migrations of those stuff in v2?

Not sure about getLastFrameRate, but for zoom, see this post from Andrew:

zoom not a member of rack::settings ?

You can get the RackScrollWidget's zoom level with APP->scene->rackScroll->getZoom() and a similar setter. Zoom levels are linear, not exponential like settings::zoom. Another purpose of zoom I’ve seen plugins use is conditional drawing of fine details to save CPU. For that, plugins should read the NanoVG state in draw() such as float t[6]; nvgCurrentTransform(args.vg, t); float zoom = t[3];
