This is a major release with significant enhancements over the 0.2.x series. Navigations icons (Back, Forward, Up, Down, Stop) were reworked to get better rendering at 16x16 and 22x22. Desktop and Home icons have new colors and new design. A Cut icon has been added to give Copy/Cut/Paste operations a consistant look. Rendering has been added for 64x64 and 96x96 sizes (apps, filesystems, and MIME type).
