 <h2>Caveats</h2>
 <ul>
+  <li>
+    Two non-standard <tt>std::pair</tt> constructors have been deprecated.
+    These allowed the use of an rvalue and a literal <tt>0</tt> to construct
+    a pair containing a move-only type and a pointer. The <tt>nullptr</tt>
+    keyword should be used to initialize the pointer member instead of a
+    literal <tt>0</tt>, as this is portable to other C++ implementations.
+  </li>
   <li>...</li>
 </ul>
