OpenCV 2.4.8, that can't still be so!

I was trying to use some newer features of OpenCV, but I discovered it’s still using version 2.4.8, when the last version of that branch was 2.4.13.6.

Obviously I think it should be using 4.7.x, as this would enable us to be more creative with some experimental plugins. Object detection and image classification using DNN.
