Yes just a few days ago we did mentioned that June’s Xbox One system software update would be made available to preview members in two waves like normal. although most people we know on our group had it!
If you’re a preview member and didn’t make the cut in the first wave, it’s time to check out your console, because Program Manager Emily Hanson announced in the private preview forums that the second wave has now been released, and everyone is now included. Yay! ?
If your console is in Instant-On mode, the update will download and install automatically when on stand-by, otherwise you can download it manually in Settings -> System -> System Update. If you want to make sure you have it, the OS version (in Settings -> System ->Console Info) is xb_rel_1506.150519-2200.
