All of its outgoing connections are routed through Tor, and it even blocks non-anonymous connections. You can carry it around on a USB stick, and Edward Snowden uses it. But a big change is coming with Tails 3.0. BrianFagioli quotes BetaNews: Unfortunately for some users, Tails will soon not work on their computers. The upcoming version 3.0 of the operating system is dropping 32-bit processor support. While a decline in compatibility is normally a bad thing, in this case, it is good. You see, because there are so few 32-bit Tails users, the team was wasting resources by supporting them. Not to mention, 64-bit processors are more secure too… “In the beginning of 2016, only 4% of Tails users were still using a 32-bit computer. Of course, some of these computers will keep working for a while. But once the number had fallen this low, the benefits of switching Tails to 64-bit outweighed the reasons we had to keep supporting 32-bit computers, ” says the Tails team… “In the last few years, the developers who maintain Tails have spent lots of time addressing such issues. We would rather see them spend their time in ways that benefit our users on the long term, and not on problems that will vanish when Tails switches to 64-bit eventually.” Read more of this story at Slashdot.
