The required_interactive_framework attribute of backend modules introduced in Matplotlib 3.0 has been moved to the FigureCanvas class, in order to let it be inherited by third-party canvas subclasses and to make it easier to know what interactive framework is required by a canvas class.

backend_qt4.FigureCanvasQT5, which is an alias for backend_qt5.FigureCanvasQT (but only exists under that name in backend_qt4), has been removed.
