Just released, sIFR RC2. I just downloaded the new version to update a project. I have another in the works now that will really benefit from beautiful image-like headings. They've fixed some Opera quirks as well as the Flash URL limit.
Be sure to check it out. And if you haven't been following along and wonder what it's really about, you can view Danilo Celic's Breeze presentation about sIFR. He gave a nice visual guide to the process.
I'll type more later. For now, I've got a beach volleyball tournament to win.
