The login screen can now be themed in HTML 5 and two new tools, 'Software Sources' and 'Driver Manager', make their first appearance in Linux Mint. MDM now features 3 greeters (i.e. login screen applications): a GTK+ greeter, a themeable GDM greeter for which hundreds of themes are available, and a brand-new HTML greeter, also themeable which supports a new generation of animated and interactive themes."

As with previous releases, the newest Mint iteration, "Olivia," comes in two distinct flavors: Cinnamon and MATE. While both have received a bit of polish, it's the fresher Cinnamon that has gotten the most attention. Version 1.8 of the desktop environment has received plenty of bug fixes, along with a new dedicated settings panel that bypasses the GNOME control center. Support for "Desklets" (read: widgets) has also been added and the log-in screen is completely customizable through HTML5. Both versions benefit from the addition of MintSources, for managing software repositories, and MintDrivers, for managing drivers, obviously. While they'll come in handy for consumers, the biggest advantage is that IT managers may now be more accepting of the refreshingly green Ubuntu derivative. The developers are calling version 15 their most ambitious release yet, and while we're not completely convinced that's true, it's certainly a significant upgrade over November's Nadia.
