An anonymous reader writes "The six month cycle that Canonical adheres to for Ubuntu releases has come around again today. Ubuntu 12.10 'Quantal Quetzal' has been released. There's a whole range of new features and updates, but here are the most important: WebApps — treats online services as if they are desktop apps (Gmail, Twitter, Facebook); Online Services — control logins to all your services from a single window and get them integrated into search results (e.g. GDocs for file searches); Dash Preview — right click any icon, get a detailed preview of what it is; Linux kernel 3.5.4; GNOME 3.6; Nautilus 3.4; latest Unity; No more Unity 2D, fallback is the Gallium llvmpipe software rasterizer; Default apps updated (Firefox 16.01, Thunderbird 16.01, LibreOffice 3.6.2, Totem, Shotwell, Rythmbox); Full disc encryption available during install; Single, 800MB distribution for all architectures." It's now available for download. The next version, due in six months' time, will be called Raring Ringtail.
