Version History

06-18-2009 PhiMatrix 1.618 Released

• Completely reprogrammed in a cross-platform environment to run on XP, Vista and Mac OS X.
• Free floating grid with no application border to obstruct images or other applications.
• Greatly improved user interface with many new features.

Note:  Why the jump from 1.1 to 1.618?  Because this is a major new release and, like the ratio of Fibonacci series numbers converging on phi, the goal for Phimatrix is to get closer and closer to a point of perfection, not to just increase the version number.
