Where is blandables array in 4.15?

So I’m trying to make an outline for my objects but I simply can’t find a blandables array. It used to be in postprocessing volume settings but I do not see it there in 4.15. Where is it now?

Its now listed as Post Process Materials → Array, click on your post process volume and type “materials” in the search and it will pull up the Post Process Materials in the details panel and just click on the arrow to open it up and you’ll see Array.
