Yes, 32bit support and you can never go back. I think it is really bad to "upgrade" to a major OS version every year and potentially cut off all bondings some artificial unknown time (days, months...) later.It is still OS 10, right. Every followup is just a revision, it must not break compatibility. That was the rule before. Nowadays they push an update and two years later none of your Apps are working anymore, maybe sooner, who knows?
