No difference with PyQt6-6.1.0.dev2104161239 unfortunately:

  Looking in indexes: https://www.riverbankcomputing.com/pypi/simple/

    Downloading https://www.riverbankcomputing.com/pypi/packages/PyQt6/PyQt6-6.1.0.dev2104161239-cp36.cp37.cp38.cp39-abi3-manylinux_2_28_x86_64.whl (6.7 MB)
       |████████████████████████████████| 6.7 MB 1.6 MB/s
  ERROR: Could not find a version that satisfies the requirement PyQt6-Qt6>=6.1
  ERROR: No matching distribution found for PyQt6-Qt6>=6.1

(Also, it looks like the beta Qt wheel vanished from
https://riverbankcomputing.com/pypi/simple/pyqt6/ again?)
