Microsoft has pushed Windows 10 Mobile Build 14393.479 (10.0.14393.479) to Insiders in Release Preview Ring. We last reported about sightings of this build on BuildFeed.
For the next Windows 10 Mobile CU build release, non-insiders may have to however wait till December 6. It will be interesting to see which one of these three builds makes the cut or will it be an even newer build.
The changelog for this build is not known yet but we will update this article when we come to know about the changelog.
Thanks Matheus for the tip. Cheers
