After starting Tails and connecting to Tor, <span class="application">Tails
Upgrader</span> automatically checks if upgrades are available and then
proposes you to upgrade your USB stick. The upgrades are checked for and downloaded
through Tor.

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.

Requirements:

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

connection by then), you can start <span class="application">Tails
Upgrader</span> later by opening a terminal and executing the following
command:</p>
