Scrolling zooming

so the scolling zoom for mouse an trackpad seems to be missing from the latest update… is the correct or am i missing something?? this is a terrible loss of functionality…

I´m on a Trackpad on OS X 10.10.3 (Yosemite Beta)

I get this:
“Orbit” on scroll,
“Pan” on [SHIFT] - scroll, and
"Zoom" on [CMD] - scroll.

Nothing there?
