Hi Łukasz,
I’m sorry you found the projects difficult to work with. It sounds like in
this case it was about modularizing with Maven and making TinkerPop work better

Is there consensus on a way forward with this? Is there going to be a three
branch plan with “features”, “testing”, and “stable” starting with 4.0? Or is
this still in the discussion mode? External to this thread there have been
