Really, did you get an L-type adapter? This would be great if Apple moved back to that style as I still have a few of those chargers laying around from my 2010 MBA.
The change to the original style is down to changing to the thinner magsafe 2. (compare it against your old power brick, the connector is longer and thinner.)
