Boost.Range algorithms are now in the boost::range namespace and brought into boost by the appropriate using statement. This allows better interoperation with Boost.Algorithm since errors only occur when the use calls similarly named ambiguous functions. In this event the user can disambiguate by using algorithm::xxx() or range::xxx(). This iteration also updates the concept assert code in the range algorithms.
