Exporting and Synchronising in vCard 4 for LinPhone

[plittlefield]

I am using the Docker image with version 0.8.0 running happily and tested with Mozilla Thunderbird address book.

I would like to try synchroning with LinPhone

How do I change the vCard version from 3 to 4 ?

I could not see a way in the Baikal 0.8.0 Web Admin.
