     * The previous version, <code>apiVersion: extensions/v1beta1</code>, is still supported.  Even if you roll back to 1.1, the objects created using
the new apiVersion will still be accessible, using the old version.   You can
continue to use your existing JSON and YAML files until you are ready to switch
to <code>batch/v1</code>.  We may remove support for Jobs with  <code>apiVersion: extensions/v1beta1 </code>in 1.3 or 1.4.
