Here is the full list of new features, via Xbox Wire:
New Xbox Avatars
The new Xbox Avatars are expressive, creative and, most importantly, bring to life the community of fans they represent. The Avatar Editor features a wide range of body types, and the entire Avatar closet supports all of them, enabling you to uniquely tailor your Avatar however you see fit.
Avatars will appear across your Xbox One. You will see your own Avatar on your profile, as well as on the profile pages of anyone who has chosen to represent themselves as an Avatars. You’ll also find Avatars on activity feed posts, Friend blocks on the Home screen, Gamerscore leaderboards, club headers, profile comparisons, and more. In addition to all the items that are available at launch, there is also a new Avatar Store where you can obtain even more new Avatar items, including licensed designs from Halo, Gears of War, and more. With new content every month, the Avatar Store is a diverse marketplace of clothing, outfits, props, and accessories to make your Avatar even more unique.
Once you’ve created your new Avatar, you can use the Photobooth feature to capture a great photo of your Avatar to use as your Gamerpic. In addition to the mood that you set for your Avatar, you can also use the Photobooth to pose your Avatar using a multitude of different emotes, each of which can be paused and advanced frame-by-frame with more control than ever before. Rotate and zoom controls help you capture the exact pose that you’re looking for, and a wide variety of background colors enable you to set the scene.
If you prefer your Xbox Original Avatar, that’s okay too! The new Xbox Avatar Editor also enables you to compare and choose which version of the Xbox Avatar best represents how you want to be seen on Xbox Live. If you choose to represent yourself as an Xbox Original Avatar, all the content from your Xbox Original avatar’s closet continues to be available via the Xbox Original Avatars app on Xbox One and Windows 10.
Xbox Skill for Cortana and Alexa
The Xbox Skill for Cortana and Alexa is available today in the U.S. This feature enables people to use their voice to navigate and interact with Xbox through Cortana and Alexa-enabled devices – expanding voice navigation beyond previous Kinect and headset capabilities. With the Xbox Skill, people can use voice commands to power on/off their console, adjust volume, launch games and apps, start and stop broadcasts on Mixer, capture screenshots, and more. For example, if you have the Xbox skill enabled on your Echo just say “Alexa, launch Forza Horizon 4” and this command will automatically turn on your console, sign you in, and launch Forza Horizon 4. Look for the Xbox Skill in the Alexa Skill Store or the Cortana Skill Store to get started. To set up Alexa, just say, “Alexa, open Xbox” and to set up Cortana, just say, “Hey Cortana, open Xbox”, or search for “Xbox” in the assistant skill store. To learn more about this new feature, see our previous post.
Additionally, starting tomorrow in the United States, anyone who buys a qualified Xbox One S or Xbox One X bundle at Amazon.com will also get a new Amazon Echo Dot, but don’t wait too long because this offer is only available while supplies last.
Dolby Vision video streaming on Xbox One
Xbox is committed to bringing rich entertainment options to our fans. Today we are excited to launch our latest entertainment option, Dolby Vision HDR video streaming support across Xbox One S and Xbox One X! Dolby Vision enables select TVs to deliver enhanced HDR with dynamic scene-by-scene precision and accuracy versus standard HDR, which is static for the entire movie/show you are watching. If you have a TV that supports the latest version of Dolby Vision and a Premium Netflix subscription, jump in and experience incredible brightness, contrast, and color for yourself today! Dolby Vision on Netflix with a premium subscription will be supported at launch with more Dolby Vision apps adding support in the coming months.
To enable Dolby Vision on your console, navigate to Settings -> Display and sound -> Video output -> Video modes -> Allow Dolby Vision. If you need more assistance setting up the feature or want more information on supported TVs, check out this blog post.
New languages for Narrator
Xbox is committed to being more accessible and inclusive. Today we are adding five additional languages to Narrator on Xbox One, including Spanish, Portuguese, Polish, Swedish, and Dutch. We’re also adding an Australian version of English language for Narrator, so Australian users will no longer have to select United States or United Kingdom English to use Narrator.
