The update uses a new, more modern Gnome shell that gives it a more "modern, simple, and actively developed desktop environment," according to the developers. At the same time, Tails 2.0 keeps the applications, places menu, and windows list front and center. In addition to fixing the security bugs and updating to the latest version of the Tor browser (5.5), the team also made services harder to exploit by "sandboxing" them, improved the shutdown memory wipe, sanitized the code by replacing custom scripts and replaced the email system with Icedove, a Mozilla Thunderbird offshoot.

The new version is now available to download. In fact, if you're already using version 1.8.2 of Tails, the developers said it has "numerous security holes," and advised everyone to update to Tails 2.0.
