Can you elaborate on what has changed internally? Is the only change
that they depend on -Qt5 rather than -Qt wheels, and there, the Qt
installation is stored in a "Qt5" rather than "Qt" subfolder?

The reason I'm asking is that those wheels don't work properly with
PyInstaller anymore (either fails to package it outright, or fails to
find QtWebEngineProcess, or segfaults when creating the QApplication [on

It's probably an easy fix, but before I try, it'd be good to know what
actually changed.
