I'm truly sorry that this is dragging on longer than I ever expected. Am I frustrated? Yes.
Just before the runtime was to be released a critical bug in setup was found that caused setup to not install on random machines. Multiple attempts to fix the issue failed but we are hopeful the last one will do the trick. A build kicked off today--best case is it will take a week to verify the fix, run the final test pass, and get something on the web. If we a recall bug comes up--we can't in good consciousness release the runtime and the clock will start over.
Once again, sorry for the inconvience this has caused.
