Tails 1.7 发布，主要更新如下： You can now start Tails in offline mode to disable all networking for additional security. Doing so can be useful when working on sensitive documents. We added Icedove, a rebranded version of the Mozilla Thunderbird email client. Icedove is currently a technology preview. It is safe to use in the context of Tails but it will be better integrated in future versions until we remove Claws Mail. Users of Claws Mail should refer to our instructions to migrate their data from Claws Mail to Icedove. 更多内容请看：发行说明 下载： download or upgrade The Amnesic Incognito Live System (Tails) 是基于 Debian 的自启动光盘或 USB 发行，其目标是为用户提供完整的因特网匿名功能。该发行装备了一些因特网应用程序，包括网页浏览器、IRC 客户端、邮件 mail 客户端、即时消息信使，这都以安全为理念进行了预配置，并对网络流量进行了匿名性处理。为达到此目标，Incognito 使用了 Tor 网络，以使得网络流量很难被追踪。 Tails 1.7 发布，基于 Debian 的 Linux 发行下载地址
