Overview
|
||
|
|
================================
|
||
|
|
|
||
|
|
In November 2020, the C++ standard committee adopted the first changes to the next version of the C++ standard, known here as "C++2b" (probably to be C++23).
|
||
|
|
In February 2023, the C++ standard committee approved this draft, and sent it to ISO for approval as C++23.
|
||
|
|
|
||
|
|
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#cxx23>`__.
|
||
|
|
|
||
|
|
.. attention:: Features in unreleased drafts of the standard are subject to change.
|
