Ubuntu 13.10 was released.
"Canonical today announces the availability of Ubuntu 13.10 for desktop and smartphone. Ubuntu's first true mobile release delivers the streamlined core OS and mobile user interface that pave the way for full device convergence and create a unique platform for modern computing. Canonical is working with partners to bring Ubuntu smartphone devices to market in 2014. The desktop version of Ubuntu 13.10 reflects much of that progress, with scopes that organise home, apps, music, video content, lower device memory and graphics requirements and substantial improvements in battery and memory efficiency."
Ubuntu is a complete desktop Linux operating system, freely available with both community and professional support. The Ubuntu community is built on the ideas enshrined in the Ubuntu Manifesto: that software should be available free of charge, that software tools should be usable by people in their local language and despite any disabilities, and that people should have the freedom to customise and alter their software in whatever way they see fit. "Ubuntu" is an ancient African word, meaning "humanity to others". The Ubuntu distribution brings the spirit of Ubuntu to the software world.
