We are releasing a new build to the Alpha audience today at 6.00pm PDT with performance fixes.

• If your console is in Instant-On mode and you have been selected to receive the update, it will download and install the update and reboot to standby.
NOTE: Once the update is available to you, you can manually begin the update by launching the Guide and navigating to All Settings > System > Updates.
• If your console hasn’t downloaded and installed the update by 1:00 AM PDT 9/15/2017 (8:00AM GMT 15/9), you will be prompted to do so at that time.

OS version released: rs3_release_xbox_dev_1710.170910-1900
Available: 6:00PM PDT 9/13 (1:00AM GMT 14/9)


• Game DVR
Alpha Xbox Insiders, awesome new GameDVR features added today! Capture at 1080p, and capture directly to an external drive.


• Games & Apps
Miscellaneous performance fixes when switching between games or apps.


• Blu-Ray Player
3D Blu-Ray content now correctly plays in 3D.

• Virtual Keyboard
When using virtual keyboard the auto suggest feature does not function.

• Light Theme
There are some known visual contrast issues in messaging, the entertainment twist, and the Mixer twist—you may see white on white. Fixes will be coming soon.

• Sign-in
When using Arabic or Hebrew language and signing in with a profile using the “Lock it down” security preference, the sign-in screen which requests Microsoft account e-mail address and password is distorted. This does not affect the profile if it is set to use the “Ask for my passkey” or “No barriers” security preferences.

Workaround: Set the console to use another language, sign-in, and set the profile’s security preference to “Ask for my passkey” or “No barriers”. Alternatively, you can still type in your password as normal using the virtual keyboard though the screen is distorted.

• Netflix
When using Hebrew language, Netflix fails to launch.

• Home
Images on the Mixer tab may appear clipped or duplicated.
