Fairly sure why the july 3rd doesn't have too many things is that ED probably stopped accepting changes a while ago (they were initially planning an update this week)
Also the MMS display bug (if it's the one I'm thinking of) they've said is something ED must fix.
You can send target points and messages to other Kiowas, but at least in DCS you can't send to Apaches. So you're stuck with voice there.
(Also, currently attempting to store a received target will crash to desktop, so that's a no-go until fixed)
