To check which version of Tails you are currently running, choose **Apps ▸ Tails ▸ About Tails**.

After starting Tails and connecting to Tor, *Tails Upgrader* automatically checks if upgrades are available and then proposes you to upgrade your USB stick. The upgrades are checked for and downloaded through Tor.

The upgrade is much smaller to download than a full USB image.

If you decide to do the upgrade, click on **Upgrade now**, and follow the assistant through the upgrade process.

No automatic upgrade is available from our website for this version.

The automatic upgrade failed and you need to repair a Tails USB stick.

After connecting to Tor, a dialog informs you if you have to upgrade your USB stick using *Tails Cloner* to a newer version of Tails.

<p>We estimated that, to actually reduce the
overall download size, it's only worth it to do 1 manual upgrade every year if
you apply all upgrades of Tails.</p>
