Changes in version 0.2.1.13-alpha - 2009-03-09
Major bugfixes:

• Correctly update the list of which countries we exclude as
  exits, when the GeoIP file is loaded or reloaded. Diagnosed by
  lark. Bugfix on 0.2.1.6-alpha.

Minor bugfixes (on 0.2.0.x and earlier):

• Automatically detect MacOSX versions earlier than 10.4.0, and
  disable kqueue from inside Tor when running with these versions.
  We previously did this from the startup script, but that was no
  help to people who didn't use the startup script. Resolves bug 863.
• When we had picked an exit node for a connection, but marked it as
  "optional", and it turned out we had no onion key for the exit,
  stop wanting that exit and try again. This situation may not
  be possible now, but will probably become feasible with proposal
  158. Spotted by rovv. Fixes another case of bug 752.
• Clients no longer cache certificates for authorities they do not
  recognize. Bugfix on 0.2.0.9-alpha.
• When we can't transmit a DNS request due to a network error, retry
  it after a while, and eventually transmit a failing response to
  the RESOLVED cell. Bugfix on 0.1.2.5-alpha.
• If the controller claimed responsibility for a stream, but that
  stream never finished making its connection, it would live
  forever in circuit_wait state. Now we close it after SocksTimeout
  seconds. Bugfix on 0.1.2.7-alpha; reported by Mike Perry.
• Drop begin cells to a hidden service if they come from the middle
  of a circuit. Patch from lark.
• When we erroneously receive two EXTEND cells for the same circuit
  ID on the same connection, drop the second. Patch from lark.
• Fix a crash that occurs on exit nodes when a nameserver request
  timed out. Bugfix on 0.1.2.1-alpha; our CLEAR debugging code had
  been suppressing the bug since 0.1.2.10-alpha. Partial fix for
  bug 929.
• Do not assume that a stack-allocated character array will be
  64-bit aligned on platforms that demand that uint64_t access is
  aligned. Possible fix for bug 604.
• Parse dates and IPv4 addresses in a locale- and libc-independent
  manner, to avoid platform-dependent behavior on malformed input.
• Build correctly when configured to build outside the main source
  path. Patch from Michael Gold.
• We were already rejecting relay begin cells with destination port
  of 0. Now also reject extend cells with destination port or address
  of 0. Suggested by lark.

Minor bugfixes (on 0.2.1.x):

• Don't re-extend introduction circuits if we ran out of RELAY_EARLY
  cells. Bugfix on 0.2.1.3-alpha. Fixes more of bug 878.
• If we're an exit node, scrub the IP address to which we are exiting
  in the logs. Bugfix on 0.2.1.8-alpha.

Minor features:

• On Linux, use the prctl call to re-enable core dumps when the user
  is option is set.
• New controller event NEWCONSENSUS that lists the networkstatus
  lines for every recommended relay. Now controllers like Torflow
  can keep up-to-date on which relays they should be using.
• Update to the "February 26 2009" ip-to-country file.
