Earlier this week, Microsoft released Windows 10 for PCs build 14393.187 as part of Patch Tuesday. An update for Windows 10 Mobile was notably missing at the time, but the same build would show up in the Release Preview and Slow rings yesterday for phones.
Less than 24 hours later, build 14393.189 has appeared for non-Insiders with unlocked devices. It"s completely unclear why the build number has increased, and it"s entirely likely that we"ll never find out. It"s a Production ring build, so we won"t see a changelog in the Feedback Hub, and Microsoft has never made an addition to the Windows 10 Update History for a Mobile exclusive.
While it"s not the same build, it"s clearly very similar to 14393.187, so here"s the full changelog for that build. You"ll see that much of it applies to Windows 10 Mobile, which is great news if you"re a Windows phone user.
Improved reliability of Windows Shell, map apps, Internet Explorer 11, and Microsoft Edge.
Addressed issue causing push-button reset to not work correctly and roll back on devices with language set to any of the Unicode languages.
Addressed issue causing devices to crash after disconnecting an e-reader that was attached to the device.
Addressed issue causing devices to not recognize a Secure Digital (SD) card if it is inserted and removed multiple times.
Addressed issue causing some apps to not respond to the commands in the app bar in Windows 10 Mobile.
Addressed issue that sometimes blocks alarm notifications in Windows 10 Mobile.
Improved support for using the camera app in Windows 10 Mobile Enterprise.
Addressed additional issues with rendering 4K resolution, missing Start menu tiles when running on battery, Internet Explorer 11, Microsoft Edge, Bluetooth compatibility, graphics, display rotation, app compatibility, Wi-Fi, Feedback Hub, Miracast, Windows Shell, revised daylight saving time, and USB.
Security updates to Microsoft Edge, Internet Explorer 11, Microsoft Graphics Component, Windows kernel, and Adobe Flash Player.
Note that this update is only available to unlocked devices in the Production ring. If you"re in the Release Preview or Slow rings and picked up 14393.187 yesterday, you won"t see anything new. Carrier-locked devices don"t seem to be getting it yet either, so you can most likely expect to see it in a week"s time.
This is the first cumulative update that Windows 10 Mobile has received since Microsoft shipped the Anniversary Update, which was almost a month ago. The previous build was 14393.67.
Update: Carrier-locked devices are now receiving the update.
