I upgraded via the convenient Help|Look for updates from 1.5 beta2.
It was a 600KB+ download.
If you are attached to any extention, be prepared to find that it is not compatible.
rc1 is good, so far. It only got twisted around itself checking for extention compatibility. I had to click Cancel. It was fine after that.
