You'll get a release when it has been tested enough to resolve issues. I know they promised 9.0.3 in about a week, it didn't happen. Why yours is crashing on exit? No idea because you don't post any details about your configuration (OS, Memory amount, HDD/SSD size/speed, etc). Perhaps if you post some specs of your system (desktop/laptop), any MIDI controllers/Hardware in the mix (USB, Firewire, etc...), audio interface, MIDI interface et al, someone may be able to help you out.
Complaining won't get you anywhere other than tired, frustrated, more pissed off. Quit the complaining and let the developers and beta testers do their work to get an update out. Who knows how long before an update will come out now? I have no idea, I am not in a rush for it, unlike some others.
Yes how dare you want a stable program without any effort on your part, it's not like you paid for ....wait..
