We are especially proud to present you Tails 2.0, the first version of Tails based on:

• GNOME Shell, with lots of changes in the desktop environment.
• Debian 8 (Jessie), which upgrades most included software and improves many things under the hood.
  
  This release fixes many security issues and users should upgrade as soon as possible.
