Release Notes: This is a development snapshot. Many icons have several versions (xxx-2.1.svg, xxx-2.2.svg, etc.) You should use the latest version. Existing open source SVG renders (KSVG, librsvg2/rsvg_display, xsvg, ImageMagick, etc.) can't render those icons. You need either Sodipodi-0.27 (or newer), or Adobe SVG viewer for Windows to render those icons. Rendering in ASV for Linux was not tested.
Release Notes: The BlueSphere icon theme now includes around 150 SVG icons pre-rendered in pixmap format for KDE.
