+Sol makes use of C++11 **and** C++14 features. GCC 5.x.x and Clang 3.6.x (with std=c++1z and appropriate standard library) 
+or higher should be able to compile without problems.  However, the officially supported and CI-tested compilers are:
 
-- GCC 4.9.0+
-- Clang 3.5+
+- GCC 5.x.x+
+- Clang 3.6.x+
 - Visual Studio 2015 Community (Visual C++ 14.0)+
 
+Please make sure you use the `-std=c++1y`, `-std=c++14`, `-std=c++1z`, `-std=c++17` or better  standard flags 
+(some of these flags are the defaults in later versions of GCC 6+ and better).
+
+Older compilers (GCC 4.9.x, Clang 3.4.x seem to be the lowest) can work with versions as late 
+as [v2.17.5](https://github.com/ThePhD/sol2/releases/tag/v2.17.5), with the flag `-std=c++14` or `-std=c++1y`.
