The latest version of Linux Mint running the KDE desktop is now available as a release candidate.
Linux Mint 15, code-named Olivia, improves various features of the operating system, which is based on Ubuntu 13.04.
Another addition is a tool for managing software repositories called Software Sources, which replaces software-properties-gtk, and is designed to have a more intuitive GUI than its predecessor.
The new driver manager MintDrivers provides a better looking front-end to make it simpler to manage drivers than it was using software-properties.
Other improvements include Update Manager being given the ability to refresh the APT cache without any user intervention and bug fixes to the Welcome Screen.
The desktop is based on KDE 4.10 desktop environment, which features improvements to the look and security of the desktop via upgrades to Plasma Workspaces, new features for the Kate text editor, KMail and the Konsole terminal, as well as various other enhancements and bug fixes.
