Relays + now close idle circuits early if it looks like they were intended + for directory fetches. Relays are also more aggressive about closing + TLS connections that have no circuits on them. Such circuits are + unlikely to be re-used, and tens of thousands of them were piling + up at the fast relays, causing the relays to run out of sockets + and memory. Bugfix on 0.2.0.22-rc (where clients started tunneling + their directory fetches over TLS). + + o Minor features: + - Finally get rid of the deprecated and now harmful notion of "clique + mode", where directory authorities maintain TLS connections to + every other relay. + - Directory authorities now do an immediate reachability check as soon + as they hear about a new relay. This change should slightly reduce + the time between setting up a relay and getting listed as running + in the consensus. It should also improve the time between setting + up a bridge and seeing use by bridge users. + - Directory authorities no longer launch a TLS connection to every + relay as they startup. Now that we have 2k+ descriptors cached, + the resulting network hiccup is becoming a burden. Besides, + authorities already avoid voting about Running for the first half + hour of their uptime. + + +Changes in version 0.2.2.12-alpha - 2010-04-20 + Tor 0.2.2.12-alpha fixes a critical bug in how directory authorities + handle and vote on descriptors. It was causing relays to drop out of + the consensus. + + o Major bugfixes: + - Many relays have been falling out of the consensus lately because + not enough authorities know about their descriptor for them to get + a majority of votes. When we deprecated the v2 directory protocol, + we got rid of the only way that v3 authorities can hear from each + other about other descriptors. Now authorities examine every v3 + vote for new descriptors, and fetch them from that authority. Bugfix + on 0.2.1.23. + - Fix two typos in tor_vasprintf() that broke the compile on Windows, + and a warning in or.h related to bandwidth_weight_rule_t that + prevented clean compile on OS X. Fixes bug 1363; bugfix on + 0.2.2.11-alpha. + - Fix a segfault on relays when DirReqStatistics is enabled + and 24 hours pass. Bug found by keb. Fixes bug 1365; bugfix on + 0.2.2.11-alpha. + + o Minor bugfixes: + - Demote a confusing TLS warning that relay operators might get when + someone tries to talk to their OrPort. It is neither the operator's + fault nor can they do anything about it. Fixes bug 1364; bugfix + on 0.2.0.14-alpha. + + +Changes in version 0.2.2.11-alpha - 2010-04-15 + Tor 0.2.2.11-alpha fixes yet another instance of broken OpenSSL + libraries that was causing some relays to drop out of the consensus. + + o Major bugfixes: + - Directory mirrors were fetching relay descriptors only from v2 + directory authorities, rather than v3 authorities like they should. + Only 2 v2 authorities remain (compared to 7 v3 authorities), leading + to a serious bottleneck. Bugfix on 0.2.0.9-alpha. Fixes bug 1324. + - Fix a parsing error that made every possible value of + CircPriorityHalflifeMsec get treated as "1 msec". Bugfix + on 0.2.2.7-alpha. Rename CircPriorityHalflifeMsec to + CircuitPriorityHalflifeMsec, so authorities can tell newer relays + about the option without breaking older ones. + - Fix SSL renegotiation behavior on OpenSSL versions like on Centos + that claim to be earlier than 0.9.8m, but which have in reality + backported huge swaths of 0.9.8m or 0.9.8n renegotiation + behavior. Possible fix for some cases of bug 1346. + o Minor features: - Experiment with a more aggressive approach to preventing clients from making one-hop exit streams. Exit relays who want to try it out can set "RefuseUnknownExits 1" in their torrc, and then look for "Attempt by %s to open a stream" log messages. Let us know how it goes! + - Add support for statically linking zlib by specifying + --enable-static-zlib, to go with our support for statically linking + openssl and libevent. Resolves bug 1358. o Minor bugfixes: + - Fix a segfault that happens whenever a Tor client that is using + libevent2's bufferevents gets a hup signal. Bugfix on 0.2.2.5-alpha; + fixes bug 1341. - When we cleaned up the contrib/tor-exit-notice.html file, we left out the first line.

Bugfix on 0.2.1.6-alpha. + - The master thread could starve the worker threads quite badly on + certain systems, causing them to run only partially in the allowed + window.
