This adjust the version macro and sets it as completed. All parts of the paper have been implemented, except for the parts replaced by later papers and LWG-issues. Adjusted the synopsis to match the synopsis in the Standard. Not yet implemented parts of P2216 and P2418 still use the P0645 wording.

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.

|
|
.. [#note-P0645] P0645: The paper is implemented but still marked as an incomplete feature. Not yet implemented LWG-issues will cause API and ABI breakage.
|
|
.. [#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 sections D.8, D.9, D.10 and D.13 are implemented. Sections D.4, D.7, D.11, D.12, and D.14 remain undone.
|
|
.. [#note-P0883] P0883: shared_ptr and floating-point changes weren't applied as they themselves aren't implemented yet.
