Ubuntu 12.10 "Quantal Quetzal" officially released
Nearly six months after Ubuntu 12.04 LTS arrived, Canonical and the Ubuntu developers have released version 12.10 of their Ubuntu Linux distribution, code-named "Quantal Quetzal". The new version of the popular open source operating system uses a kernel based on the 3.5 Linux kernel and updates Unity desktop with a number of new features and enhancements.
One of the more controversial changes to the Unity desktop shell is the addition of a new Shopping Lens, which shows commercial results from Amazon's online store when searching. The 12.10 release further integrates Canonical's Ubuntu One services, including improvements to the Ubuntu One Music Store, introduces support for Web Apps and is the first Ubuntu version to support UEFI Secure Boot.
