If you are one of the select few to have been chosen for the Preview Alpha ring of the Xbox Insider Program, a new build is available for you today. The build number is 15023.1002, which is up from 15009.1017.
The OS version listed in the release notes is rs_xbox_dev_flight.170128-2057, which is a bit peculiar. The original Creators Update Insider Preview and the build that followed both had the 'rs2' prefix, and in case you're not familiar, 'rs2' is Redstone 2, also known as the Creators Update, while 'rs' would be Redstone, or the Anniversary Update. Don't worry; this is most certainly still a Creators Update build, but the build string is just a little peculiar.
Today's update doesn't include any new features, such as the built-in Beam streaming that was promised, but there are some fixes:
Resolved an issue which caused some See-It-Say-It content to fail to display on Home, Community, OneGuide, and Store.
You should now be able to purchase in-game content for Battlefield 1 and Happy Wars.
When attempting to launch a pre-ordered title from the Game Hub, the title now displays the correct "too early" error message.
In-game and headset audio should work normally when switching between apps or resuming app from connected standby.
Trove now launches correctly when the console is set to a locale other than en-US\USA.
Dishonored: Definitive Edition
Fixed an issue which caused Dishonored: Definitive Edition to crash after launch with the console set to pt-BR\Brazil
Halo Wars: Definitive Edition
Fixed an issue which caused in-game text to fail to display in Halo Wars: Definitive Edition.
Of course, there are still some known issues:
When launching the Ubisoft Club app, the screen automatically starts scrolling down, and prevents the user from scrolling back up.
With profile sign-in settings set to “Lock it down”, you may be unable to sign-in again after playing a game, then signing out.
Workaround: Hard reset the console (hold down the button on the front of the console for five seconds until it fully powers down, then power it back on).
The EA Access app may indicate you are not an EA Access subscriber when you are. This does not affect your ability to download or play games from the Vault, or receive discounts on EA titles.
Microsoft Edge webpages which have been pinned on the Jump tab fail to launch the webpage.
The screen may dim after a short amount of time while viewing videos in certain apps (Hulu Plus).
Settings - Ease of Access
When enabling the Mono output setting in Ease of Access - Audio, Settings becomes unresponsive, crashes, and fails to launch on subsequent attempts.
Workaround: To launch Settings, perform a hard reset (hold down the button on the front of the console for five seconds until it fully powers down, then power it back on).
Settings - Display & sound
The Audio output page is under construction and some of the new settings are not yet functional. New support is planned for Dolby Atmos for home theater, Dolby Atmos for headphones, and more in upcoming builds. An announcement will be made when these new features are ready to try out; enabling these settings now will have no effect.
The IGN app launches and immediately crashes to Home.
The Wireless Display app fails to launch and immediately crashes to Home.
Microsoft also says that there are some new Quests available in the Insider Hub, which you should really go check out at some point. Remember, if you become inactive as an Insider, you can lose your place in the Preview Alpha ring.
