I'm pleased they rename it because grid-lanes opens up more than masonry layouts.

I've been waiting to be able to have a fully responsive layout (where interleave sidebar content in with the page content on small screens, but have it in a sidebar on larger screens) without using any JavaScript, and this finally makes it possible.
