35 <h1>libc++ C++1z Status</h1>
36 <!--*********************************************************************-->
37
38 <p>In November 2014, the C++ standard committee created a draft for the next version of the C++ standard, known here as "C++1z" (probably to be C++17)</p>
39 <p>This page shows the status of libc++; the status of clang's support of the language features is <a href="http://clang.llvm.org/cxx_status.html#cxx17">here</a>.</p>

41 <p>The groups that have contributed papers:
42 <ul>
43 <li>LWG - Library working group</li>
44 <li>CWG - Core Language Working group</li>
45 <li>SG1 - Study group #1 (Concurrency working group)</li>
