The Ubuntu Developer Summit held in May 2012 set the priorities for this release. They are forecast to include an improved boot up sequence and log-in screen, dropping Unity 2D in favor of lower hardware requirements for Unity 3D, wrap around dialogs and toolbars for the HUD and a "vanilla" version of Gnome-Shell as an option. The release would likely include GNOME 3.6, Python 3 and the 3.5 Linux kernel.[157] It would ship with Python 3 in the image, but with Python 2 available in the repositories, via the "python" package.[158] The kernel will have the PAE switched on by default.[159]
