@subsection upgrade_740_stdnamespace Standard_Stream.hxx no more has "using std::" statements
*Standard_Stream.hxx* header, commonly included by other OCCT header files, does no more add entities from *std namespace* related to streams (like *std::cout*, *std::istream* and others) into global namespace.
The application code relying on this matter should be updated to either specify std namespace explicitly (like std::cout) or add "using std::" statements locally.
