Hey all,

It seems QImage::setAlphaChannel
<https://doc.qt.io/qt-5/qimage.html#setAlphaChannel> was un-deprecated in
Qt 5.15
<https://forum.qt.io/topic/121460/qimage-setalphachannel-obsolete-or-not>,
but it's missing from the 5.15.2 wheels:

> > > from PyQt5 import QtCore, QtGui>>> i = QtGui.QImage("/tmp/front3.jpg")>>> m = \
> > > QtGui.QImage("/tmp/mask.png")>>> m = \
> > > m.convertToFormat(QtGui.QImage.Format_Alpha8)>>> i.setAlphaChannel(m)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'QImage' object has no attribute 'setAlphaChannel'>>>
QtCore.QT_VERSION_STR'5.15.2'>>> QtCore.PYQT_VERSION_STR'5.15.2'
