While Amazon-linked Prime features are the big news out of TwitchCon, the livestreaming service is bringing some long-promised new features to users. Starting today, users can upload videos directly to Twitch. That means streamers can apply their video editing and production skills to archived clips for their audiences, without having to take them somewhere else, like YouTube Gaming. The feature was announced at TwitchCon last year, but at least it's here now in beta form.
