Microsoft has begun pushing the Windows 10 Mobile 10586.63 update that we reported on earlier. It’s releasing to just Windows Insiders so far, and as expected is looking like a cumulative update without any major feature updates.
We don’t have a changelog yet, but we’ll be sure to check back once we have more information. You can get to the update by opening Settings -> Update & Security -> Phone Update. Download the Windows Insider app if you haven’t already, and get that update going.
Update: Microsoft’s Gabe Aul promised a few minutes ago tia Twitter to provide an update on the build happenings. We’ll update you as we hear more.
