New submitter Anand Radhakrishnan writes "The release candidate for the much-anticipated Linux Mint 15 'Olivia' is available for user testing. Its many new features include Cinnamon Control center, an improved login manager with HTML 5 support, a driver manager, and a lot of under-the-hood improvements. 'A new tool called MintSources, aka "Software Sources," was developed from scratch with derivative distributions in mind (primarily Linux Mint, but also LMDE, Netrunner and Snow Linux). It replaces software-properties-gtk and is perfectly adapted to managing software sources in Linux Mint. From the main screen you can easily enable or disable optional components and gain access to backports, unstable packages and source code.' This release with Cinnamon looks really tempting."
