+          <p>
+	    Improve search algorithm of abandoned memory carriers.
+	    Instead of limited linear search, each allocator instance
+	    maintain a balanced search tree of all its abandoned
+	    carriers for faster and more exhaustive search.</p>

+	    New erts_alloc command line options <c>+M_acnl</c> and
+	    <c>+M_acfml</c> to limit carrier abandonment.</p>

+        <item>
+          <p>
+	    New family of <c>erts_alloc</c> strategies: Age Order
+	    First Fit. Similar to "address order", but instead the
+	    oldest possible carrier is always chosen for allocation.</p>
+          <p>

+        </item>
+        <item>
+          <p>
+	    Add possibility to change allocator options at runtime
+	    with <c>system_info(erts_alloc, ...)</c>. Only option
+	    <c>sbct</c> (single block carrier threshold) is currently
+	    supported via this interface.</p>
