- * 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.
- *      See <http://www.open-std.org/jtc1/sc22/wg21/docs/lwg-defects.html#776> or Trac issue #3168
- *      Eventually, we should remove "assign" which is now a synonym for "fill" (Marshall Clow)
- * 10 Mar 2010 - added workaround for SUNCC and !STLPort [trac #3893] (Marshall Clow)
  * 29 Jan 2004 - c_array() added, BOOST_NO_PRIVATE_IN_AGGREGATE removed (Nico Josuttis)
  * 23 Aug 2002 - fix for Non-MSVC compilers combined with MSVC libraries.
  * 05 Aug 2001 - minor update (Nico Josuttis)
