Anyone know why the fuel pump relay part was changed by Suzuki?

Just curious as have some suspicion of mine causing fried ECU's. Maybe they switched to a type that includes a voltage supression diode/resistor/capacitor to help protect the ECU or does the ECU have this supression built into it? Or,maybe its just the manufacturer obsoleted the old part number and this is its replacement and essentially the same? It looks like this changed for all year models too.
