That is a bit confusing then. If I understand correctly, depending on which installation you have. For example the official release or unstable or stable then there can be different versions of the bindings? And you kinda have to know where to get the right version you are looking for?
Maybe I’m overcomplicating it. hmm. 
I’m using unstable version. I think.
This is what I put in my sources list when we did that update thing going back a week or two.
My karaf says this:
Does that mean I can simply update the binding via the easy way in paper ui? Otherwise I’ll need to research more about this other way that you mention in your posts above, that about kinda moving files putting stuff manually in the addons folder etc.
