PyQt6

PyQt6 is provided as a source distribution (sdist) and binary wheels from PyPI. The wheels include copies of the corresponding Qt libraries. To install it run:

pip install PyQt6

PyQt6 introduces the following incompatibilities with PyQt5:

• All enums are now implemented as enum.Enum (PyQt5 used enum.IntEnum for scoped enums and a custom type for traditional named enums). PyQt5 allowed an int whenever an enum was expected but PyQt6 requires the correct type.
• QFlags are implemented as enum.Flag.
• Q_CLASSINFO has been replaced by the pyqtClassInfo class decorator.
• Q_ENUM and Q_FLAG have been replaced by the pyqtEnum enum decorator.
• Q_ENUMS and Q_FLAGS have been removed.
• All exec_() methods have been removed.
• All print_() methods have been removed.
• The Qt module has been removed.
• QtWidgets.qApp has been removed.
• The QtCore.PYQT_CONFIGURATION dict has been removed.
• pylupdate can no longer read a .pro file in order to determine the names of .py files to translate.
• pyrcc has been removed.
• Python v3.6.1 or later is required.

Below are any snapshots of the next release of PyQt6 including all bug fixes.
