This is a important release for Ubuntu, 20.04 is a long-term support (LTS), meaning that this distro is supported until 2025. Ubuntu 20.04 has a clean and minimal desktop environment.
There are shown only icons for Home shortcut and Trash folders by default. The Top Bar and Ubuntu Dock neatly frame the new Focal Fossa mascot wallpaper.
New dark theme option that I love, is available in the Settings > Appearance panel. For more features check out and download the new Ubuntu 20.04 LTS.
