After a configuration update about 10 days ago it looks like Windows 10 Mobile is getting a faster release pace as it receives its second Cumulative Update in as many weeks.
From Supersite for Windows:
Windows 10 Mobile Build 10586.107 Released to Fast Ring Windows Insiders
Those Windows 10 Mobile Insiders who have been watching the PC testers get a new build every week for the last month have been pretty fired up about their lack of new builds for their preferred testing platform.
It now seems a trend is beginning to form for a similar release pattern for those Insiders as Microsoft has just made a new Cumulative Update available for Fast Ring Windows Insiders on Windows 10 Mobile.
With the release of Windows 10 Mobile Build 10586.107 today, those testers have now received two new builds in as many weeks.
