+  o Minor fixes (relays):
+    - Check that both the ORPort and DirPort (if present) are reachable
+      before publishing a relay descriptor. Otherwise, relays publish a
+      descriptor with DirPort 0 when the DirPort reachability test takes
+      longer than the ORPort reachability test.
+      Closes bug #18050. Reported by "starlight", patch by "teor".
+      Bugfix on 0.1.0.1-rc, commit a1f1fa6ab on 27 Feb 2005.
