Version 0.46 of the open-source vector application has been released, and it has a pretty strong set of new features. I've used this program a fair deal myself, and I have to say that this update (or application in general) is a must-have. Do take your time to download and experience inkscape for the first time if you haven't used it before, or enjoy the new features if you're a more experienced user.
Quote from inkscape.org:
The Inkscape community today is announcing the release of the newest version of its open source vector graphics editor. Inkscape 0.46 is a major update that introduces native PDF support. The implementation of PDF support in Inkscape provides an easy, open source solution to editing PDF documents.
Tons of new features and performance improvements are included in this release. Dialogs now have the ability to be docked to the editing window. Gradients can be edited completely on-canvas. The new Paint Bucket Tool fills bounded areas with color. A new 3D Box tool helps create perspective-correct drawings. A new Tweak tool provides an intuitive method for editing paths and painting objects. The new Live Path Effects feature can create "brushes" and various organic effects on paths. Improvements to color management include support for color spaces other than sRGB. Most SVG filters are now implemented, and a new powerful UI is provided for editing filter stacks.
