+Changes in version 0.2.1.27 - 2010-11-23
+  Yet another OpenSSL security patch broke its compatibility with Tor:
+  Tor 0.2.1.27 makes relays work with openssl 0.9.8p and 1.0.0.b. We
+  also took this opportunity to fix several crash bugs, integrate a new
+  directory authority, and update the bundled GeoIP database.
+
+  o Major bugfixes:
+    - Resolve an incompatibility with OpenSSL 0.9.8p and OpenSSL 1.0.0b:
+      No longer set the tlsext_host_name extension on server SSL objects;
+      but continue to set it on client SSL objects. Our goal in setting
+      it was to imitate a browser, not a vhosting server. Fixes bug 2204;
+      bugfix on 0.2.1.1-alpha.
+    - Do not log messages to the controller while shrinking buffer
+      freelists. Doing so would sometimes make the controller connection
+      try to allocate a buffer chunk, which would mess up the internals
+      of the freelist and cause an assertion failure. Fixes bug 1125;
+      fixed by Robert Ransom. Bugfix on 0.2.0.16-alpha.
+    - Learn our external IP address when we're a relay or bridge, even if
+      we set PublishServerDescriptor to 0. Bugfix on 0.2.0.3-alpha,
+      where we introduced bridge relays that don't need to publish to
+      be useful. Fixes bug 2050.
+    - Do even more to reject (and not just ignore) annotations on
+      router descriptors received anywhere but from the cache. Previously
+      we would ignore such annotations at first, but cache them to disk
+      anyway. Bugfix on 0.2.0.8-alpha. Found by piebeer.
+    - When you're using bridges and your network goes away and your
+      bridges get marked as down, recover when you attempt a new socks
+      connection (if the network is back), rather than waiting up to an
+      hour to try fetching new descriptors for your bridges. Bugfix on
+      0.2.0.3-alpha; fixes bug 1981.
+
+  o Major features:
+    - Move to the November 2010 Maxmind GeoLite country db (rather
+      than the June 2009 ip-to-country GeoIP db) for our statistics that
+      count how many users relays are seeing from each country. Now we'll
+      have more accurate data, especially for many African countries.
+
+  o New directory authorities:
+    - Set up maatuska (run by Linus Nordberg) as the eighth v3 directory
+      authority.
+
+  o Minor bugfixes:
+    - Fix an assertion failure that could occur in directory caches or
+      bridge users when using a very short voting interval on a testing
+      network. Diagnosed by Robert Hogan. Fixes bug 1141; bugfix on
+      0.2.0.8-alpha.
+    - Enforce multiplicity rules when parsing annotations. Bugfix on
+      0.2.0.8-alpha. Found by piebeer.
+    - Allow handshaking OR connections to take a full KeepalivePeriod
+      seconds to handshake. Previously, we would close them after
+      IDLE_OR_CONN_TIMEOUT (180) seconds, the same timeout as if they
+      were open. Bugfix on 0.2.1.26; fixes bug 1840. Thanks to mingw-san
+      for analysis help.
+    - When building with --enable-gcc-warnings on OpenBSD, disable
+      warnings in system headers. This makes --enable-gcc-warnings
+      pass on OpenBSD 4.8.
+
+  o Minor features:
+    - Exit nodes didn't recognize EHOSTUNREACH as a plausible error code,
+      and so sent back END_STREAM_REASON_MISC. Clients now recognize a new
+      stream ending reason for this case: END_STREAM_REASON_NOROUTE.
+      Servers can start sending this code when enough clients recognize
+      it. Bugfix on 0.1.0.1-rc; fixes part of bug 1793.
+    - Build correctly on mingw with more recent versions of OpenSSL 0.9.8.
+      Patch from mingw-san.
+
+  o Removed files:
+    - Remove the old debian/ directory from the main Tor distribution.
+      The official Tor-for-debian git repository lives at the URL
+      https://git.torproject.org/debian/tor.git
+    - Stop shipping the old doc/website/ directory in the tarball. We
+      changed the website format in late 2010, and what we shipped in
+      0.2.1.26 really wasn't that useful anyway.

 Changes in version 0.2.1.26 - 2010-05-02
   Tor 0.2.1.26 addresses the recent connection and memory overload
   problems we've been seeing on relays, especially relays with their
