There are new builds for both PC and mobile. 16176 has been released for the desktop and 15204 for mobile. Like the last update, not a lot of feature updates, but more on the back end. There is also a smaller list of devices that are supported on the mobile side, so some people may be disappointed in the dwindling Windows Phone support.

Today we are excited to be releasing Windows 10 Insider Preview Build 16176 for PC to Windows Insiders in the Fast ring. We’re continuing work to refine OneCore with some code refactoring so that teams can start checking in new code. So, you still won’t see any noticeable changes or new features in new builds just yet.
