ue4 4.20 c++ plugin migration help

4.20 references plugins differently but someone somehow forgot to let everyone know how to migrate their plugins. The information that I did find was incomplete and not at all helpful. Can someone please explain in detail how to properly migrate a plugin from 4.19 to 4.20 please?

I don’t even know if it’s plugin or project migration that I need. This is outrageous. How on earth do you put out an update like this without giving the proper documentation?

After doing a lot more searching, it seems that this is a bug from july that hasn’t been fixed yet? I have no idea any more. Maybe I put too much trust in this engine. I’m burnt out from not finding up to date documentation or not finding any information or documentation at all. I’m not sure which is worse.
