With very little fanfare Microsoft have released new build of Windows 10 Mobile for Windows Insiders. The build has been released to the both the fast and slow rings and doesn’t contain any new features. It adds a cumulative update (KB4041676) to the previous build of 15252 and is the release candidate for the Windows 10 Fall Creators Update for Mobile.
So unless there are any show stopper bugs this will be the build that rolls out to Windows 10 Mobile users starting next week.
UPDATE 10/11: We have released Windows 10 Insider Preview Build 15254.1 for Mobile to Windows Insiders in the Fast and Slow rings. This build is currently the release candidate for the Windows 10 Fall Creators Update for Mobile. This build includes all the same fixes from Build 15252 and also includes all the improvements from KB4041676.
Here is my hands on video of the last build:
