Does anyone remember the new blending modes that were teased for 2.2?

I was about to post how awhile ago, someone mentioned rob was adding different blending modes (e.g. darken, multiply, screen, negative) but now I can’t find a single bit of info on it. Does anyone else remember this or did I just hear something wrong?

Also, the addition of blending modes seems small on the surface, but if you’re into digital art, this could be HUGE.
