Hi all,

I'm just starting to use OpenCV again after a long hiatus. If I were to start a new project using a stable 2.4.x version, how hard would it be to transfer everything over to 3.x.x when it becomes stable? Will the 3.x.x versions be compatible with code written using the 2.4.x release? Would you just suggest using 3.0.0 straight away?

  • "Will the 3.x.x versions be compatible ?" - not really. devs there atm. dont seem afraid to break things large or small.

  • "how hard would it be to transfer everything over to 3.x.x ?" - not too hard. some constants/headers/libs to change. manual work. once 3.0 gets stable, there should be a well trodden path fror migration, too.

  • "Would you just suggest using 3.0.0 straight away?" - that totally depends on how daring you are (or curious about new functionality even). if you just want something stable to get back into opencv again, probably not.
