I have not played it since the changes were made, so this observation is based strictly on the new aerial I see. I don't get the change to the fifth hole. It looks like the two big trees in the left part of the fairway are gone, and it looks like the fairway has been expanded. With the shape of the new green, it appears the best angle to attack it, especially to a back-right hole location, will be from the left side of the fairway, or away from the creek. So you may be awarded with the best angle when you choose not to negotiate the hazard.
I also see the stone wall around the eighteenth green was not re-shaped. Cosmetic to be sure, but it looked weird when I was standing in the fairway playing to the green. I wish that had been altered. Hopefully my next round there will allow me to better understand the change to the fifth.
