             Add \tcode{container_value_fn} adaptor and \tcode{_null_predecessor} sentinel for convenience.
       \item Add \tcode{vertex_property_map} facility: a type alias, factory functions, access helpers,
             a value-type trait, and a concept for uniform per-vertex storage across index and mapped graphs.
+      \item Add an allocator parameter to algorithms that require internal containers such as a \tcode{stack}
+            or \tcode{queue}.
