If a DataStore reference has been versioned, `get_new_version_id()` will return the DataStore reference ID for the newest version. If the reference has not been versioned, the function returns NULL.
Arguments
- reference_id
Integer. A 7-digit number indicating the datastore reference to be queried.
- secure
Logical. Defaults to TRUE, indicating that the user is logged on to the NPS VPN (or is accessing the resource from an NPS office). Can be set to FALSE for non-NPS users. If `secure` is set to FALSE, `dev` is automatically set to FALSE.
- dev
Logical. Defaults to FALSE, indicating that the user wishes to work with the production version of DataStore. Can be set to TRUE if the user wants to work with the development environment on DataStore. Setting dev = TRUE will only work if the user has the appropriate permissions. Requires secure = TRUE.
