 ### Properties
 
-* C++03 **(will be raised to C++11 by mid 2020)**
-* optional C++11/17 support
+* optional C++17 (filesystem) support
 * Usable outside of Boost via CMake
 * Compiled library on every OS
 
 Note on the last point:
 Having a compiled library allows cross-platform access to e.g. `setenv` which would not be available when using a `-std=c++nn` flag.
 This is different to the version available prior to the inclusion in Boost.
 
+### Requirements (All versions)
+
+* C++11 (or higher) compatible compiler
+    * MSVC 2015 and up work
+    * libstdc++ < 5 is unsupported as it is silently lacking C++11 features
+
 ### Requirements (Boost version)
 
-* C++03 (or higher) compatible compiler
 * Boost (>= 1.56)
 * CMake (when not using as part of Boost) or B2 (otherwise)
