There has been a lot of fiddling but the SVG handling is much smoother and safer than after the initial intro. I'm testing by uploading the svg files directly into a post which you can do now. A lot of svg's display just fine. There have been a few parsing issues --- we'll just have to work through them. We still don't handle every svg tag, but we should have most of the important ones.
Gradients still seem to have conversion issues.
