Tails is a live operating system, that you can start on almost any computer from a DVD, USB stick, or SD card. It aims at preserving your privacy and anonymity, and helps you to:
- use the Internet anonymously and circumvent censorship;all connections to the Internet are forced to go through the Tor network;
- leave no trace on the computer you are using unless you ask it explicitly;
- use state-of-the-art cryptographic tools to encrypt your files, emails and instant messaging.
Changes
Notable user-visible changes include:
- Security fixes
- Upgrade the web browser to 24.8.0esr-0+tails1~bpo70+1 (Firefox 24.8.0esr + Iceweasel patches + Torbrowser patches).
- Add an I2P boot parameter. Without adding "i2p" to the kernel command line, I2P will not be accessible for the Live user. I2P was also upgraded to 0.9.14.1-1~deb7u+1, and stricter firewall rules are applied to it, among other security enhancements.

- Prevent dhclient from sending the hostname over the network (ticket #7688).
- Override the hostname provided by the DHCP server (ticket #7769).
