+  o Code simplification and refactoring:
+
+    - Remove our old, non-weighted bandwidth-based node selection code.
+      Previously, we used it as a fallback when we couldn't perform
+      weighted bandwidth-based node selection.  But that would only
+      happen in the cases where we had no consensus, or when we had a
+      consensus generated by buggy or ancient directory authorities.  In
+      either case, it's better to use the more modern, better maintained
+      algorithm, with reasonable defaults for the weights. Closes
