| 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#cxx2a>`__. | |
