What happened?

Ive had this game since August 2011, back when it was first released. The last update to the game was version 2.6. Now this game is re-posted as version 2.7 as a new game, and the original one is removed off the store? Now this new 2.7 version is the primary one that is being updated... Even if I buy it again, my saved game data cannot be merged together... So what gives? What happened and what was the point of this??
