The professional version allows you to send me as many support questions of feature requests as you like without feeling like a cheapskate. And it encourages me to answer your questions more quickly and in more detail, and consider your feature requests more seriously. You also help to ensure that future development ont he system will continue. I can't keep working on it full time for free! :-)
Beyond that, you gain the right to publish your game in stores.
And that's about it! There's only one version of the code itself.
Btw, the current non-public release version of the sprite system is 117. The latest changes include tying the physics update code to the regular animaton update code to make it easier to just use the physics at any time with no special setup. If you're just getting the system you might want to request this version, but none of the demos have been updated to use it. It does have information on how to convert old code to use the new setup though. Few function calls have changed and the main loop needs a little rearranging on the functions. Shoudn't affect anyone's projects beyond that.
