Yesterday Microsoft released Windows 10 Build 10565 to Windows Insiders in Fast Ring.
Now Gabriel Aul, head of the Windows Insider program, tweeted that they are currently evaluating mobile build 10549.4. We hope this build can hit Insiders if all goes good.
@OyeRohit 10549.4 is the build we’re evaluating right now.
However, we expect a new Windows 10 Mobile build coming later today or early tomorrow to Windows Insiders in Fast Ring.
