Yes. I don't think that's workable, at least not with a time-based release schedule that people believe in. I can't see how they will avoid adding API in stable releases too. So in the end, I don't see how much will change, other than that we will now have uncertainty about what and when things should, and will, happen. I'm not a fan, clearly. It looks like people have got so used to having time-based releases that they forgot why they need them - a bit like thinking that diseases aren't serious because we are used to having vaccinations. But I'm also not heavily involved, so my opinion shouldn't count for much. > This is supposedly firstly to allow for a higher rate of > innovation (official breakage), and secondly to reduce the amount of > unofficial breakage between ostensibly stable and compatible > releases, Of course, the answer to that would be just to document things properly. > which has caused problems with the 3.* series.
