CEO Emmett Shear led the Day One keynote, revealing the new features to the attendees.
Some were niche — such as the better moderation tools, and the ability to designate some viewers as VIPs — but others were big and exciting.
One of the biggest updates was Squad Stream, which allows users to stream together from a single page.
Streamers in the squad will all have their streams visible in small panels, with one “main” streamer taking up the regular video space.
Another interesting change is Twitch Sings, a new karaoke mode done in collaboration with Harmonix, the company behind Dance Central and Rock Band.
Of the remaining features, the most interesting is a Snapchat extension, based on the desktop Snap Camera, which adds custom Lenses and streams of bits raining down from the sky whenever someone tips the streamer.
