[[!meta title="Tails 2.9 is out"]]
[[!tag announce]]

This release fixes [[many security
issues|security/Numerous_security_holes_in_2.7.1]] and users should
upgrade as soon as possible.

<div class="caution">

<p>
<strong>
Security flaw when installing additional software in 2.9 and earlier
</strong>
</p>

<p>
Right before releasing Tails 2.9, we learned about
<a href='https://security-tracker.debian.org/tracker/CVE-2016-1252'>
a critical security issue in APT</a>, the software packages
system used by Tails and Debian.
</p>

<p>
To remain safe while using Tails 2.9:
</p>

<ul>
<li>
Do not use the <i>Synaptic</i> package manager.
</li>
<li>
Do not use the <tt>apt-get</tt> or <tt>apt</tt> commands in the terminal.
</li>
<li>
Do not use the [[<i>Additional software packages</i> persistence
feature|doc/first_steps/persistence/configure#additional_software]].
</li>
</ul>
  
<p>
We will release Tails 2.9.1 to fix this issue before the end of the
week.
</p>
