+Overview
+================================
+
+In November 2014, the C++ standard committee created a draft for the next version of the C++ standard, initially known as "C++1z".
+In February 2017, the C++ standard committee approved this draft, and sent it to ISO for approval as C++17.
+
+This page shows the status of libc++; the status of clang's support of the language features is `here <https://clang.llvm.org/cxx_status.html#cxx17>`__.
+
+.. attention:: Features in unreleased drafts of the standard are subject to change.
+
+The groups that have contributed papers:
+
+-  CWG - Core Language Working group
+-  LWG - Library working group
+-  SG1 - Study group #1 (Concurrency working group)
+
+.. note:: "Nothing to do" means that no library changes were needed to implement this change.
