Ubuntu 6.06 (Dapper Drake), released on 1 June 2006, was Canonical's fourth release, and the first long-term support (LTS) release. Ubuntu 6.06 was released behind schedule, having been intended as 6.04. It is sometimes jokingly described as their first "Late To Ship" (LTS) release. Development was not complete in April 2006 and Mark Shuttleworth approved slipping the release date to June, making it 6.06 instead. Ubuntu 6.06's support ended on 14 July 2009 for desktops and ended in June 2011 for servers. Ubuntu 6.06 included several new features, including having the Live CD and Install CD merged onto one disc, a graphical installer on Live CD (Ubiquity), Usplash on shutdown as well as startup, a network manager for easy switching of multiple wired and wireless connections, Humanlooks theme implemented using Tango guidelines, based on Clearlooks and featuring orange colors instead of brown, and GDebi graphical installer for package files. Ubuntu 6.06 did not include a means to install from a USB device, but did for the first time allow installation directly onto removable USB devices.
