Go to Help -> Adding Qt Versions
The way to add new Qt versions has changed since the options dialog has changed.
Go to Help -> Adding Tool Chains
The way to add new Tool chains has changed since the options dialog has changed.

=> for both there is now a single tab (Build & Run) and you can switch there to Qt Versions or Tool Chains
