I had downloaded Ubuntu 16.04 Daily ISO and was periodically updating it using zsync. I updated it this morning to version 20-Apr-2016 22:30 and assuming it that it is going to be the Final version installed it to hard disk replacing Ubuntu 14.04.4 Trusty (which I was not using anyway).
See the screen shot below with Unity Launcher moved to Bottom using Unity Tweak Tool (which is now available in Software).
