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).
Changes: Tor 0.3.3.6 is the first stable release in the 0.3.3 series. It backports several important fixes from the 0.3.4.1-alpha. The Tor 0.3.3 series includes controller support and other improvements for v3 onion services, official support for embedding Tor within other applications, and our first non-trivial module written in the Rust programming language. (Rust is still not enabled by default when building Tor.) And as usual, there are numerous other smaller bugfixes, features, and improvements.
