Release Notes: This release rotates two of the seven v3 directory authority keys and locations, due to a security breach of some of the Tor project servers. It also fixes a privacy problem in bridge directory authorities in which it would tell you its whole history of bridge descriptors if you made the right directory request.
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.
Release Notes: This is the second release candidate for the Tor 0.2.4.x series. It fixes several crash bugs in the 0.2.4 branch.
