One of the biggest changes users will notice right away is the new tabbed interface in CS4, but there are plenty of other time-saving features that will make this a worthy upgrade. Of the many application improvements, Photoshop seems to have gotten the most exciting ones, including true 64-bit compatibility and GPU acceleration to enable smoother panning and zooming.
Another new GPU-enabled feature is called Pixel Bender, which lets people apply special effects quickly and easily create their own. While Pixel Bender won't initially ship with CS4, it is promised to appear as an update through Adobe Labs soon. There are many more features worth checking out at Adobe’s web site and we’ll be sure to point you to the downloadable trials once they become available along with the full version sometime next month.
