I am rarely, if at all, using the features that you guys are reporting as broken. From my perspective, 0.99.42 appears stable enough. See, everyone among us uses Construct differently, most of us barely touch features you use extensively, so our experience is going to be different.
Notice that mostly reported issues get fixed. Ergo, if you want a stable build, report issues you encounter, they will get fixed eventually. Don't just count on someone else doing it for you.
