To Tails Project just released the final live OS Tails 3.0, a live operating system that runs on any computer and leaves no trace to either the machine or the internet.
This particular functional Tails was used by former NSA employee Edward Snowden to remain hidden on the internet.
If you want to help develop the Tails Project, the first RC for the upcoming 3.0 version has just been released and is available for testing.
How can you help? Of course, mentioning the bugs you encounter with the developers of the project.
The Tails 3.0 will be the first release of Debian 9 (Stretch) based Tails and will feature GNOME Shell 3.22 as a preferred desktop:
"Tails 3.0 works only on 64-bit computers and no longer on 32-bit systems. To protect against security exploits, support for NX bit became obligatory and most binaries became hardened with PIE allowing ASLR. Tor Browser was upgraded to the 7.0 version (based on Firefox 52 ESR), which uses multi-process and sandboxing. »
Upgraded Tor Browser 7.0, KeePassX 2.0.3, LibreOffice 5.2.6, Inkscape 0.92.1, Audacity 2.1.2, Enigmail 1.9.6, MAT 0.6.1, Dasher 5.0, and Git 2.11.0
