C++ is a language under constant development, resulting in alternating minor and major releases. The last major release of C++ was C++11. A minor release has just been approved by all participating national bodies (zero negative votes). This will be C++14. C++17 is the next planned major release and is currently under development by the committee.
Rippled has already adopted a number of useful C++14 features. We’ve done this through the development environment where native support is available, or by emulating the features through providing compatible implementations using our beast cxx14 compatibility library ( https://github.com/ripple/rippled/tree/develop/src/beast/beast/cxx14).
