A better analogy would be

Q. "How do I make my old model car do something (it cannot do)?"
A. "Get the free new model that has that feature added."

Of course, there is a cost to giving up the old and familiar and 
learning and adjusting to the new, even when it is available gratis. A 
husband wearing an old sweater after his wife gives him a new one, and 
even retrieving it from the trash when she tosses it out, is a classic 
(and true) cartoon joke.

But I am sure that 95% of readers here will be using 3.x withing 10 
years. The only question for them is "When?". This not-well-known new 
feature is one straw that some will put on the 'sooner' side of the balance.
