Using Boost 1.62, I am seeing the following warning when I build my project.

warning : Boost.Coroutine is now deprecated. Please switch to Boost.Coroutine2. To disable this warning message, define BOOST_COROUTINE_NO_DEPRECATION_WARNING.

I haven't found any documentation on what exactly this means or how to 'switch'. Can someone please point me to some docs or explain what 'switching' entails?
