Ubuntu 12.04.5 is a new set of live and installation images that include all recent security and bug-fix updates for the project's older LTS (long-term support) release, supported until April 2017. 12.04.5 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.
