API Changes: basic_stream::expires_after used to take a nanosecond duration type argument. This required users on systems where the steady_clock::duration_type was less accurate to explicity duration_cast when calling this function, making code non-portable. The duration type is now that of the embedded steady_clock. Many thanks to @spdw for noticing this and providing a patch. fixes #1943 closes #1960
