Microsoft has released a new preview build of Windows 10 Mobile for users in the Fast Ring of its Insider program. The new build number is 14267 and is the same one for the Windows 10 PC preview version that was released on Thursday.

Microsoft's Gabriel Aul stated:

"While we have been releasing preview builds for PC from our development branch for a while now, this is our first new preview build for Windows 10 Mobile from our Development Branch this year. As I mentioned a couple of weeks ago, initially we'll make new builds from our Development Branch available only to devices that shipped with Windows 10 Mobile. Currently this includes the Lumia 950, 950 XL, 550, and Xiaomi Mi4. We plan to expand from there as we release Windows 10 Mobile to other devices."
