The Sitefinity 12.1.7100 version comes by default with Jquery 1.12.1 and a Jquery version update is required. question: Until which version is it possible to update Jquery successfully?, What are the best practices for making these types of updates?

I have tried to make changes in Sitefinity BackEnd mode, but without good results since it always loads the default version, regardless of the changes I make. The main target is to be able to update jquery version for Sitefinity 12.1.7100. the optimal, obviously.
