Tails 2.5 发布了，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。 主要更新： Tor Browser 更新到 6.0.3 ，基于 Firefox 45.3. Icedove 更新到 45.1. (#11530) 问题修复： The automatic account configuration of Icedove used to freeze when connecting to some email providers.

(#10933) A spurious error message used to sometimes appear when creating an account in Icedove and providing its password. (#11550) Fix some time synchronization problems, by replacing obsolete and unreliable servers, and decreasing a timeout.
