Some things seem to have moved automatically up to the toolbar. If that's happened, you'll now find them at the top-right of your window, between the search box and the burger menu.

I'm not sure what is supposed to happen with plug-ins that actually used the status bar for more comprehensive status information, such as the system you illustrated. You could check whether your (Burger)->Customize screen gives you anything you can dump on a toolbar somewhere as 'Osmose suggested, but since it appears you can only have one row of toolbar contents, the new model just seems to be broken for your purposes. :-(
