Trinity Desktop Environment
The Trinity Desktop Environment (TDE) project is a feature rich desktop environment for Unix-like operating systems with a primary goal of retaining a traditional, efficient and productive user interface.
TDE was born as a fork of the K Desktop Environment version 3.5, which was originally written by the KDE Team, a world-wide network of software engineers committed to Free Software development. The name Trinity was chosen because the word means Three as in continuation of KDE 3. Since then, TDE has evolved to be an independent and standalone desktop environment project. Over time, continued development has polished off many rough edges that were present in the final release of KDE 3.5.10 and many new and useful features have been added to keep the environment up-to-date.
Current release
The current stable release of TDE is R14.1.7.
