pyface doesn't support python3.9 and qt5?

[hitbuyi]

from setup.py, I found

so doesn't support python3.9 and qt5?

Thanks for noticing - we missed updating these on the last release.

Pyface (and TraitsUI) should work on 3.9 and 3.10 (and presumably 3.11 when it comes out), supports Qt5 via PySide2 and PyQt5, and it supports Qt6 via PySide6 (and may work with PyQt6 - changes to the way PyQt5 handles enums are more difficult to adapt to).

We are dropping support for Qt4

Edit: updated incorrect versions.
