Now here's a blast from the (somewhat recent) past: the Trinity Desktop Environment. TDE is a fork of the last available release of the KDE 3.x series, coming into existence in 2008. The project's been under steady development ever since, and the most recent release is R14.0.3. since this is just a maintenance release, it might be more fitting to look at the release notes for R14.0.0, the base release, from december 2014.
Unlike previous releases TDE R14.0.0 has been in development for over two years. This extended development period has allowed us to create a better, more stable and more feature-rich product than previous TDE releases. R14 is brimming with new features, such as a new hardware manager based on udev (HAL is no longer required), full network-manager 0.9 support, a brand new compositor (compton), built-in threading support, and much more!
Honestly, I have no idea how many people still see value in a maintained KDE 3.x desktop, but since I've personally always been a fan of KDE 3 (KDE 4 never really managed to convince me), I'm glad his project is still around offering the option for those among us who want to use KDE 3.
