Unfortunately, this still prevents me from testing my project against
Qt 6.4, which is now at Beta 2.

Wasn't there a tool at some point which would let me take the current
PyQt6 wheels and replace the Qt install by a newer one? I guess that
would work then, and I'm pretty sure I used it before. But now, I can't
find a trace of it in the PyQt5 or PyQt6 docs. What am I missing?

Thanks,
Florian
