Changes

New features

  • We enabled address space layout randomization in the Linux kernel (kASLR) to improve protection from buffer overflow attacks.
  • We installed rngd to improve the entropy of the random numbers generated on computers that have a hardware random number generator.

Upgrades and changes

  • Upgrade Tor to 0.2.8.7.
  • Upgrade Tor Browser to 6.0.5.
  • Upgrade to Linux 4.6. This should improve the support for newer hardware (graphics, Wi-Fi, etc.)
  • Upgrade Icedove to 45.2.0.
  • Upgrade Tor Birdy to 0.2.0.
  • Upgrade Electrum to 2.6.4.
  • Install firmware for Intel SST sound cards (firmware-intel-sound).
  • Install firmware for Texas Instruments Wi-Fi interfaces (firmware-ti-connectivity).
  • Remove non-free APT repositories. We documented how to configure additional APT repositories using the persistent volume.
  • Use a dedicated page as the homepage of Tor Browser so we can customize it for our users.
  • Set up the trigger for RAM erasure on shutdown earlier in the boot process. This should speed up shutdown and make RAM erasure more robust.

Fixed problems

  • Disable the automatic configuration of Icedove when using OAuth. This should fix the automatic configuration for GMail accounts. (#11536)
  • Make the Disable all networking and Tor bridge mode options of Tails Greeter more robust. (#11593)
For more details, read our changelog.

Known issues

  • For some users memory wiping fails more often than in Tails 2.5, and for some users it fails less often. Please report any such changes to #11786.
See the list of long-standing issues.
