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).

Release Notes: This release backports numerous high-priority fixes from the Tor 0.2.5 alpha release series. These include blocking all authority signing keys that may have been affected by the OpenSSL "heartbleed" bug, choosing a far more secure set of TLS ciphersuites by default, closing a couple of memory leaks that could be used to run a target relay out of RAM, and several others.
Release Notes: This release fixes potentially poor random number generation for users who use OpenSSL 1.0.0 or later, set "HardwareAccel 1" in their torrc file, have "Sandy Bridge" or "Ivy Bridge" Intel processors, and have no state file in their DataDirectory (as would happen on first start). Users who generated relay or hidden service identity keys in such a situation should discard them and generate new ones.
Release Notes: This release features a new circuit handshake and link encryption that use ECC to provide better security and efficiency; makes relays better manage circuit creation requests; uses "directory guards" to reduce client enumeration risks; makes bridges collect and report statistics about the pluggable transports they support; and cleans up and improves the geoip database. The release also includes many stability, security, and privacy fixes.
Release Notes: This release is the fourth release candidate for the Tor 0.2.4.x series. It takes a variety of fixes from the 0.2.5.x branch to improve stability, performance, and better handling of edge cases.
Release Notes: This release introduces experimental support for syscall sandboxing on Linux, allows bridges that offer pluggable transports to report usage statistics, fixes many issues to make testing easier, and provides a pile of minor features and bugfixes that have been waiting for a release of the new branch.
