to delete their own Node API object. Prior to 1.11, in rare circumstances related to cloudprovider node ID changes, kubelets would attempt to delete/recreate their Node object at startup. If a legacy kubelet encounters this situation, a cluster admin can remove the Node object: `kubectl delete node/<nodeName>` ([#62818](https://github.com/kubernetes/kubernetes/pull/62818), [@mikedanese](https://github.com/mikedanese))...

        then:
        format(link) == '<someLinkElement/>'

        where:
        input << [
                '#someName(SomeClass,Object)',
                '#someName(SomeClass, Object)',
                '#someName(SomeClass,\tObject)',
                '#someName  (  \t SomeClass ,\tObject\t ) '
        ]
    }

  - A namespaced object with an ownerReference referencing a uid of a namespaced kind which does not exist in the same namespace is now consistently treated as though that owner does not exist, and the child object is deleted.

        The new optimizer's `learning_rate` property returns the
        current learning rate value instead of a `LearningRateSchedule` object
        as before. If you need to access the `LearningRateSchedule` object,
        please use `optimizer._learning_rate`.
    *   **You implemented a custom optimizer based on the old optimizer.**
        Please set your optimizer to subclass
