connection", to simplify the code and make exit connections smaller.
+Changes in version 0.2.2.33 - 2011-09-13
+ Tor 0.2.2.33 fixes several bugs, and includes a slight tweak to Tor's
+ TLS handshake that makes relays and bridges that run this new version
+ reachable from Iran again.
+
+ o Major bugfixes:
+ - Avoid an assertion failure when reloading a configuration with
+ TrackExitHosts changes. Found and fixed by 'laruldan'. Fixes bug
+ 3923; bugfix on 0.2.2.25-alpha.
+
+ o Minor features (security):
+ - Check for replays of the public-key encrypted portion of an
+ INTRODUCE1 cell, in addition to the current check for replays of
+ the g^x value. This prevents a possible class of active attacks
+ by an attacker who controls both an introduction point and a
+ rendezvous point, and who uses the malleability of AES-CTR to
+ alter the encrypted g^x portion of the INTRODUCE1 cell. We think
+ that these attacks are infeasible (requiring the attacker to send
+ on the order of zettabytes of altered cells in a short interval),
+ but we'd rather block them off in case there are any classes of
+ this attack that we missed. Reported by Willem Pinckaers.
+
+ o Minor features:
+ - Adjust the expiration time on our SSL session certificates to
+ better match SSL certs seen in the wild. Resolves ticket 4014.
+ - Change the default required uptime for a relay to be accepted as
+ a HSDir (hidden service directory) from 24 hours to 25 hours.
+ Improves on 0.2.0.10-alpha; resolves ticket 2649.
+ - Add a VoteOnHidServDirectoriesV2 config option to allow directory
+ authorities to abstain from voting on assignment of the HSDir
+ consensus flag. Related to bug 2649.
+ - Update to the September 6 2011 Maxmind GeoLite Country database.
+
+ o Minor bugfixes (documentation and log messages):
+ - Correct the man page to explain that HashedControlPassword and
+ CookieAuthentication can both be set, in which case either method
+ is sufficient to authenticate to Tor. Bugfix on 0.2.0.7-alpha,
+ when we decided to allow these config options to both be set. Issue
+ raised by bug 3898.
+ - Demote the 'replay detected' log message emitted when a hidden
+ service receives the same Diffie-Hellman public key in two different
+ INTRODUCE2 cells to info level. A normal Tor client can cause that
+ log message during its normal operation. Bugfix on 0.2.1.6-alpha;
+ fixes part of bug 2442.
+ - Demote the 'INTRODUCE2 cell is too {old,new}' log message to info
+ level. There is nothing that a hidden service's operator can do
+ to fix its clients' clocks. Bugfix on 0.2.1.6-alpha; fixes part
+ of bug 2442.
+ - Clarify a log message specifying the characters permitted in
+ HiddenServiceAuthorizeClient client names. Previously, the log
+ message said that "[A-Za-z0-9+-_]" were permitted; that could have
+ given the impression that every ASCII character between "+" and "_"
+ was permitted. Now we say "[A-Za-z0-9+_-]". Bugfix on 0.2.1.5-alpha.
+
+ o Build fixes:
+ - Provide a substitute implementation of lround() for MSVC, which
+ apparently lacks it. Patch from Gisle Vanem.
+ - Clean up some code issues that prevented Tor from building on older
+ BSDs. Fixes bug 3894; reported by "grarpamp".
+ - Search for a platform-specific version of "ar" when cross-compiling.
+ Should fix builds on iOS. Resolves bug 3909, found by Marco Bonetti.
