+  o Minor features (defensive programming):
+    - Most of the functions in Tor that free objects have been replaced
+      with macros that free the objects and set the corresponding pointers
+      to NULL. This change should help prevent a large class of dangling
+      pointer bugs. Closes ticket 24337.
+
+    - Where possible, the tor_free() macro now only evaluates its input once.
+      Part of ticket 24337.
