Backward compatibility of Flask_Tryton

Hello everybody. I am currently writing a FHIR API for GNU Health (runs on Tryton). For that I am using Flask_Tryton. I was wondering about the Backward compatibility of Flask_Tryton. What happens when there is a new Version of Tryton? Would I also have to update Flask_Tryton? Or are both Projects independent from each other and a change in Tryton would not (usually) break Flask_Tryton?

And does anybody know what the oldest supported Version of Tryton is for the current Flask_Tryton Version (0.11.2).

Thanks in advance!

flask-tryton is a contrib so it does not follow the official Tryton schema of release.
It is written to be compatible with as much possible version of Tryton.
The defines which version of trytond are compatible.
