3.1 simple actors documentation/tutorial?

Hi, I am excited by the prospect of high-performance simple actors in 3.1, but I've been unable to find any official documentation on them. The most basic question I have: are "simple actors" different from actors using the new "minimal" actor mode? Thanks to anyone who can explain a bit about this new feature and how it's specifically used.

They're the same thing.  Minimal actors have no physics but also can't use behaviors, so they must be controlled by other behaviors.

Thanks for clarifying that for me, Rob!
