+[*Deprecated:]
+
+* The chrono i/o version included in Boost.Chrono 1.2.x has been completly refactored in version 2.0.0
+* chrono I/O: The manipulators __duration_short, __duration_long are depreceated. You should use the parameterized form __duration_fmt or the renamed manipulators __duration_symbol and __duration_prefix instead.
+* chrono I/O: The __duration_punct<> facet is depreceated. You should use the __get_duration_style free function to get the informations and use the __duration_units facet for localization purposes.
+
+When BOOST_CHRONO_VERSION==2 the preceding deprecated functions are not available.
