Magic Keyboard 2024 new features?

I spilled coffee over my previous keyboard so replaced it over the weekend with the USB-C version thinking only the port had changed. I noticed after hitting the control key multiple times the keyboard has now 4 keys next to the spacebar. There is now an emoji button. I also noticed they changed the previous emoji key to a contextual key.

So I wanted to see what other changes they made but most articles just mention it's unchanged besides the USB-C port.

What else changed? Did they make the keyboard coffee resistant already?
