-    <para>Update: <code>std::array</code> is (as of C++11) part of the C++ standard.
-    The differences between <code>boost::array</code> and <code>std::array</code> are minimal.
-    If you are using C++11, you should consider using <code>std::array</code> instead of <code>boost::array</code>.

     <para>Class <code><classname>array</classname></code> fulfills most
     but not all of the requirements of "reversible containers" (see
     Section 23.1, [lib.container.requirements] of the C++

- * 14 Apr 2012 - (mtc) Added support for boost::hash
- * 28 Dec 2010 - (mtc) Added cbegin and cend (and crbegin and crend) for C++Ox compatibility.
  * 10 Mar 2010 - (mtc) fill method added, matching resolution of the standard library working group.
