<p>
The new version number of a parameter. If you edit a parameter value, Parameter Store automatically creates a new
version and assigns this new version a unique ID. You can reference a parameter version ID in API operations or
in Systems Manager documents (SSM documents). By default, if you don't specify a specific version, the system
returns the latest parameter value when a parameter is called.
