Ubuntu 14.10 was released.
"Ubuntu 14.10, the latest desktop release is today available for download from Canonical. This release focuses on the developer experience, overall quality, and brings a number of important features and security enhancements. The Ubuntu desktop continues to be intuitive, easy to use and reliable for users all over the world. Ubuntu is a popular choice for developers targeting the cloud, mobile or devices because it is easy to use, fast and secure. Ubuntu 14.10 introduces the first iteration of the Ubuntu Developer Tools Centre, which makes it even easier to develop on Ubuntu. It downloads all the Android toolkits and their dependencies and integrates them with the launcher in a single command. This is first available for Android and will soon extend to other platforms such as Go and Dart."
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.
