A whole world of small innovations
Ubuntu comes with everything you need to run your organisation, school, home or enterprise. All the essential applications, like an office suite, browsers, email and media apps come pre-installed and thousands more games and applications are available in the Ubuntu software centre.
Ubuntu has always been free to download, use and share. We believe in the power of open source software; Ubuntu could not exist without its worldwide community of voluntary developers. Long Term Support (like the 15.04 version) releases give you five years of security patches and updates, but also the other (standard releases) release have a nine months support period and, after that, you just need to operate the upgrade process.

A lot of under the hood improvements
Updates in Ubuntu 15.10 regard many core packages: first of all, the new 4.2-based kernel. Then a switch to GNU gcc-5 and much more development tools changes. Ubuntu 15.10, Desktop Version, has seen many small and big not visible improvements, with newer versions of GTK and Qt. There are also the updates to all the major packages of the distribution, like Firefox and LibreOffice. Stability improvements to the environment and some minor tweaks to Unity. Last but not least, the GNOME window bars, the new AMDGPU kernel driver for supporting Radeon GPUs and the F2FS file-system encryption support.
