Squad Streams is the first major new addition. It allows up to four players to broadcast together on one stream. More specifically, that means if four people are playing Call of Duty Black Ops 4, it's possible for all four streams to be visible on the same screen. And with a click, users can choose to enlarge a specific window to get a better view. This can help audiences see all the action, especially when one player is the center of attention.

Go live on Twitch with up to three other streamers, all in a single view.

The next major addition should be a well of viral goodness. In partnership with music developer Harmonix -- the team behind Rock Band -- Twitch will be launching a new karaoke game called Sings that will be rely heavily on community engagement. Be certain that users will request streamers sing Rick Astley's "Never Gonna Give You Up" and A-ha's "Take on Me."

You already stream your heart out. Soon, you can sing your heart out, too.

New moderation tools were also announced. Moderators can click on a username in chat to see how long that person has been on Twitch, the number of timeouts and bans given, and leave comments for the stream owner and other moderators to see. These features are expected to drop in January.

Along with Squad Streams and Sings, other features announced were Twitch Rivals, a new competitive tournament series with $5 million in prizes, Snap's AR selfies, and better ways to share clips, and new VIP memberships for a streamers' superfans. There were no new announcements for Amazon Prime users, meaning that for the time being, ads will remain.
