Tor

Tor is a network of virtual tunnels that allows people and groups to improve their privacy and security on the Internet. It also enables software developers to create new communication tools with built-in privacy features. It provides the foundation for a range of applications that allow organizations and individuals to share information over public networks without compromising their privacy. Individuals can use it to keep remote Websites from tracking them and their family members. They can also use it to connect to resources such as news sites or instant messaging services that are blocked by their local Internet service providers (ISPs).

Recent releases

0.2.3.15-alpha

01 May 2012 10:13

Release Notes: This release fixes a variety of smaller bugs. The development branch now builds on Windows again.

0.2.3.14-alpha

24 Apr 2012 21:04

Release Notes: This release fixes yet more bugs to get closer to a release candidate. It also dramatically speeds up AES: fast relays should consider switching to the newer OpenSSL library.

0.2.3.12-alpha

14 Feb 2012 22:20

Release Notes: This release lets fast exit relays scale better, allows clients to use bridges that run Tor 0.2.2.x, and resolves several big bugs when Tor is configured to use a pluggable transport like obfsproxy.

0.2.2.35

17 Dec 2011 09:13

Release Notes: This release fixes a critical heap overflow security issue in Tor's buffers code. Absolutely everybody should upgrade. The bug relied on an incorrect calculation when making data continuous in one of the IO buffers, if the first chunk of the buffer was misaligned by just the wrong amount. The miscalculation would allow an attacker to overflow a piece of heap-allocated memory.

0.2.3.8-alpha

25 Nov 2011 20:16

Release Notes: This release fixes some crash and assert bugs, including a socketpair-related bug which has been bothering Windows users. It adds support to serve microdescriptors to controllers, so Vidalia's network map can resume listing relays (once Vidalia implements its side) and adds better support for hardware AES acceleration. Finally, it starts the process of adjusting the bandwidth cutoff for getting the "Fast" flag from 20KB to (currently) 32KB. Preliminary results show that tiny relays harm performance more than they help network capacity.
