Still based on the Debian Stable repositories, namely on Debian GNU/Linux 8.6 “Jessie,” Tails 2.9.1 is the first maintenance update to the 2.9 stable series, bringing updates for most of the pre-installed components, such as Tor 0.2.8.10 anonymous network client/server implementation and Tor Browser 6.0.8 anonymous web browser. Talking about Tor Browser, it looks like this first point release of Tails 2.9 switches the default search engine to DuckDuckGo, replacing the Disconnect.me one, which was already configured to redirect users to DuckDuckGo in previous releases of the Live CD. DuckDuckGo is perfect for protecting your anonymity while searching stuff online.
