- klog has been updated to 0.3.0 ([#76474](https://github.com/kubernetes/kubernetes/pull/76474))
- k8s-dns-node-cache image has been updated to v1.15.1 ([#76640](https://github.com/kubernetes/kubernetes/pull/76640), [@george-angel](https://github.com/george-angel))

### Unchanged

- The kubelet now creates an iptables chain named `KUBE-IPTABLES-HINT` in
  the `mangle` table. Containerized components that need to modify iptables
  rules in the host network namespace can use the existence of this chain
  to more-reliably determine whether the system is using iptables-legacy or

    strings to indices.
*   Support restore session from checkpoint files in v2 in
    `contrib/session_bundle`.
*   Added a tf.contrib.image.rotate function for arbitrary angles.
*   Added `tf.contrib.framework.filter_variables` as a convenience function to
    filter lists of variables based on regular expressions.
*   `make_template()` takes an optional `custom_getter_ param`.
