+C++1y Feature Support
 ^^^^^^^^^^^^^^^^^^^^^
 
-...
+Clang 3.4 supports all the features in the current working draft of the
+upcoming C++ standard, provisionally named C++1y. Support for the following
+major new features has been added since Clang 3.3:
+
+- Generic lambdas and initialized lambda captures.
+- Deduced function return types (``auto f() { return 0; }``).
+- Generalized ``constexpr`` support (variable mutation and loops).
+- Variable templates and static data member templates.
+- Use of ``'`` as a digit separator in numeric literals.
+- Support for sized ``::operator delete`` functions.
+
+In addition, ``[[deprecated]]`` is now accepted as a synonym for Clang's
+existing ``deprecated`` attribute.
+
+Use ``-std=c++1y`` to enable C++1y mode.
