Windows 10 Mobile build 14393.221 arrives for Release Preview

Despite it not technically being a 'Patch Tuesday' Microsoft is pushing out some new OS updates for those on Release Preview. Windows 10 Mobile build 14393.221 is now live for those on the Windows Insider Release Preview Ring.

As to what exactly is new, we have to wait and see until a proper changelog is posted. For now, we'll just have to assume some bug fixes and optimizations. Assuming all goes well with the update non-Insiders should expect it sometime in October during the regular 'Patch Tuesday' period.

Thanks, Luiz, and William, for the tip!
