I've noticed that on new aircraft, the pax windows seem to be more oval-shaped than on older aircraft. FOr example, the windows on a 764 or 772 are more rounded than the windows on say a 744 or older 762 or 763. Why is this? What sparked the windows to be rounded off? I first noticed this on the Airbus A319/320 series for what it matters...

Areopagus is correct. Square windows have pressure points i.e. one in each corner. Round or oval windows distribute the pressure equally around the window. You see the same idea in arches. An arch carries the weight evenly throughout the structure.
