How to automatically upgrade from 1.3.2?

These steps allow you to automatically upgrade a device installed with Tails Installer from Tails 1.3.2 to Tails 1.4~rc1.

  1. Start Tails 1.3.2 from a USB stick or SD card (installed by the Tails Installer), and set an administration password.

  2. Run this command in a Root Terminal to select the "alpha" upgrade channel and start the upgrade:

    echo TAILS_CHANNEL=\"alpha\" >> /etc/os-release && \
  3. Once the upgrade has been installed, restart Tails and look at Applications ▸ Tails ▸ About Tails to confirm that the running system is Tails 1.4~rc1.

What's new since 1.3.2?

Changes since Tails 1.3.2 are:

  • Major new features

    • Upgrade Tor Browser to 4.5, which introduces many major new features for usability, security and privacy. Unfortunately its per-tab circuit view did not make it into Tails yet since it requires exposing more Tor state to the user running the Tor Browser than we are currently comfortable with. (Closes: #9031)
    • Upgrade Tor to Like in the Tor bundled with the Tor Browser, we patch it so that circuits used for SOCKSAuth streams have their lifetime increased indefinitely while in active use. This currently only affects the Tor Browser in Tails, and should improve the experience on certain websites that otherwise would switch language or log you out every ten minutes or so when Tor switches circuit. (Closes: #7934)
