You can use it but as I have posted earlier there are issues with some of the skins. QT has not come up with fixes yet and may guess is they will not try to fix it for 4.5.0 at all but wait until 4.5.1 is out and make it work there. Since 4.5.1 is taking so much time (compare to before) to be released they may even release it with Smarty 3 included but who knows...
