The only differences may be: that the point counts for foods have changed, the number of daily points you get and the zero point foods (green - 100 zero pts - only fruits and most vegs; blue - 200 zeros- all fruits and vegs, chicken/turkey breast, all fish/seafood; and purple - 300 zeros - blue + 100 more - whole grains, some whole wheat product, rice, popcorn, quinoa etc)
