In the Official release: New cards, None working cards removed, Story mode added but it's just a "teaser" really to push softcoders to create campaigns and give them a general idea, New graphics on startup (random), various bug fixes and enhancements. Don't have the exact changelog by hand but this is about it. And btw this isen't a discussion it's an announcement for the public beta, not the latest official release.
