Unfortunately you brought this up just after I installed 4.7-1 on the
build machine. I do have Py2.5-gpl-4.4.3 around. (Also, after installing
PyQt 4.7, QtCore.qVersion() reports '4.6.1', and
hex(QtCore.PYQT_VERSION) is '0x40700'.)

Riverbank certainly makes it harder than it could be, because they only
keep 1 file for download for any given version of Python. I would like
us to target the same version for Windows 2.1 as the PyQt version that
will be in Lucid. That way we should end up with a standard PyQt version
for the stable series. I'd go far enough to say that we could keep
PyQt4.7 w/ Python2.5 for all of the 2.1 series installers, and then
upgrade to 2.6 + whatever new PyQt for the 2.2 series.

(The main reason is that it would be a real pain to try to target 2
versions of PyQt w/ the same version of Python.)
