Microsoft have released a small update for June to Preview Members today which fixes a few minor issues. We expect the new Xbox One Dashboard update to be released soon, so it makes sense that Microsoft won’t release a big update until then.
The change log for the update as follows:
OS version released: xb_rel_1507.150621-2200
Fix for an issue preventing users from Twitch Streaming Backward Compatibility titles.
Fix to address issues with Matchmaking in Backward Compatibility multi-player titles.
If you’ve been having trouble with Streaming your Xbox 360 titles this update should fix it. The new Xbox dashboard is expected to be sent out to Preview members by September, and full release by the holiday.
