Linux Mint 17.1 is a long-term support release which will be supported until 2019. The previous version of Linux Mint used KDE 4.13. In this release, KDE is upgraded to version 4.14. Support was added in MDM and in the session for the KDE wallet to be fully integrated with Linux Mint. Although a Wallet Manager is present for configuration purpose, no interaction is needed for the KDE wallet to work. The wallet is created automatically with your first login, and it opens automatically in the background with every new session. The Update Manager now groups packages together according to their source package.
