Seems like the link attribute is indeed missing if you access the object through: context.scene.objects
However it is there if you go through collection.objects. If this was an intended change some of the default script files needs to be updated besides the rigidbody one.

In blender 2.8 you need to create an empty (type arrow) between 2 rigid body, because this empty will be the link ( the constraint) between this 2 rigid body. after select the empty and go to physic tab and select "rigid body constraint" ! Then select object one and two !

How can you chain objects if you need to select first and second object?

I really hope that this will be fixed at some point, or how else would one try to connect 75 Rigid Body Tank track links?

@Archimondro I agree, I had to go back to V2.79 because I could not complete the task I needed to do. I was doing rope simulation and need rigid body for that and need to chain them. At the moment that is impossible in V2.80 beta, unless I work a few hours on it instead of a few minute.

For rope simulation go to my youtube chanel : nadagalou
I have made lot of tutorial to create physic rope. But it's true for 75 ridgid body tank track it's very difficult in 2.8.
