When the upstream proposes an update to the Kernel, Desktop, or Video Drivers, the Focus Team runs extensive tests to make sure the changes work on your system. If we find an issue, we work with KDE, Kubuntu, Ubuntu, and other teams to help fix it before a release. Actions taken include submitting and tracking bugs, providing acceptance reports, creating feature proposals, developing code changes, and assembling kernel patches.

The Focus team performs this testing in good faith to assist developers and users create better software; however, this service cannot change the "Terms of Use" of any software component, and is therefore provided with no warranty. These "Terms of Use" for each component is defined by its individual license, as described in the Terms and Conditions page.
