This was my interview question today sam, I was wondering about the question too, trying to get some answers from EDA communityVery vague question. The composition of a standard cell library has some relationship with the node, but it is not that strong. All the basic logic cells will be there, FFs, INVs, NANDs, NORs, etc. There are some physical only cells that might be new due to padding reasons/doping restrictions. But then again, who knows what you are asking.
