Ubuntu 12.04.4 is the latest of the distribution's live and installation images that include all recent security and bug-fix updates. This is Ubuntu's LTS (long-term support) release, providing security updates until 2017. As with 12.04.3, 12.04.4 contains an updated kernel and X stack for new installations on x86 architectures. As usual, this point release includes many updates, and updated installation media has been provided so that fewer updates will need to be downloaded after installation.

About Ubuntu

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.
