WALPOLE, MA The Tor Project announces a new stable release of the Tor software. More than two years in the making, this release features improved client performance and hidden service reliability, better compatibility for Android, correct behavior for bridges that listen on more than one address, more extensible and flexible directory object handling, better reporting of network statistics, improved code security, and many many other features and bugfixes. A full changelog is available.

This release series is dedicated to the memory of Andreas Pfitzmann (1958-2010), a pioneer in anonymity and privacy research, a founder of the PETS community, a leader in our field, a mentor, and a friend. He left us with these words:

"I had the possibility to contribute to this world that is not as it should be. I hope I could help in some areas to make the world a better place, and that I could also encourage other people to be engaged in improving the world. Please, stay engaged. This world needs you, your love, your initiative -- now I cannot be part of that anymore."

Tor's tools and technologies are already used by millions of people to protect their activities online. These users include journalists and human rights workers in politically rigid countries communicating with whistleblowers and dissidents. Law enforcement officers on Internet sting operations stay anonymous with Tor, as do people wanting to post socially sensitive information in chat rooms, like rape or abuse survivors and those with illnesses.  The Tor network also provides protection for people looking for another layer of privacy from the millions of websites and ISPs bent on collecting private information and tracking their moves online.

Pre-compiled and configured versions of Tor can be found on the download page.


Based in Walpole, MA, The Tor Project develops free and open-source software that provides online anonymity to the everyday Internet user. Tor was born out of a collaboration with the U.S. Naval Research Lab starting in 2001, and it became an official U.S. 501(c)(3) non-profit in 2006. The Tor Project now works with many individuals, NGOs, law enforcement agencies, and businesses globally to help them protect their anonymity online.

In addition to its efforts developing and maintaining the Tor anonymity software and the Tor network, The Tor Project also helps to lead the research community in understanding how to build and measure scalable and secure anonymity networks. The Tor developers publish several new research papers each year in major academic security conferences, and just about every major security conference these days includes a Tor-related paper. Tor is a project-funded organization with a staff of 15.
