 Changes in version 0.2.1.20 - 2009-10-15
+  Tor 0.2.1.20 fixes a crash bug when you're accessing many hidden
+  services at once, prepares for more performance improvements, and
+  fixes a bunch of smaller bugs.
+
+  The Windows and OS X bundles also include a more recent Vidalia,

+  The OS X installers are now drag and drop. It's best to un-install
+  Tor/Vidalia and then install this new bundle, rather than upgrade. If
+  you want to upgrade, you'll need to update the paths for Tor and Polipo
+  in the Vidalia Settings window.

   o Major bugfixes:
     - Send circuit or stream sendme cells when our window has decreased
       by 100 cells, not when it has decreased by 101 cells. Bug uncovered

+Changes in version 0.2.1.20 - 2009-10-15
+  Tor 0.2.1.20 fixes a crash bug when you're accessing many hidden
+  services at once, prepares for more performance improvements, and
+  fixes a bunch of smaller bugs.
+
+  The Windows and OS X bundles also include a more recent Vidalia,
+  and switch from Privoxy to Polipo.
+
+  The OS X installers are now drag and drop. It's best to un-install
+  Tor/Vidalia and then install this new bundle, rather than upgrade. If
+  you want to upgrade, you'll need to update the paths for Tor and Polipo
+  in the Vidalia Settings window.
+
+  o Major bugfixes:
+    - Send circuit or stream sendme cells when our window has decreased
+      by 100 cells, not when it has decreased by 101 cells. Bug uncovered
+      by Karsten when testing the "reduce circuit window" performance
+      patch. Bugfix on the 54th commit on Tor -- from July 2002,
+      before the release of Tor 0.0.0. This is the new winner of the
+      oldest-bug prize.
+    - Fix a remotely triggerable memory leak when a consensus document
+      contains more than one signature from the same voter. Bugfix on
+      0.2.0.3-alpha.
+    - Avoid segfault in rare cases when finishing an introduction circuit
+      as a client and finding out that we don't have an introduction key
+      for it. Fixes bug 1073. Reported by Aaron Swartz.
+
+  o Major features:
+    - Tor now reads the "circwindow" parameter out of the consensus,
+      and uses that value for its circuit package window rather than the
+      default of 1000 cells. Begins the implementation of proposal 168.
+
+  o New directory authorities:
+    - Set up urras (run by Jacob Appelbaum) as the seventh v3 directory
+      authority.
+    - Move moria1 and tonga to alternate IP addresses.
+
+  o Minor bugfixes:
+    - Fix a signed/unsigned compile warning in 0.2.1.19.
+    - Fix possible segmentation fault on directory authorities. Bugfix on
+      0.2.1.14-rc.
+    - Fix an extremely rare infinite recursion bug that could occur if
+      we tried to log a message after shutting down the log subsystem.
+      Found by Matt Edman. Bugfix on 0.2.0.16-alpha.
+    - Fix an obscure bug where hidden services on 64-bit big-endian
+      systems might mis-read the timestamp in v3 introduce cells, and
+      refuse to connect back to the client. Discovered by "rotor".
+      Bugfix on 0.2.1.6-alpha.
+    - We were triggering a CLOCK_SKEW controller status event whenever
+      we connect via the v2 connection protocol to any relay that has
+      a wrong clock. Instead, we should only inform the controller when
+      it's a trusted authority that claims our clock is wrong. Bugfix
+      on 0.2.0.20-rc; starts to fix bug 1074. Reported by SwissTorExit.
+    - We were telling the controller about CHECKING_REACHABILITY and
+      REACHABILITY_FAILED status events whenever we launch a testing
+      circuit or notice that one has failed. Instead, only tell the
+      controller when we want to inform the user of overall success or
+      overall failure. Bugfix on 0.1.2.6-alpha. Fixes bug 1075. Reported
+      by SwissTorExit.
+    - Don't warn when we're using a circuit that ends with a node
+      excluded in ExcludeExitNodes, but the circuit is not used to access
+      the outside world. This should help fix bug 1090. Bugfix on
+      0.2.1.6-alpha.
+    - Work around a small memory leak in some versions of OpenSSL that
+      stopped the memory used by the hostname TLS extension from being
+      freed.
+
+  o Minor features:
+    - Add a "getinfo status/accepted-server-descriptor" controller
+      command, which is the recommended way for controllers to learn
+      whether our server descriptor has been successfully received by at
+      least on directory authority. Un-recommend good-server-descriptor
+      getinfo and status events until we have a better design for them.
