Tails 4.0 - Live System to Preserve Your Privacy and Anonymity


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 DVD, USB stick, or SD card independently of the computer's original operating system.

Changes


  • Replace KeePassX with KeePassXC, which is more actively developed.



  • Update OnionShare from 0.9.2 to 1.3.2, which includes a lot of usability improvements.




  • Update Tor Browser to 9.0:
    • A gray border, called letter boxing, is now displayed around the content of web pages when you resize the window of Tor Browser.


Letter boxing prevents websites from identifying your browser based on the size of its window. Letter boxing replaces the yellow warning that was displayed until now when maximizing Tor Browser.

    • The onion icon has been removed from the top bar.

To switch to a new identity, choose ▸ New Identity.


  • Update MAT from 0.6.1 to 0.8.0

MAT has no graphical interface of its own anymore.
To clean the metadata of a file:


  1. Open the Files browser and navigate to the file that you want to clean.
  2. Right-click (on Mac, click with two fingers) on the file.
  3. Choose Remove metadata.



  • Update Linux to 5.3.2. This should also improve the support for newer hardware (graphics, Wi-Fi, etc.).
  • 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.
  • Upgrade most other software, for example:
    • Audacity from 2.1.2 to 2.2.2
    • GIMP from 2.8.18 to 2.10.8
    • Inkscape from 0.92.1 to 0.92.4
    • LibreOffice from 5.2.7 to 6.1.5
    • git from 2.11.0 to 2.20.1
    • Tor to 0.4.1.6
  • Remove Scribus.
You can install Scribus again using the Additional Software feature.
