Did they change the rotor design at some point in production? A friend of mine noticed some seem to have more slots than others.

Yes. Most of the slots are gone.

Do you know when they changed them?
Also why?

Probably why they changed from 2006-2007. Back then it was squeal. Now probably from the click noise complaints.

The first I remember hearing about it was MY19, maybe late 18.
I could see it being a small cost savings and the benefits of slots are negligible.

..... the benefits of slots are negligible.
Benefits of the slots are negligible as stated by @TrackDay

Also.... The risk of a heat-soak, micro crack is nearly guaranteed..... Which these turn into real cracks that may or may not be too deep to get rid of on a lathe.

Dodge isn't the only manufacturer changing their recommendation or brake spec.
