C++ Language Changes in Clang
-----------------------------
+- We expect this to be the last Clang release that defaults to ``-std=gnu++98``
+ when using the GCC-compatible ``clang++`` driver. From Clang 6 onwards we
+ expect to use ``-std=gnu++14`` or a later standard by default, to match the
+ behavior of recent GCC releases. Users are encouraged to change their build
+ files to explicitly specify their desired C++ standard.
+
- Support for the C++17 standard has been completed. This mode can be enabled
using ``-std=c++17`` (the old flag ``-std=c++1z`` is still supported for
compatibility).
