It's been a while since Windows 10 Mobile Insiders have seen a new preview build, but the wait is now over. Unfortunately, if you were hoping for some noteworthy additions, this build will not satisfy those expectations.
Microsoft says that Windows 10 Mobile build 15254.1 is now rolling out to Insiders on both the Slow and Fast rings. According to the announcement, this build contains all of the fixes from build 15252, along with the fixes included in the recent cumulative update KB4041676.
More importantly, Microsoft has labeled this build the release candidate for the Windows 10 Fall Creators Update for Mobile. The launch of the Fall Creators Update for PC is set for October 17, so it's likely this is the build that Windows 10 Mobile users will see roll out around the same time. Of course, things could change between now and then. Barring any major issues, however, we should expect to see build 15254.1 hit Release Preview users relatively soon.
