Tails 4.0 Anonymous Linux OS Released

Tails is a live system that aims to preserve your privacy and anonymity. It helps you to use the Internet anonymously and circumvent censorship almost anywhere you go and on any computer but leaving no trace unless you ask it to explicitly.

It is a complete operating system designed to be used from a USB stick or a DVD independently of the computer’s original operating system. It is Free Software and based on Debian GNU/Linux.

Tails comes with several built-in applications pre-configured with security in mind: web browser, instant messaging client, email client, office suite, image and sound editor, etc.

Tails brings new 4.0 version of most of the software included in Tails and some important usability and performance improvements. Tails 4.0 introduces more changes than any other version since years.

Changes and Upgrade

  • Replace KeePassX with KeePassXC, which is more actively developed.
  • Update Tor Browser to 9.0:
  • Update MAT from 0.6.1 to 0.8.0
  • Update Electrum from 3.2.3 to 3.3.8. Electrum works again in Tails.
  • Update Enigmail to 2.0.12 and gnupg to 2.2.12, which mitigate OpenPGP certificate flooding.

MAT has no graphical interface of its own anymore.

  3. Right-click (on Mac, click with two fingers) on the file.
  4. Choose Remove metadata.

Remove Scribus

You can install Scribus again using the Additional Software feature.

Usability improvements to Tails Greeter

The new version has improved various aspects of the usability of Tails Greeter, especially for non-English users:

To make it easier to select a language, we curated the list of proposed languages by removing the ones that had too little translations to be useful. We also clarified how Chinese is listed by having different entries for simplified and traditional Chinese.

  • It simplified the list of keyboard layouts.
  • It fixed the Formats setting, which was not being applied.
  • It prevented additional settings to be applied when clicking on Cancel or Back.
  • It fixed the opening of help pages in other languages than English, when available.

Performance and usability improvements

  • Tails 4.0 starts 20 percent faster.
  • Tails 4.0 requires about 250 MB less of RAM.
  • Tails 4.0 is 47 MB smaller to download than Tails 3.16, despite all these changes.
  • Add support for Thunderbolt devices.
  • The screen keyboard is easier to use.
