    *   Make crictl command more user friendly and add more subcommands.
    *   Integrate with CRI verbose option to provide extra debug information.

	// If WriteHeader is not called explicitly, the first call to Write
	// will trigger an implicit WriteHeader(http.StatusOK).
	// Thus explicit calls to WriteHeader are mainly used to
	// send error codes or 1xx informational responses.

	// The provided code must be a valid HTTP 1xx-5xx status code.
	// Any number of 1xx headers may be written, followed by at most

### SIG-ibmcloud

As a newly created SIG, the SIG-ibmcloud has mainly focused on SIG set up, sharing IBM Clouds ongoing Kubernetes work like scalability tests, Kubernetes upgrade strategy etc. with the SIG members and start working on processes to move cloud provider code to a public GitHub repo.

### Node

* Summary of Container Runtime changes:
  * [beta] [cri-tools](https://github.com/kubernetes-incubator/cri-tools): CLI and validation tools for CRI is now v1.0.0-beta.0. This release mainly focused on UX improvements. [@feiskyer]

## Major Themes

### SIG API Machinery

Returns the timestamp as a `float64` for seconds since the Unix epoch.

Common usages include:
* Logging
* Providing a random number seed
* Debugging graph execution
* Generating timing information, mainly through comparison of timestamps

Note: In graph mode, the timestamp is computed when the op is executed,
not when it is added to the graph.  In eager mode, the timestamp is computed
when the op is eagerly executed.
