[PyQt] implications of running PyQt 4.4.x with Qt 4.5?

[Devon Rueckner]

Hi -

We would like to upgrade to Qt 4.5 for its bug fixes, performance and license.

After simply swapping out Qt and leaving PyQt alone, empirically
everything works with the exception of a few graphics view rendering
issues.

Is running PyQt 4.4.4 with Qt 4.5 considered supported?  What are the
implications?

Thank you,
Devon
