Looks like we can now test the click delay fixes (which should match chromium).
Touchpad pinch-zoom (and rotation) exposed in Safari using their proprietary gesture event API. I told them we'd be interested in collaborating on a standard API for this scenario, but that we didn't plan to push something without their support. Oh well, not super important IMHO.
Also a change to viewport behavior (with a new "shrink-to-fit" keyword) for windowed modes.
