-  o Major bugfixes (also in 0.2.3.24-rc):
+  Tor 0.2.3.24-rc comes hard at the heels of 0.2.4.4-alpha, to fix two
+  important security vulnerabilities that could lead to remotely
+  triggerable relay crashes, fixes a major bug that was preventing
+  clients from choosing good exit nodes, and refactor some of our code.
+
+  o Major bugfixes (security, also in 0.2.3.24-rc):
+    - Fix a group of remotely triggerable assertion failures related to
+      incorrect link protocol negotiation. Found, diagnosed, and fixed
+      by "some guy from France." Fix for CVE-2012-2250; bugfix on
+      0.2.3.6-alpha.
     - Fix a denial of service attack by which any directory authority
       could crash all the others, or by which a single v2 directory
       authority could crash everybody downloading v2 directory
       information. Fixes bug 7191; bugfix on 0.2.0.10-alpha.

       an exit relay would allow exiting to an internal address. Fixes
       bug 7190; bugfix on 0.2.3.1-alpha.
-  o Code simplification and refactoring:
-    - Start using OpenBSD's implementation of queue.h (originally by Niels
-      Provos).
-    - Move the entry node code from circuitbuild.c to its own file.
-    - Move the circuit build timeout tracking code from circuitbuild.c
-      to its own file.

   o Minor bugfixes:
     - Only disable TLS session ticket support when running as a TLS
       server. This keeps clients harder to distinguish from regular firefox
       connections. Fixes bug 7189; bugfix on Tor 0.2.3.23-rc.
