+Changes in version 0.2.1.23 - 2010-02-12
+  o Major bugfixes (performance):
+    - We were selecting our guards uniformly at random, and then weighting
+      which of our guards we'd use uniformly at random. This imbalance
+      meant that Tor clients were severely limited on throughput (and
+      probably latency too) by the first hop in their circuit. Now we
+      select guards weighted by currently advertised bandwidth. We also
+      automatically discard guards picked using the old algorithm. Fixes
+      bug 1217; bugfix on 0.2.1.3-alpha. Found by Mike Perry.
+
+  o Major bugfixes:
+    - Make Tor work again on the latest OS X: when deciding whether to
+      use strange flags to turn TLS renegotiation on, detect the OpenSSL
+      version at run-time, not compile time. We need to do this because
+      Apple doesn't update its dev-tools headers when it updates its
+      libraries in a security patch.
+    - Fix a potential buffer overflow in lookup_last_hid_serv_request()
+      that could happen on 32-bit platforms with 64-bit time_t. Also fix
+      a memory leak when requesting a hidden service descriptor we've
+      requested before. Fixes bug 1242, bugfix on 0.2.0.18-alpha. Found
+      by aakova.
+
+  o Minor bugfixes:
+    - Refactor resolve_my_address() to not use gethostbyname() anymore.
+      Fixes bug 1244; bugfix on 0.0.2pre25. Reported by Mike Mestnik.
+
+  o Minor features:
+    - Avoid a mad rush at the beginning of each month when each client
+      rotates half of its guards. Instead we spread the rotation out
+      throughout the month, but we still avoid leaving a precise timestamp
+      in the state file about when we first picked the guard. Improves
+      over the behavior introduced in 0.1.2.17.
