Among the topics discussed by the developers at Ubuntu Developer Summit 13.05 were the planned new features for Ubuntu 13.10. The next version of the distribution, code-named “Saucy Salamander”, could include early versions of Ubuntu’s Mir display server and have the Qt-based Unity Next desktop environment for testing. However, the default configuration will continue to include the graphics stack of Ubuntu 12.10 with X11, Compiz and Unity 7. By 2014, Canonical plans to unify the code base for Ubuntu’s smartphone, tablet and PC desktops, based on Mir and Unity Next.
