<h1>libc++ C++1z Status</h1>
<!--*********************************************************************-->
<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>
<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>
<p>The groups that have contributed papers:
<ul>
<li>LWG - Library working group</li>
<li>CWG - Core Language Working group</li>
<li>SG1 - Study group #1 (Concurrency working group)</li>
</ul>
