4.18.0 Release - iOS icons and Marketing Image

There has always(?) been an 83.5@2x, which is the 167x167 for the iPad Pro Retina iOS9… I don’t see that that changed over at Apple, but maybe I am missing it. Up above I listed what I thought were the icon sizes to use and that is why I was a little confused on the new naming of the required icons. Any clarity on that would be appreciated from anyone who knows! Thanks!
