Tails 2.0 發布，基于 Debian 的 Linux 發行
Tails 2.0 發布，更新如下：
New features
Tails now uses the GNOME Shell desktop environment, in its Classic mode. GNOME Shell provides a modern, simple, and actively developed desktop environment. The Classic mode keeps the traditional Applications, Places menu, and windows list. Accessibility and non-Latin input sources are also better integrated.
To find your way around, read our introduction to GNOME and the Tails desktop.
Upgrades and changes
Debian 8 upgrades most included software, for example:
Many core GNOME utilities from 3.4 to 3.14: Files, Disks, Videos, etc.
LibreOffice from 3.5 to 4.3
PiTiVi from 0.15 to 0.93
Git from 1.7.10 to 2.1.4
Poedit from 1.5.4 to 1.6.10
Liferea from 1.8.6 to 1.10
Update Tor Browser to 5.5 (based on Firefox 38.6.0 ESR):
Add Japanese support.
Remove the Windows camouflage which is currently broken in GNOME Shell. We started working on adding it back but your help is needed!
Change to
systemdas init system and use it to:Sandbox many services using Linux namespaces and make them harder to exploit.
Make the launching of Tor and the memory wipe on shutdown more robust.
Sanitize our code base by replacing many custom scripts.
Update most firmware packages which might improve hardware compatibility.
Notify the user if Tails is running from a non-free virtualization software.
Remove Claws Mail, replaced by Icedove, a rebranded version of Mozilla Thunderbird.
Fixed problems
HiDPI displays are better supported. (#8659)

The Amnesic Incognito Live System (Tails) 是基于 Debian 的自啟動光盤或 USB 發行，其目標是為用戶提供完整的因特網匿名功能。該發行裝備了一些因特網應用程序，包括網頁瀏覽器、IRC 客戶端、郵件 mail 客戶端、即時消息信使，這都以安全為理念進行了預配置，并對網絡流量進行了匿名性處理。為達到此目標，Incognito 使用了 Tor 網絡，以使得網絡流量很難被追蹤。
