Ubuntu released a new version of popular OS with Long Term Support. There is a new head-up display (HUD) with even more minimalistic design, video search enhancement and updated software center.
Ubuntu Software Center now allows you to sync all installed apps with multiple computers, which can be very useful after fresh install.
Video Lens is a new video search feature. In addition to local search it also query online services like YouTube. I don’t see my self using this feature as I hardly got used to Unity.
