You can help Tails! The first release candidate for the upcoming version 1.0 is out. Please test it and see if it works for you.

How to test Tails 1.0~rc1?

  1. Keep in mind that this is a test image. We have made sure that it is not broken in an obvious way, but it might still contain undiscovered issues.

  2. Either try the automatic upgrade, or download the ISO image and its signature:

    Tails 1.0~rc1 ISO image

    Tails 1.0~rc1 signature

  3. Verify the ISO image.

  4. Have a look at the list of longstanding known issues.

  5. Test wildly!

If you find anything that is not working as it should, please report to us! Bonus points if you check if it is a longstanding known issue.

How to automatically upgrade from 0.23?

These steps allow you to automatically upgrade a device installed with Tails Installer from Tails 0.23 to Tails 1.0~rc1.

  1. Start Tails 0.23 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 choose System ▸ About Tails to confirm that the running system is Tails 1.0~rc1.

What's new since 0.23?

  • Bugfixes

    • Disable inbound I2P connections. Tails already restricts incoming connections, but this change tells I2P about it.
    • Fix link to the system requirements documentation page in the Tails Upgrader error shown when too little RAM is available.
  • Minor improvements

    • Upgrade I2P to 0.9.12-2~deb6u+1.
    • Import TorBrowser profile. This was forgotten in Tails 0.23 and even though we didn't explicitly set those preferences in that release they defaulted to the same values. This future-proofs us in case the defaults would ever change.
    • Import new custom version of Tor Launcher:
