GPL v3 Licence restrictions


I am interested in the further development of tryton OS ERP system but i would know if there are any limitations or restrictions according to the GPL v3 Licence.

Kind regards

The limitations or restrictions are explicitly written in the license. You can find some explanation on A Quick Guide to GPLv3 - GNU Project - Free Software Foundation
If you want to know the implications for your use case, I would suggest to take advise from your lawyer.
