Joomla 3.7 is still in beta, so there is no way to know for sure. Most of the updates in 3.7 are in the backend, so there should be no issues though.
Joomla 4, is still in planning phases, and will not be released for a while. There is no way to say what compatibility issues there might be, if any.
