- Server Side Apply now treats LabelSelector fields as atomic (meaning the entire selector is managed by a single writer and updated together), since they contain interrelated and inseparable fields that do not merge in intuitive ways.

*   Tensorflow code now produces 2 different pip packages: `tensorflow_core`
    containing all the code (in the future it will contain only the private
    implementation) and `tensorflow` which is a virtual pip package doing
    forwarding to `tensorflow_core` (and in the future will contain only the
    public API of tensorflow). We don't expect this to be breaking, unless you
    were importing directly from the implementation.

mechanism to beta, adding alpha support for a new CSI driver registry as well as for topology, and adding a number of alpha features to support the use of CSI for “local ephemeral volumes” (that is, volumes that exist for the lifecycle of a pod and contain some injected information, like a token or secret).

With Kubernetes v1.12, SIG Storage also introduced alpha support for [volume snapshotting](https://github.com/kubernetes/enhancements/issues/177). This feature introduces the ability...
