Thanks for your explanation, slembke!
If I am starting to build a game from nothing now, should I stick with the v6.x in Chipmunk Pro or the v7 on GitHub? It looks to me that I should take the v7 route since it's latest, however, as you have pointed out, the lack of documentation would likely burn me out...
Another question - I found that the v7 on Github has much fewer .h files exposed in the Objective-Chipmunk module, would features be limited compared to the v6 Pro version, or somehow a subset of features of v6?
If I get a v6.x license now, will there be a migration plan/procedure for ugprading to the future stable v7? or actually v7 is supposed to be backward compatible?
Thanks again for the great work, and spending time answering!!
