C++ Language Changes in Clang<br>

+- Clang's default C++ dialect is now ``gnu++14`` instead of ``gnu++98``. This<br>
+ means Clang will by default accept code using features from C++14 and<br>
+ conforming GNU extensions. Projects incompatible with C++14 can add<br>
+ ``-std=gnu++98`` to their build settings to restore the previous behaviour.<br>
