forward-port the 0.2.3.19-rc changelog

Changes in version 0.2.3.19-rc - 2012-07-06

  Tor 0.2.3.19-rc is the second release candidate for the Tor 0.2.3.x

  series. It fixes the compile on Windows, reverts to a GeoIP database

  that isn't as broken, and fixes a flow control bug that has been around

  since the beginning of Tor.

  o Major bugfixes:

    - Fix a bug handling SENDME cells on nonexistent streams that could

      result in bizarre window values. Report and patch contributed

      pseudonymously. Fixes part of bug 6271. This bug was introduced

      before the first Tor release, in svn commit r152.

    - Revert to the May 1 2012 Maxmind GeoLite Country database. In the

      June 2012 database, Maxmind marked many Tor relays as country "A1",

      which will cause risky behavior for clients that set EntryNodes

      or ExitNodes. Addresses bug 6334; bugfix on 0.2.3.17-beta.

    - Instead of ENOBUFS on Windows, say WSAENOBUFS. Fixes compilation

      on Windows. Fixes bug 6296; bugfix on 0.2.3.18-rc.

  o Minor bugfixes:

    - Fix wrong TCP port range in parse_port_range(). Fixes bug 6218;

      bugfix on 0.2.1.10-alpha.
