When the Template View loads a template it checks for subtemplate instances and determines if there are newer versions available. Any "Out of Date"
subtemplates are highlighted the Subtemplates tab. Any updated subtemplates are flagged as "Up to Date".
Click on Save to save the updated subtemplates.
NOTE: When a template is deployed, it always uses the latest version of any contained subtemplates found on the client
Workbench even if the parent template has not upgraded its subtemplates. If a template has been modified to add additional Inputs,
Outputs, Relations, or Configuration properties, it would be important to review any templates that use the modified template
to resolve the new I/Os within the parent template.
