Qt4-based backends
2+
~~~~~~~~~~~~~~~~~~
3+
The qt4agg and qt4cairo backends have been removed. Qt4 has reached its
4+
end-of-life in 2015 and there are no releases of either PyQt4 or PySide for
5+
recent versions of Python. Please use one of the Qt5 or Qt6 backends.
6+
7+
``qt_compat.is_pyqt5``
8+
~~~~~~~~~~~~~~~~~~~~~~
9+
This function has been removed due to the release of PyQt6. The Qt version can
10+
be checked using ``QtCore.qVersion()``.

``matplotlib.backends.qt_editor.formsubplottool``
13+
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
14+
This module has been removed. Use
15+
``matplotlib.backends.backend_qt5.SubplotToolQt`` instead.
