I don't think that's right. Didn't several generations of 737 before MAX have that flattened engine bottom? I think I've been seeing it for considerably longer than MAX has been around.

Ah, yes, searching a bit, you appear to be right about the flat bottom. I believe the sawtooth edge is still correct though.

The sawtooth is called a "chevron" and is designed to reduce engine noise to meet FAA standards.
