Release Notes: This release introduces a feature to make it harder for clients to use one-hop circuits (which can put the exit relays at higher risk, plus unbalance the network). A big bug was fixed in bandwidth accounting for relays that want to limit their monthly bandwidth use. A big pile of bugs in how clients tolerate temporary network failure was fixed. The adaptive circuit build timeout feature (which improves client performance if your network is fast while not breaking things if your network is slow) now handles bad networks better.
Release Notes: This release addresses the recent connection and memory overload problems encountered on relays, especially relays with their DirPort open. If your relay has been crashing, or if you turned it off because it used too many resources, this release may help. This release also fixes yet another instance of broken OpenSSL libraries that was causing some relays to drop out of the consensus.
Release Notes: This release fixes a critical bug in how directory authorities handle and vote on descriptors. It was causing relays to drop out of the consensus.
Release Notes: This release fixes a regression introduced in 0.2.1.23 that could prevent relays from guessing their IP address correctly. It also fixes several minor potential security bugs.
Release Notes: This release makes Tor work again on the latest version of Mac OS X, and updates the location of a directory authority. It also fixes a regression introduced in 0.2.2.9-alpha that could prevent relays from guessing their IP address correctly. It also starts the groundwork for another client-side performance boost, since relays that have both the Guard flag and the Exit flag are not being used efficiently.
Release Notes: This release fixes a huge client-side performance bug, makes Tor work again on the latest Mac OS X, and updates the location of a directory authority.
Release Notes: This release fixes a crash bug in 0.2.2.7-alpha that has been causing bridge relays to disappear. If you're running a bridge, you should upgrade.
Release Notes: This release fixes a huge client-side performance bug, as well as laying the groundwork for further relay-side performance fixes. It also starts cleaning up client behavior with respect to the EntryNodes, ExitNodes, and StrictNodes configuration options.
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 an incompatibility with the most recent OpenSSL library. If you use Tor on Linux or Unix and you're getting SSL renegotiation errors, upgrading should help. An upgrade is also recommended if you're an exit relay.
