Changes in version 0.2.1.8-alpha - 2008-12-08
Major features:

• New DirPortFrontPage option that takes an html file and publishes
  it as "/" on the DirPort. Now relay operators can provide a
  disclaimer without needing to set up a separate webserver. There's
  a sample disclaimer in contrib/tor-exit-notice.html.

Security fixes:

• When the client is choosing entry guards, now it selects at most
  one guard from a given relay family. Otherwise we could end up with
  all of our entry points into the network run by the same operator.
  Suggested by Camilo Viecco. Fix on 0.1.1.11-alpha.

Major bugfixes:

• Fix a DOS opportunity during the voting signature collection process
  at directory authorities. Spotted by rovv. Bugfix on 0.2.0.x.
• Fix a possible segfault when establishing an exit connection. Bugfix
  on 0.2.1.5-alpha.

Minor bugfixes:

• Get file locking working on win32. Bugfix on 0.2.1.6-alpha. Fixes
  bug 859.
• Made Tor a little less aggressive about deleting expired
  certificates. Partial fix for bug 854.
• Stop doing unaligned memory access that generated bus errors on
  sparc64. Bugfix on 0.2.0.10-alpha. Fix for bug 862.
• Fix a crash bug when changing EntryNodes from the controller. Bugfix
  on 0.2.1.6-alpha. Fix for bug 867. Patched by Sebastian.
• Make USR2 log-level switch take effect immediately. Bugfix on
  0.1.2.8-beta.
• If one win32 nameserver fails to get added, continue adding the
  rest, and don't automatically fail.
• Use fcntl() for locking when flock() is not available. Should fix
  compilation on Solaris. Should fix Bug 873. Bugfix on 0.2.1.6-alpha.
• Do not mark smartlist_bsearch_idx() function as ATTR_PURE. This bug
  could make gcc generate non-functional binary search code. Bugfix
  on 0.2.0.10-alpha.
• Build correctly on platforms without socklen_t.
• Avoid potential crash on internal error during signature collection.
  Fixes bug 864. Patch from rovv.
• Do not use C's stdio library for writing to log files. This will
  improve logging performance by a minute amount, and will stop
  leaking fds when our disk is full. Fixes bug 861.
• Stop erroneous use of O_APPEND in cases where we did not in fact
  want to re-seek to the end of a file before every last write().
• Correct handling of possible malformed authority signing key
  certificates with internal signature types. Fixes bug 880. Bugfix
  on 0.2.0.3-alpha.
• Fix a hard-to-trigger resource leak when logging credential status.
  CID 349.

Minor features:

• Directory mirrors no longer fetch the v1 directory or
  running-routers files. They are obsolete, and nobody asks for them
  anymore. This is the first step to making v1 authorities obsolete.

Minor features (controller):

Return circuit purposes in response to GETINFO circuit-status. Fixes
bug 858.
