Mahdi Fattahi has announced the availability of the beta release of AriOS 4.0, an Ubuntu-based distribution featuring a heavily modified GNOME 3 desktop and many additional software applications: "I'm very happy to announce AriOS 4.0 beta, based on the upcoming long-term support (LTS) version of Ubuntu. Although both Ubuntu 12.04 and AriOS are in beta, I consider this release a very stable and robust system, as Canonical has done a great job on making 'Precise' stable and bug-free. AriOS comes with the latest updates from the 'Precise' development branch up to March 26, 2012. In this release we offer a great array of the latest and greatest free desktop environments. Like before, AriOS comes with its own proven desktop layout, based on GNOME 3 and the awesome Avant Window Navigator. Also available are the latest versions of Unity, GNOME Shell, Unity 2D and GNOME classic.
