Currently there are no macros BOOST_NO_CXX11_U16STRING and BOOST_NO_CXX11_U32STRING signaling that the standard library doesn't provides std::u16string or std::u32string. The committed change avoids the compile error when Boost.Config will provide these macros. In the mean time the user needs to define them explicitly while using Boost.Ratio in these conditions. This should go in the library's documentation. The release notes are meant to be a summary, if more detail is required then link to the documentation. Okay. Btw. IMO you shouldn't require the user to define macros just to be able to compile the library, is u32string support really that important?
Well, support for u16string and u32 string has been delivered long time ago, so removing them seems not an alternative, or is it? I have proposed a patch to Boost.Config that I expect will be available for the next release. The case where this is needed is a corner case IMO, as the user is using c++11 without a c++ standard library. I know clang is the typical example, but the user can install libc++ which is also free.
