     <title>Appending to a Binary</title>
-    <p>Since Erlang R12B, the following function for creating a binary out of
-    a list of triples of integers is efficient:</p>
+    <p>Appending to a binary in an efficient way can be done as follows:</p>
     <code type="none"><![CDATA[

 triples_to_bin([{X,Y,Z} | T], Acc) ->

-    <p>In previous releases, this function was highly inefficient, because
-    the binary constructed so far (<c>Acc</c>) was copied in each recursion step.
-    That is no longer the case. For more information, see
