@.. _cxx2a-status:

================================
libc++ C++20 Status
================================

.. include:: Helpers/Styles.rst

.. contents::
   :local:


Overview
================================

In July 2017, the C++ standard committee created a draft for the next version of the C++ standard, initially known as "C++2a".
In September 2020, the C++ standard committee approved this draft, and sent it to ISO for approval as C++20.

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#cxx20>`__.

.. 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.

   .. [#note-P0966] P0966: It was previously erroneously marked as complete in version 8.0. See `bug 45368 <https://llvm.org/PR45368>`__.

   .. [#note-P0619] P0619: Only ``std::allocator`` part is implemented.
