@SašoŽivanović Nothing you do right now will have much effect on most users anyway as TeX Live is now frozen. So Forest in TL 2015 is 2.0.2 forever, but the 2.0.3 version is available on CTAN, of course. (Presumably MikTeX will pick it up, too.) If possible, I would like to ensure that when TL 2016 is created it uses a version of prooftrees which works with whatever version of forest it includes. Do you think it might be possible for us to coordinate sufficiently to ensure this?

@cfr I had no idea about the freeze. Where is it announced when it will be frozen? And yes, it would be good to coordinate, sorry I was too slow this time.
