<h1 id="automatic">Automatic upgrade using <i>Tails Upgrader</i></h1>

You only need a single Tails USB stick. The upgrade is done on the fly from a running Tails. After upgrading, you can restart and use the new version.

The upgrade mechanism includes cryptographic verification of the upgrade. You don't have to verify the USB image yourself anymore.

After connecting to Tor, if an upgrade is available, a dialog appears and proposes you to upgrade your USB stick.
