Looking here:

they appear to have a 3 month development cycle (assuming that the release of the notes match the release of the firmware) and so, following this logic, I would predict this will be mid-November. Why they cannot release bug fixes I do not know but I guess they must have their reasons??
If they do not fix these lock-ups, I have to say I will have just about run out of patience!
