From Frederik this morning "Dear Ultra Fractal users, I am very pleased to announce the release of Ultra Fractal 4! It is available right now at www.ultrafractal.com. New features include full animation support, a new Explore feature that makes it much easier to find new parameter values, the ability to render flame fractals, improved formula compiler and calculation engine, a new syntax-highlighting formula editor, and more. To see a complete list of the new features, download a copy and open the What's New chapter in the help file. Ultra Fractal 4 is available in two editions: the Animation Edition and the Standard Edition. The difference is that the Standard Edition does not support animations and network calculations. Ultra Fractal 4 Animation Edition costs US $129, and US $69 for an upgrade from any earlier version of Ultra Fractal. The Standard Edition costs US$59, and US $39 for an upgrade. You can upgrade from the Standard Edition to the Animation Edition for US $79. See www.ultrafractal.com/editions.html for more information. Sincerely, Frederik Slijkerman. www.ultrafractal.com info@ultrafractal.com"
