I replaced a 17-year-old Panasonic Inverter microwave oven with a new one. The firmware seems almost the same. The only differences I spotted:

1. "Quick min" (increment by 60 seconds) has become +30 (increment by 30 seconds)

2. When the microwave is done cooking, and starts beeping, the beeps stop immediately when the door is opened. The 17-year-old model rang out its beeps regardless of door state.
