Tails 2.5 was released on August 2. It includes a number of fixes for bugs and security holes.


  • We updated our roadmap, listing our priorities for the next years.

  • Use a dedicated homepage for Tor Browser in Tails to be able to customize what we are showing when people start Tails (#11725).

  • We enabled address space layout randomization in the Linux kernel (kASLR) to improve protection from buffer overflow attacks.

  • We installed rngd to improve the entropy of the random numbers generated on computers that have a hardware random number generator.

  • Upgrade to Linux 4.6. This should improve the support for newer hardware (graphics, Wi-Fi, etc.)

  • Improved the automatic configuration of Icedove for some use cases (#11536), and started writing automated tests for Icedove.

  • We've successfully provided an AppArmor profile to Debian's Icedove package and started integrating it into Tails (#10750).

  • We started porting Tails to Debian 9 (Stretch).

Documentation and website

  • We documented how to install Tails Installer in Ubuntu 16.04 (#11570). Unfortunately, this has to be done on the command line since Tails Installer is not listed in the new Ubuntu Software yet. But we are working on fixing this (#11569).


  • 658 ISO images were automatically built and tested by our continuous integration infrastructure.
  • We started porting Tails to Debian 9 (Stretch). Adjusting our test suite to make it able to provide feedback about our early Tails 3.0 ISO images is a critical part of this project. To do so, in the past we had to go through a tedious process of updating the dozens of pictures that we ask Sikuli to recognize; but this time, thanks to the work we recently did to support Dogtail in our test suite, we are able to remove many such pictures, and replace them with higher-level means of interacting with graphical user interfaces. So far we could remove 31 such images. This change brings two major benefits: it makes our test suite more robust, and it makes our project more sustainable, by decreasing the cost of porting Tails to future versions of Debian.
  • Until recently, the parts of our test suite that rely on emulated USB storage devices were fragile on our Jenkins setup. This prevented us from running a number of tests there, e.g. those involving persistence. We kept working on it, as reported last month, both in Tails Installer itself and in our test suite (#11588, #11582). As a result, we were able to re-enable these tests on production branches in August.
