Here is the changelog for the Xbox Insider update on the Beta ring that brings Beam broadcasting

Earlier today, Brad Rossetti of the Xbox Insider team announced that Beam broadcasting would be arriving to Xbox Insiders on the Beta ring. The Xbox Insider team have now put up the changelog for the update that arrives to those on the Beta ring today.

Improvements

Beam

Beam is an innovative and interactive livestreaming service that gives viewers the ability to watch and deeply interact with their favorite game streamers in real-time, and you can now access Beam from the Guide on Xbox One! Please view this forum post for more information about Beam on Xbox One.

NOTE: To view the Broadcast icon for Beam in the Guide, you should download and install the new update. If you hard reboot your console after 2:00PM PST 2/25 without installing the new update, you’ll be able to see and use Beam in the Guide, but may experience sub-optimal streaming. This should be corrected by installing the update.

Beam App

The Beam app is now installed by default on Xbox One! To get started with the Beam app, navigate to My games & apps and search for Beam. Please use the Beam app and let us know if you encounter any issues via Report a problem.

Network Icon in Guide

Your connection status from Settings > Network is now represented in the Guide. To view the status of your network, press the Xbox button to launch the Guide and note the network icon in the upper right corner. The network icon will display your wireless connection strength or your wired connection. If you’re offline, the network icon will indicate you are not connected to a network.

Fixes

Networking

Fixed an issue which caused certain games to fail to connect to multiplayer (Destiny, Rocket League, Trove, Lies of Astaroth, …).

Upload Studio

Fixed an issue which caused Upload Studio to crash to Home on launch.

Audio

Fixed an issue which caused no audio output from the console.

Movies & TV

Resolved an issue with the media remote which caused the play and pause buttons to be unresponsive.

Known issues

Launching Games & Apps

When launching a game or app installed on the console which you do not own, a system message is displayed which has a “See in store” button. Selecting the “See in store” button will cause the console to crash.
Workaround: 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).

Audio

When switching between apps, there may rarely be an audible “pop”.

Notifications

Some users may not receive certain types of notifications.

Game Clips

After capturing a game clip, the game clip fails to automatically post to the Activity Feed (if your profile is configured to do so).
Workaround: Manually view game clips in Profile > Captures > Manage captures and post to the Activity Feed.

Sign-In

The console may fail to automatically sign in a profile with automatic sign-in enabled.

My Games & Apps

An app named “Developer Education” may appear in My Games & Apps. When launching this app no content will be displayed. This app is intended for development use and is not accessible on standard Xbox One consoles. The app will be removed from My Games & Apps in a future system update.

Cortana

• Cortana may take a long time to respond when activated while playing certain games.
• Scheduled Cortana reminders will not provide a notification if the user who created the reminder is signed in, but not the current active user.
• Using voice dictation sometimes causes the virtual keyboard to become unresponsive.

EA Access

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.

Screen Dimming

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).

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.

Wireless Display

The Wireless Display app fails to launch and immediately crashes to Home.

The update is available for Beta ring Insiders at 2PM PST.
