I've stopped commiting in the last 2 months hoping people will become aware of the problem and will do something to improve it. With the exception of 50D, there was no real progress in merging back the code from TL; they keep moving away from the main line, they take all the cool stuff from ML without giving anything back, and I can't solve it alone.
I don't want to dictate what others should do, so I'll only decide what I should do. I just can't continue like that, sorry.
