Yeah we have experienced problems with git (our version control system).
Before each update we spend a couple of days testing. But with so many features it's not possible to find every glitch, on every device. We're pretty quick at fixing bugs though. Its important customers report them to us so we can fix it asap.
Please note we are pushing out bug fixes on a daily basis.
I'd feel bad if you left because of these bugs, but I completely understand where you're coming from. This is why I switched from Windows to Mac. We'll try to test a little longer in the future.
