[ChangeLog][General Improvements] Qt's buildsystem now detects whether the compiler supports C++14 and experimental support for C++1z. If the compiler supports it, then Qt is automatically compiled using that support. \ This does not apply to user applications built using qmake: those are still built with C++11 support only. To enable support for C++14 in your application, add to your .pro file: CONFIG += c++14 (similarly for C++1z).
