+
+<h2 id="cxx98">C++98 implementation status</h2>
+
+<p>Clang currently implements all of the ISO C++ 1998 standard
+ (including the defects addressed in the ISO C++ 2003 standard)
+ except for 'export' (which has been removed in C++11)
+ and is considered a production-quality C++ compiler. The <a
+ href="http://llvm.org/bugs/">LLVM bug tracker</a> contains a Clang
+ C++ component that tracks known Clang C++ bugs.</p>
+
+<h2 id="cxx11">C++11 implementation status</h2>
+
+ <p>Clang provides support for a number of features included in the new <a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=50372">ISO C++ Standard, ISO/IEC 14882:2011</a>. The following table describes which C++11 features have been implemented in Clang and in which Clang versions they became available.</p>
+
+<p>You can use Clang in C++11 mode either
+with <a href="http://libcxx.llvm.org/">libc++</a> or with gcc's libstdc++.
+Patches are needed to make <a href="libstdc++4.4-clang0x.patch">libstdc++-4.4</a>
+and <a href="libstdc++4.7-clang11.patch">libstdc++-4.7</a> work with Clang in
+C++11 mode.</p>
