<emphasis role="strong">Unsupported updates:</emphasis> When new versions of popular software are released they are sometimes <quote>back-ported</quote> to an older version of Xubuntu so that users can benefit from new features and fixes for problems. These backports are unsupported, may cause problems when installed and should only be used by people who are in desperate need of a new version of a software package which they know has been backported.

Most of the software available for Xubuntu is free, open-source software. This software is free for anyone to install and use, and people can modify the software and redistribute it if they like. Xubuntu is built from this type of software.

<emphasis role="strong">Non-free software</emphasis> is software which is not freely redistributable or modifiable. This makes it difficult for the Xubuntu developers to improve the software and correct problems, so it is normally recommended that you use <ulink url="http://www.ubuntu.com/ubuntu/philosophy"> free software</ulink> instead.

<emphasis role="strong">Restricted software</emphasis> is software which has restrictions on its use, preventing it from being classed as free software. Non-free software is a type of restricted software, where the restrictions are due to the software having a non-free license. Other reasons for software being classed as restricted include legal issues (use of some types of software is illegal in some countries) and patent issues (some software requires a patent license to be used legally).
