The library requires a standard conformant implementation of C++11; a few additional features are only available under C++14/17. Some effort was done to support incomplete language or standard library implementations —see Config—. There are no external dependencies.

The library is continuously tested with the following configurations:

• Clang 3.9, 4, 5
• GCC 5, 6, 7
• Apple LLVM 7.3, 8.3, 9.1
• MSVC 2015, 2017

[Note: Older versions of Clang (3.0+) and GCC (4.6+) are no longer tested, but should still work; please report any issues if you are using them. Older versions of MSVC are not supported.]
