I guess thats the same reason why you ignored the first part of my question? :p I get that it doesnt always goes like planned (better then i would like to) and i appreciate your honesty about it. I wont nail you down on your estimate and i think every reasonable person can deal with some delays as long as we roughly understand the reasons causing this. So yeah.. keep up the revived communication!
There isn't much to add from my previous post saying that the fixes are aimed at the stability (crashes) and performance (stuttering) issues.
