Not sure what this implies, though....
The PB guys seem to be adding new functions over time, but not removing any that I've noticed. So, any program built on slightly older versions of the SDK should still work, since the newer libraries still have the older functions in them. If a slightly older SDK has everything you need to build a program, then use it and it will work fine on even the latest firmware versions.
