KDE neon is a Ubuntu-based Linux distribution and live DVD featuring the latest KDE Plasma desktop and other KDE community software. Besides the installable DVD image, the project provides a rapidly-evolving software repository with all the latest KDE software. Two editions of the product are available - a "User" edition, designed for those interested in checking out the latest KDE software as it gets released, and a "Developer's" edition, created as a platform for testing cutting-edge KDE applications.

Plasma LTS Edition Live/Install Image includes Plasma LTS release but otherwise same rolling updates, good for testing, not recommended for a stable system.
