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

In June 2023, the C++ standard committee adopted the first changes to the next version of the C++ standard, known here as "C++2c" (probably to be C++26).

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#cxx2c>`__.

.. 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.
