What version of Revit does AutodeskForge support?

When converting the file created by Revit 2014 to SVF, the following error occurred:

The file was saved in an old version of Revit which we don’t support. Please upgrade this project to Revit {0} or later.

I found out that the Revit version is old. I don’t know the scope of Revit version that AutodeskForge supports. What is the problem if Revit 2016 and above?

Best to ask this forge question in the platform designed for Autodesk Forge questions. This is for Dynamo and while there is a lot of overlap, you’ll likely have better luck there.
