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. | |
