have addons include a "WORKING_WITH_OF" #define

Could be a really nice way to help people know which version something works with.

Not a bad idea. Does OF store its version umber somewhere in the code? if it does we could also prepare some sort of #define function that would trigger a compile warning when it doesn’t mach up with the current of version…

yes, there’s an OF_VERSION define and since some months ago a OF_VERSION_MINOR so 007 will be

OF_VERSION 7
OF_VERSION_MINOR 0

0071

OF_VERSION 7
OF_VERSION_MINOR 1

and yeah seems a good idea
