This release fixes many security issues and users should upgrade as soon as possible.

In particular, Tails 3.4 fixes the widely reported Meltdown attack, and includes the partial mitigation for Spectre.


Upgrades and changes

Fixed problems

  • Fix an issue that made Tails start very slowly, in particular on DVD. (#14964)

  • Don't delete downloaded Debian packages after installing them. This is mostly relevant for users of the APT Packages persistence feature. (#10958)

  • Fix an issue that prevented some Debian packages to install properly with the Additional software feature. (#6038)

  • Update uBlock Origin to restore its icon in Tor Browser, and make its settings dashboard work again. (#14993)

For more details, read our changelog.

Known issues

  • The graphical splash screen usually displayed during Tails startup quickly disappears and is replaced by garbled text messages. As long as Tails appears to work fine for you otherwise, please ignore these messages, including the alarming message about a "kernel BUG" (which was reported to Debian): they do not affect the safety of your Tails system.
  • Due to an issue in Tor Browser, the documentation shipped in Tails doesn't open in Tor Browser anymore and lacks our sidebar. The warning page of the Unsafe Browser also lacks graphical design. (#14962)
