Anyone know if there will be a 4.9 version?
No, it won’t. We’ll have 4.8 updates (maybe then it will be called 4.9) and at the same time version 5.
I also don’t think that there will be a “big” jump in version 4.x…
Like Tech already said there should be small updates, but I don’t think it will reach 4.9…
But who knows…
