The privacy-focused Linux distribution Tails has released version 7.4, introducing the ability to save language, keyboard layout, and format preferences persistently on USB sticks. This update also brings upgrades to Tor Browser and Thunderbird, along with several bug fixes. The release occurred on January 15, 2026, as the fourth minor update in the 7.x series.
Tails, a portable Linux distribution based on Debian GNU/Linux designed to protect users against surveillance and censorship by routing all internet traffic through the Tor network, unveiled version 7.4 on January 15, 2026. This update follows Tails 7.3.1 by about a month and is available for download as ISO and USB images for 64-bit systems from the official website.
The headline feature allows users to save their preferred language, keyboard layout, and formats directly from the Welcome Screen to the USB stick. These settings apply automatically upon restarting Tails. To facilitate passphrase entry during early boot before full decryption, the settings are stored unencrypted, but developers stress that only basic preferences are included, with no additional personal data.
Several core components received updates. The default web browser advances to Tor Browser 15.0.4, built on Mozilla Firefox 140 ESR, which adds support for vertical tabs, tab groups, and a unified search button in the address bar. The email client updates to Mozilla Thunderbird 140.6.0, and the Linux kernel moves to version 6.12.63 LTS from the Debian 13 “Trixie” repositories, incorporating upstream fixes and security enhancements.
Tails 7.4 also discontinues support for BitTorrent downloads. Citing the ecosystem's shift from BitTorrent v1 to v2 and the added maintenance burden, the project recommends direct downloads from official mirrors, which are typically faster.
Bug fixes address practical issues: improved handling of .gpg encrypted files in Kleopatra when double-clicked or opened via the menu; resolution of desktop crashes when unlocking VeraCrypt volumes with incorrect passwords; and consistent application of the 24-hour time format in the top navigation bar and lock screen.
Users on Tails 7.0, 7.1, 7.2, or 7.3.1 can upgrade automatically, though manual upgrades are advised if issues arise. Full details are in the release notes and changelog.
